Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic view of a wearable device provided in an embodiment of the present application.

As shown in fig. 1, the wearable device provided in the embodiment of the present application includes a wearable main body 110, a wearable belt 120, a first antenna module 130, and a second antenna module 140, where the wearable main body 110 is connected to the wearable belt 120; the first antenna module 130 is disposed on the wearing body 110, and the second antenna module 140 is disposed on the wearing band 120; the phase difference between the first antenna module 130 and the second antenna module 140 is adjustable, so that the pattern of the antenna array including the first antenna module 130 and the second antenna module 140 is adjustable; the first antenna module 130 is an active antenna module, and the second antenna module 140 is a passive antenna module.

The first antenna module 130 and the second antenna module 140 may both be antennas for communication, such as a broadcast antenna and a WIFI antenna, or may be antennas for positioning, or may be other types of antennas.

The phase of the second antenna module 140 can be adjusted, and the first antenna module 130 and the second antenna module 140 can operate simultaneously.

When the first antenna module 130 is an active antenna module and the second antenna module 140 is a passive antenna module; the electromagnetic field of the first antenna module 130 may form an induced current; the induced current formed by the electromagnetic field of the first antenna module 130 may feed the second antenna module 140.

Thus, the first antenna module 130 is an active antenna module, and the sensitivity of receiving signals is high; the second antenna module 140 is a passive antenna module, and thus, no rf communication signal is required to be input, and the rf design of the first antenna module 130 is not affected.

It will be appreciated that the distribution of the radiowave energy radiated by the antenna in the spatial direction is generally not uniform; in the case where the wearable device has only the first antenna module 130, there may be a problem of poor radiation effect. For example, when the wearing body of the wearable device is biased to the ground and the maximum beam of the first antenna module 130 is directed to the ground, the radiation effect of the antenna is poor. The largest beam of the antenna refers to the main beam of the antenna, i.e. the main lobe of the antenna's directional pattern.

However, when the wearable device has both the first antenna module 130 and the second antenna module 140, the first antenna module 130 and the second antenna module 140 may form an antenna array. The phase difference between the first antenna module 130 and the second antenna module 140 can be adjusted by adjusting the phase of the second antenna module 140, so as to adjust the directional diagram of the antenna array, so that the maximum beam of the antenna array is not directed to the ground.

Therefore, the wearable device provided by the embodiment of the present application includes a wearable main body 110, a wearable belt 120, a first antenna module 130, and a second antenna module 140, where the wearable main body 110 is connected to the wearable belt 120; the first antenna module 130 is disposed on the wearing body 110, and the second antenna module 140 is disposed on the wearing band 120; the phase difference between the first antenna module 130 and the second antenna module 140 is adjustable, so that the directional pattern of the antenna array including the first antenna module and the second antenna module is adjustable; the first antenna module is an active antenna module, and the second antenna module is a passive antenna module. Therefore, the second antenna module 140 is added on the basis of the first antenna module 130, the phase difference between the first antenna module 130 and the second antenna module 140 can be adjusted, the directional diagram of the antenna array formed by the first antenna module 130 and the second antenna module 140 can be adjusted by adjusting the phase difference, and the radiation effect of the antenna array is further improved.

As described above, the phase difference between the first antenna module 130 and the second antenna module 140 can be adjusted by adjusting the phase of the second antenna module 140, so as to adjust the directional pattern of the antenna array. The phase of the second antenna module 140 can be adjusted by adjusting the working length of the second antenna module 140 (i.e. the effective physical length of the second antenna module 140 for working) and adjusting the distance between the first antenna module 130 and the second antenna module 140. The principle is as follows:

assuming that the antenna types of the first antenna module 130 and the second antenna module 140 are dipole antennas, the current of the first antenna module 130 is I₁The current of the second antenna module 140 is I₂The first antenna module 130 and the second antenna module 140 are disposed in parallel with a distance d. Assuming that the oscillator currents are distributed in a sinusoidal manner, a directional pattern function of the antenna array formed by the first antenna module 130 and the second antenna module 140 can be obtained through approximate calculation:

where m represents the current amplitude ratio I of the two element antennas₂|/|I₁And l, calculating by using an impedance equation of the coupled oscillator to obtain:

wherein R and X represent resistance and reactance, respectively, R₂₁A resistance part, X, representing the mutual impedance of the second antenna module 140₂₁A reactive component, R, representing the mutual impedance of the second antenna module 140₂₂A resistance part, X, representing the self-impedance of the second antenna module 140₂₂Representing the reactive part of the self-impedance of the second antenna module 140,indicating the phase of the second antenna module 140. The directional pattern of the antenna array can be changed by changing the self-impedance and the mutual impedance of the second antenna module 140, the mutual impedance of the second antenna module 140 can be changed by changing the distance d, and the self-impedance of the second antenna module 140 can be changed by changing the structural size, such as the length, of the second antenna module 140.

Although the actual antenna structure shape and the spatial relationship between the antennas are complex, and it is difficult to express the amplitude and phase relationship between the passive antenna and the active antenna by a simple formula, it is the same in principle, and the mutual impedance is changed by changing the distance between the passive antenna and the active antenna, and the self impedance is changed by changing the length of the passive antenna, and the mutual impedance and the self impedance affect the amplitude and phase of the induced field of the passive antenna, thereby affecting the directional patterns of the passive antenna (the second antenna module 140) and the active antenna (the first antenna module 130).

Fig. 2 is a schematic view of a wearing belt of a wearing device provided in an embodiment of the present application.

As shown in fig. 2, in order to adjust the working length of the second antenna module 140, the wearable device provided in the embodiment of the present application may further include a switch component 150, where a phase difference between the first antenna module 130 and the second antenna module 140 is adjustable through the switch component 150; the switch component 150 may have a first end 151 and a plurality of second ends 152, the first end 151 of the switch component 150 may be grounded, and the plurality of second ends 152 of the switch component 150 may be connected to the second antenna module 140.

Alternatively, as shown in fig. 2, the positions of the plurality of second ends 152 of the switch component 150 connected to the second antenna module 140 may all be different.

As shown in fig. 2, the second end 152 may include a first second end 1521, a second end 1522, a third second end 1523, and a fourth second end 1524.

Optionally, a control circuit for controlling the switch assembly may be included in the switch assembly 150. The first end 151 of the switch assembly 150 may be grounded, and specifically, the first end 151 may be connected to a grounding member, which may be a metal plate with a potential of 0.

The working length of the second antenna module 140 can be adjusted by adjusting the connection state of the first end 151 and the second end 152 of the switch component 150. For example, when the first end 151 is connected to the first second end 1521, the working length of the second antenna module 140 is L1; when the first end 151 is connected to the second end 1522, the working length of the second antenna module 140 is L2; when the first end 151 is connected to the third end 1523, the working length of the second antenna module 140 is L3; when the first end 151 is connected to the fourth second end 1524, the working length of the second antenna module 140 is L4, and obviously, there is a relationship of L1> L2> L3> L4. It should be noted that fig. 2 only shows the working lengths L1 and L2 of the second antenna module 140, and as can be seen from L1 and L2 shown in fig. 2, when the working length of the second antenna module 140 is L3, the L3 is the length from the position where the second end 1523 is connected to the second antenna module 140 to the rightmost end of the second antenna module 140 in fig. 2; the L4 is a length from a position where the second end 1524 is connected to the second antenna module 140 to a rightmost end of the second antenna module 140 in fig. 2.

Fig. 3 is a schematic side view of a wearable device according to an embodiment of the present disclosure.

As shown in fig. 3, only the side of the wearing body 110, the side of the wearing band 120, the side of the first antenna module 130, and the side of the second antenna module 140 are shown in fig. 3. Assuming that the induced field of the second antenna module 140 is the same phase as the first antenna module 130, the working length of the second antenna module is L0. When L0 and L1, L2, L3, and L4 satisfy the relationship of L1> L2> L0> L3> L4, the phase of the second antenna module 140 lags behind the first antenna module 130 when the working lengths are L1 and L2, and the pattern of the antenna array is biased to the second antenna module 140 side; due to the reflection action of the floor, finally, when the working length of the second antenna module 140 is L1 and L2, the directional pattern of the antenna array will be deviated to the upper right as shown in fig. 3, and when the working length of the second antenna module 140 is L2, the directional pattern of the antenna array is as shown in fig. 3 as directional pattern three 163; since the phase lags more when the operating length of the second antenna module 140 is L1, the pattern of the antenna array is as shown in fig. 3 as pattern four 164 when the operating length of the second antenna module 140 is L1; when the working lengths are L3 and L4, the phase of the second antenna module 140 is advanced from the first antenna module 130, and the pattern of the antenna array is biased to one side of the first antenna module 130; due to the reflection action of the upper floor of the belt, finally, when the working length of the second antenna module 140 is L3 and L4, the directional pattern of the antenna array will be deviated to the upper left as shown in fig. 3, and when the working length of the second antenna module 140 is L3, the directional pattern of the antenna array is as shown in fig. 3 as directional pattern two 162; since the phase is advanced more when the working length of the second antenna module 140 is L4, the directional pattern of the antenna array is the first directional pattern 161 shown in fig. 3 when the working length of the second antenna module 140 is L4. And the maximum beams in the first directional diagram, the second directional diagram, the third directional diagram and the fourth directional diagram are not directed to the ground.

It is understood that the second end 152 may include only two second ends, three second ends, four second ends, or more second ends. Accordingly, by adjusting the connection state of each of the first terminal 151 and the second terminal 152 of the switch component 150, the working length of the second antenna module 140 may have two different values, three different values, four different values, or more different values. The maximum beam of the directional pattern of the antenna array may have two different directions, three different directions, four different directions, or more different directions. As long as the working length of the second antenna module 140 meets a certain requirement, that is, the working length of the second antenna module 140 does not exceed or is not less than a preset value, which causes the maximum beam in the directional diagram not to point to the ground, the maximum beam of the directional diagram does not point to the ground.

Thus, the switch element 150 has a plurality of second ends, so that the first end of the switch element 150 can be connected to one of the second ends of the switch element 150, so as to change the working length of the second antenna module 140, further change the phase of the second antenna module 140, change the phase difference between the second antenna module 140 and the first antenna module 130, and finally realize the change of the directional diagram of the antenna array.

Alternatively, as shown in fig. 2, in a case where positions of the plurality of second terminals 152 of the switch component 150, to which the second antenna module 140 is connected, are different, positions of the plurality of second terminals 152, to which the second antenna module 140 is connected, may all be located on the same straight line, and a distance between positions of any two adjacent second terminals, to which the second antenna module 140 is connected, may be constant.

Thus, the positions of the second ends 152 connected with the second antenna module 140 are all located on the same straight line, and the distance between any two adjacent second ends and the position of the second antenna module 140 is constant, so that the layout in the switch assembly is relatively neat, and the switch assembly is convenient to manufacture and overhaul in the subsequent use process.

It should be noted that the positions where each of the second ends 152 is connected to the second antenna module 140 may be located on the same straight line, or may not be located on the same straight line; the distance between the positions where any two adjacent second ends are connected to the second antenna module 140 may or may not be constant. In practical applications, the distance between the positions where any two adjacent second ends are connected to the second antenna module 140 may be designed according to specific requirements.

Fig. 4 is a schematic view of a wearing belt of another wearing device provided in the embodiments of the present application.

As shown in fig. 4, the positions of the plurality of second ends 152 of the switch assembly 150 connected to the second antenna module 140 are the same, and the wearable device may further include: a reactance device 170; the phase difference between the first antenna module 130 and the second antenna module 140 is adjustable through the switch component 150 and the reactance device 170; there is at least one designated second terminal among the plurality of second terminals 152 of the switch assembly 150, the at least one designated second terminal being connected with the second antenna module 140 through the reactance device 170; wherein the reactive component 170 comprises a capacitance or an inductance.

It should be noted that fig. 4 shows a case where positions of the plurality of second ends 152 of the switch component 150, which are connected to the second antenna module 140, are the same, and positions of the plurality of second ends 152 of the switch component 150, which are connected to the second antenna module 140, may also be different.

Alternatively, the number of the reactance devices 170 may be plural. Specifically, the reactance device 170 may include only a plurality of capacitances or only a plurality of inductances; the capacitor can also simultaneously comprise a plurality of capacitors and a plurality of inductors, and also can simultaneously comprise one capacitor and a plurality of inductors; the inductor and the capacitors can be simultaneously included.

In the case where the number of the reactance devices 170 is plural, plural reactance devices may be connected in parallel.

It can be understood that, in a case that the reactance device includes a capacitor, connecting the at least one designated second terminal to the capacitor, and then connecting the at least one designated second terminal to the second antenna module 140 is equivalent to lengthening the working length of the second antenna module 140, and the larger the capacitance value of the capacitor is, the longer the equivalent working length of the second antenna module 140 is. In the case that the reactance device includes an inductor, after the at least one designated second end is connected to the inductor, the reactance device is connected to the second antenna module 140, which is equivalent to shortening the working length of the second antenna module 140, and the smaller the inductance value of the inductor, the shorter the equivalent working length of the second antenna module 140.

In this way, the working length of the second antenna module 140 can be adjusted by providing a reactance device between the second end of the switch component 150 and the second antenna module 140.

Fig. 5 is a schematic view of a wearing belt of another wearing device provided in the embodiments of the present application.

It should be noted that fig. 5 illustrates a case where positions of the plurality of second terminals 152 of the switch component 150, which are connected to the second antenna module 140, are different.

As shown in fig. 4, in the case that the positions of the plurality of second terminals 152 of the switch component 150, at which the respective second terminals are connected to the second antenna module 140, are the same, the at least one designated second terminal may be connected to the second antenna module 140 through the reactance device 170, and at this time, the working length of the second antenna module 140 is changed only through the switch component 150 adjusting the connected reactance device 170.

As shown in fig. 5, in a case where the positions of the plurality of second terminals 152 of the switch component 150, which are connected to the second antenna module 140, are different, the at least one designated second terminal may also be connected to the second antenna module 140 through the reactance device 170, and at this time, the working length of the second antenna module 140 may be changed by adjusting the access length of the second antenna module 140 and adjusting the accessed reactance device 170 at the same time.

Optionally, in an embodiment of the present application, the wearable device includes a wearable main body 110, a wearable band 120, a first antenna module 130, a second antenna module 140, and a reactance device 170 (excluding the switch component 150); the phase difference between the first antenna module 130 and the second antenna module 140 is adjustable through the reactance device 170; the reactance device 170 has a first end and a second end, the first end of the reactance device 170 is grounded, and the second end of the reactance device 170 is connected with the second antenna module 140.

In this case, the wearable device provided by the embodiment of the present application adjusts the working length of the second antenna module 140 only by connecting the reactance device. As described above, the access capacitance is equivalent to lengthening the working length of the second antenna module 140, and the access inductance is equivalent to shortening the working length of the second antenna module 140. Therefore, the reactive device can be switched in to adjust the working length of the second antenna module 140.

In this way, the working length of the second antenna module 140 can be adjusted only by the connected reactance device.

On the basis that the wearable device provided by the embodiment of the present application includes the reactance device 170, the wearable device may further include a switch component 150 (as shown in fig. 4 and 5), the switch component 150 may have a first end 151 and a plurality of second ends 152, the first end 151 of the switch component 150 is grounded, and the plurality of second ends 152 of the switch component 150 are all connected to the second antenna module 140; the positions of the plurality of second terminals 152 of the switch component 150, which are connected to the second antenna module 140, may be the same (as shown in fig. 4), and the positions of the plurality of second terminals 152 of the switch component 150, which are connected to the second antenna module 140, may also be different (as shown in fig. 5).

Fig. 6 is a schematic view of a wearing belt of another wearing device provided in the embodiments of the present application.

As shown in fig. 6, the second antenna module 140 may include a first sub-antenna 141 and a second sub-antenna 142, and the first sub-antenna 141 and the second sub-antenna 142 are separated by a predetermined distance.

It is understood that, although the following description takes the second antenna module 140 as including the first sub-antenna 141 and the second sub-antenna 142 as an example, the second antenna module 140 may further include a plurality of sub-antennas, such as a third sub-antenna and a fourth sub-antenna, and the number of sub-antennas included in the second antenna module 140 is not limited herein. The wearable device may further include a switch assembly including a first switch element 181 and/or a second switch element 182, and a phase difference between the first antenna module 130 and the second antenna module 140 may be adjustable through the first switch element 181 and/or the second switch element 182.

In the case where the switching assembly includes the first switching element 181, one end of the first switching element 181 is connected to the first sub antenna 141, and the other end of the first switching element 181 is grounded. The first switching element 181 is connected to the end of the first sub antenna 141.

In the case where the switching assembly includes the second switching element 182, one end of the second switching element 182 is connected to the second sub antenna 142, and the other end of the second switching element 182 is grounded. The second switching element 182 is connected to an end of the second sub antenna 142.

In the case where the switching assembly includes a first switching element 181 and a second switching element 182, one end of the first switching element 181 is connected to the first sub antenna 141, and the other end of the first switching element 181 is grounded; one end of the second switch element 182 is connected to the second sub-antenna 142, and the other end of the second switch element 182 is grounded.

It is understood that, in the case that the switching assembly includes the first switching element 181, one end of the first sub antenna 141 is grounded, and the other end is connected to the first switching element 181; when the end of the first switch element 181 connected to the first sub-antenna 141 is connected to the end of the first switch element 181 connected to the ground, the first sub-antenna 141 is short-circuited, that is, the first sub-antenna 141 does not operate; when the end of the first switch element 181 connected to the first sub-antenna 141 is not connected to the end of the first switch element 181 connected to the ground, the first sub-antenna 141 operates.

In the case where the switching assembly includes the second switching element 182, one end of the second sub-antenna 142 is grounded, and the other end is connected to the second switching element 182; when the end of the second switch element 182 connected to the second sub-antenna 142 is connected to the end of the second switch element 182 connected to the ground, the second sub-antenna 142 is short-circuited, that is, the second sub-antenna 142 does not operate; under the condition that the end of the second switch element 182 connected to the second sub-antenna 142 is not connected to the end of the second switch element 182 connected to the ground, the second sub-antenna 142 operates.

In the case where the switching assembly includes the first switching element 181 and the second switching element 182, one end of the first sub antenna 141 is grounded, and the other end is connected to the first switching element 181; one end of the second sub-antenna 142 is grounded, and the other end is connected to the second switch element 182. When the end of the first switch element 181 connected to the first sub-antenna 141 is connected to the end of the first switch element 181 grounded, and the end of the second switch element 182 connected to the second sub-antenna 142 is not connected to the end of the second switch element 182 grounded, the first sub-antenna 141 does not operate, and the second sub-antenna 142 operates. When the end of the first switch element 181 connected to the first sub-antenna 141 is not connected to the end of the first switch element 181 grounded, and when the end of the second switch element 182 connected to the second sub-antenna 142 is connected to the end of the second switch element 182 grounded, the first sub-antenna 141 is operated, and the second sub-antenna 142 is not operated.

Since the first sub-antenna 141 and the second sub-antenna 142 are separated by a predetermined distance, the distance between the first antenna module 130 and the first sub-antenna 141 is different from the distance between the first antenna module 130 and the second sub-antenna 142.

Fig. 7 is a schematic side view of another wearable device provided in an embodiment of the present application.

As shown in FIG. 7, if the working length of the first sub-antenna 141 is controlled to lead the phase thereof to be ahead of the phase A of the first antenna module 130₁The working length of the second sub-antenna 142 is controlled to lead the phase a of the first antenna module 130₂，A₁Is less than A₂Then, when only the first sub-antenna 141 is operated, the corresponding pattern is the second pattern 192 in fig. 7, and when only the second sub-antenna 142 is operated, the corresponding pattern is the first pattern 191 in fig. 7. If the working length of the first sub-antenna 141 is controlled to lag the phase A of the first antenna module 130₁The working length of the second sub-antenna 142 is controlled to lag the phase A of the first antenna module 130₂，A₁Is less than A₂Then the pattern corresponding to the operation of only the first sub-antenna 141 is the third pattern 193 in fig. 7, and the pattern corresponding to the operation of only the second sub-antenna 142 is the fourth pattern 194 in fig. 7.

Thus, the distance between the first antenna module 130 and the working sub-antenna in the second antenna module 140 can be changed by switching the connection state between the end of the first switch element 181 connected to the first sub-antenna 141 and the end of the first switch element 181 grounded, and the connection state between the end of the second switch element 182 connected to the second sub-antenna 142 and the end of the second switch element 182 grounded, so as to adjust the phase of the second antenna module 140, and adjust the directional pattern of the antenna array formed by the first antenna module 130 and the second antenna module 140.

Fig. 8 is a schematic view of a wearing belt of another wearing device provided in the embodiments of the present application.

As shown in fig. 8, the switch assembly further includes a third switch element 183 and/or a fourth switch element 184, and a phase difference between the first antenna module 130 and the second antenna module 140 is adjustable by the third switch element 183 and/or the fourth switch element 184.

In the case where the switch assembly includes the third switch element 183, the third switch element 183 has a first end and a plurality of second ends, the first end of the third switch element 183 is grounded, and the plurality of second ends of the third switch element 183 are connected to the first sub-antenna 141.

At this time, when one end of the first sub-antenna 141 is grounded through the first switch element 181 and the other end of the first sub-antenna 141 is grounded through the third switch element 183, the first sub-antenna 141 does not operate. In the case where the first sub antenna 141 is operated without connecting one end of the first sub antenna 141 to the ground through the first switching element 181, the operation length of the first sub antenna 141 may be changed by adjusting the connection state of the first end and each second end of the third switching element 183. The principle is the same as described above for fig. 2.

The positions of the plurality of second ends of the third switching element 183, which are connected to the first sub-antenna 141, may be different, and the positions of the plurality of second ends of the third switching element 183, which are connected to the first sub-antenna 141, may also be the same; in the case where the positions at which the respective second terminals of the plurality of second terminals of the third switching element 183 are connected to the first sub-antenna 141 are the same, the working length of the first sub-antenna 141 may be adjusted by loading a reactive device on the third switching element 183. Fig. 8 shows only a case where the positions of the respective second terminals of the plurality of second switching elements 183 connected to the first sub antenna 141 are different.

In the case that the switch assembly includes a fourth switch element 184, the fourth switch element 184 has a first end and a plurality of second ends, the first end of the fourth switch element 184 is grounded, and the plurality of second ends of the fourth switch element 184 are connected to the second sub-antenna 142.

At this time, when one end of the second sub-antenna 142 is grounded through the second switching element 182 and the other end of the second sub-antenna 142 is grounded through the fourth switching element 184, the second sub-antenna 142 does not operate. In the case where one end of the second sub-antenna 142 is not grounded through the second switch element 182, the second sub-antenna 142 operates, and at this time, the operating length of the second sub-antenna 142 may be changed by adjusting the connection state of the first end and each second end in the fourth switch element 184. The principle is the same as described above for fig. 2.

The positions of the second terminals of the plurality of second terminals of the fourth switch element 184 connected to the second sub-antenna 142 may all be different, and the positions of the second terminals of the plurality of second terminals of the fourth switch element 184 connected to the second sub-antenna 142 may also all be the same; in the case that the positions of the second terminals of the fourth switching element 184 connected to the second sub-antenna 142 are the same, the working length of the second sub-antenna 142 may be adjusted by loading a reactance device on the fourth switching element 184.

Fig. 8 shows only a case where each of the plurality of second terminals of the fourth switching element 184 is connected to the second sub antenna 142 at a different position.

In the case where the switch assembly includes a third switch element 184 and a fourth switch element 184, the third switch element 183 has a first end and a plurality of second ends, the first end of the third switch element 183 is grounded, and the plurality of second ends of the third switch element 183 are connected to the first sub-antenna 141; the fourth switching element 184 has a first end and a plurality of second ends, the first end of the fourth switching element 184 is grounded, and the plurality of second ends of the fourth switching element 184 are connected to the second sub-antenna 142.

The positions of the plurality of second ends of the third switching element 183, which are connected to the first sub-antenna 141, may be different, and the positions of the plurality of second ends of the third switching element 183, which are connected to the first sub-antenna 141, may also be the same; in the case where the positions at which the respective second terminals of the plurality of second terminals of the third switching element 183 are connected to the first sub-antenna 141 are the same, the working length of the first sub-antenna 141 may be adjusted by loading a reactive device on the third switching element 183. The positions of the second terminals of the plurality of second terminals of the fourth switch element 184 connected to the second sub-antenna 142 may all be different, and the positions of the second terminals of the plurality of second terminals of the fourth switch element 184 connected to the second sub-antenna 142 may also all be the same; in the case that the positions of the second terminals of the fourth switching element 184 connected to the second sub-antenna 142 are the same, the working length of the second sub-antenna 142 may be adjusted by loading a reactance device on the fourth switching element 184.

Fig. 8 shows only the case where the positions of the respective second terminals of the plurality of second terminals of the third switching element 183 connected to the first sub antenna 141 are different from the positions of the respective second terminals of the plurality of second terminals of the fourth switching element 184 connected to the second sub antenna 142.

At this time, while the sub-antenna for operation in the second antenna module 140 is switched by the first and second switching elements 181 and 182, the operating length of the first or second sub-antenna 141 or 142 may be changed by the third and fourth switching elements 183 and 184.

Thus, the phase of the second antenna module 140 can be changed in various ways, so as to adjust the pointing direction of the maximum beam in the directional diagram of the antenna array, thereby providing various selectable directional diagrams.

Optionally, the wearable device may further include: a first reactive device and/or a second reactive device through which a phase difference between the first antenna module 130 and the second antenna module 140 is adjustable.

In case the switch assembly comprises a third switch element 183; positions at which each of the plurality of second terminals of the third switching element 183 is connected to the first sub-antenna may be the same, and positions at which each of the plurality of second terminals of the third switching element 183 is connected to the first sub-antenna 141 may be different; there is at least one first target second terminal among the plurality of second terminals of the third switching element 183, the first target second terminal being connected with the first sub antenna 141 through the first reactive device;

in a case where the switch component includes a fourth switch element 184, positions at which the respective second terminals of the plurality of second terminals of the fourth switch element 184 are connected to the first sub-antenna may be the same, and positions at which the respective second terminals of the plurality of second terminals of the fourth switch element 184 are connected to the second sub-antenna 142 may also be different; there is at least one second target second terminal among the plurality of second terminals of the fourth switching element 184, the second target second terminal being connected with the second sub antenna 142 through the second reactive device;

in the case where the switch assembly includes a third switch element 183 and a fourth switch element 184, positions at which respective second ends of the plurality of second ends of the third switch element 183 are connected to the first sub-antenna may be the same, and positions at which respective second ends of the plurality of second ends of the third switch element 183 are connected to the first sub-antenna 141 may also be different; the positions of the plurality of second terminals of the fourth switch element 184 connected to the first sub-antenna may be the same, and the positions of the plurality of second terminals of the fourth switch element 184 connected to the second sub-antenna 142 may be different; there is at least one first target second terminal among the plurality of second terminals of the third switching element 182, the first target second terminal being connected with the first sub antenna 141 through the first reactive device; there is at least one second target second terminal among the plurality of second terminals of the fourth switching element 184, and the second target second terminal is connected to the second sub antenna 142 through the second reactive device.

Optionally, the number of the first reactance device and/or the second reactance device may be multiple. In particular, the first reactive device and/or the second reactive device may comprise only a plurality of capacitances or a plurality of inductances; the capacitor can also simultaneously comprise a plurality of capacitors and a plurality of inductors, and also can simultaneously comprise one capacitor and a plurality of inductors; the inductor and the capacitors can be simultaneously included.

In the case where the number of the first reactance devices is plural, the plural first reactance devices may be connected in parallel. In the case where the number of the second reactance devices is plural, the plural second reactance devices may be connected in parallel.

It can be understood that, after the second end of the at least one target is connected to the capacitor, the second end is connected to the first sub-antenna 141 and/or the second sub-antenna 142, which is equivalent to lengthening the working length of the first sub-antenna 141 and/or the second sub-antenna 142, and the larger the capacitance value of the capacitor, the longer the equivalent working length of the first sub-antenna 141 and/or the second sub-antenna 142; after the second end of the at least one target is connected to the inductor, the second end of the at least one target is connected to the first sub-antenna 141 and/or the second sub-antenna 142, which is equivalent to shortening the working length of the first sub-antenna 141 and/or the second sub-antenna 142, and the smaller the inductance value of the inductor is, the shorter the equivalent working length of the first sub-antenna 141 and/or the second sub-antenna 142 is.

In this way, on the basis that the sub-antenna operating in the second antenna module 140, that is, the distance between the first antenna module 130 and the second antenna module 140, can be adjusted, the reactance device can be further arranged to adjust the operating length of the first sub-antenna 141 and/or the second sub-antenna 142.

It should be noted that the antenna types of the first antenna module 130 and the second antenna module 140 in the embodiment of the present application may be monopole antennas, IFA antennas (i.e., inverted F antennas), or other types of antennas.

In one embodiment of the present application, the wearable device includes a wearable main body 110, a wearable band 120, a first antenna module 130, a second antenna module 140, a first target reactance device, and a second target reactance device; the second antenna module 140 may include a first sub-antenna 141 and a second sub-antenna 142 (excluding the switch component 150); the phase difference between the first antenna module 140 and the second antenna module 142 is adjustable by the first target reactance device and/or the second target reactance device;

in case the wearable device comprises a first target reactive component, the first target reactive component having a first end and a second end, the first end of the first target reactive component being connected to ground, the second end of the first target reactive component being connected to the first sub-antenna 141;

in case the wearable device comprises a second target reactive component, the second target reactive component has a first end and a second end, the first end of the second target reactive component is connected to ground, the second end of the first target reactive component is connected to the second sub-antenna 142;

in case the wearable device comprises a first target reactive component and a second target reactive component, the first target reactive component has a first end and a second end, the first end of the first target reactive component is connected to ground, the second end of the first target reactive component is connected to the first sub-antenna 141; the second target reactance device has a first end and a second end, the first end of the second target reactance device is grounded, and the second end of the first target reactance device is connected with the second sub-antenna 142.

In this case, the wearable device provided in the embodiment of the present application adjusts the working length of the first sub-antenna 141 and/or the second antenna 142 in the second antenna module 140 only by connecting the reactance device. As described above, the access capacitance is equivalent to making the working length of the antenna longer, and the access inductance is equivalent to making the working length of the antenna shorter. Therefore, the reactive device may be switched in to adjust the working length of the first sub-antenna 141 and/or the second antenna 142 in the second antenna module 140.

As such, the working length of the first sub-antenna 141 can be adjusted only by the accessed first target reactance device; the operating length of the second antenna 142 is adjusted only by switching in a second target reactive device.

Fig. 9 is a schematic view of a wearing belt of another wearing device provided in the embodiments of the present application.

Fig. 10 is a schematic view of a wearing belt of another wearing device provided in the embodiments of the present application.

As shown in fig. 9 to 10, optionally, the wearable device provided in the embodiments of the present application may further include a mode switch assembly 200. One end of the mode switch 200 is connected to the second antenna module 140, and the other end is grounded.

As shown in fig. 9, when the two ends of the mode switch 200 are disconnected, the antenna of the second antenna module 140 is in the form of a Monopole, and the operating mode thereof is a quarter-wavelength Monopole mode, and the operating frequency is f 1; at this time, the switch assembly 150 may change the working length of the second antenna module 140 at the working frequency f1, so as to adjust the directional pattern; when the two ends of the mode switch 200 are connected, the antenna of the second antenna module 140 is a Loop antenna, and the operating mode thereof is Loop mode, the operating frequency is f2, and generally f2 is 2 × f 1; the switching assembly 150 can now achieve a pattern adjustment at the operating frequency f 2.

As shown in fig. 10, when the mode switch 200 is turned off, the antenna is in the form of a T-shaped antenna having three operation modes; when the mode switch 200 is closed, the antenna is in the form of an IFA antenna, having two modes of operation. The working frequency bands of the antenna in different working modes are different, so that the second antenna module 140 can work in five different working frequency bands, and the working frequency bands can be switched by the mode switch 200.

In this way, the mode switch 200 can be used to switch the operating frequency bands of the second antenna module 140, and the switch assembly 150 is used to adjust the directivity pattern, so as to finally adjust the directivity pattern of the second antenna module 140 in multiple operating frequency bands.

The wearing equipment that this application embodiment provided can be for the wrist-watch. When wearing equipment is when the wrist-watch, wearing equipment's wearing main part can be the dial plate, wearing equipment's wearing area can be the watchband. The first antenna module 130 may be disposed inside the watch face, on the surface of the watch face, or at the edge of the watch face, and the second antenna module 140 may be disposed inside the watch band, or on the surface of the watch band. The second antenna module 140 may be disposed on the watch band near the watch face. Optionally, the second antenna module 140 may also be disposed on a connector connecting the watch face and the watch band.

Optionally, when the wearable device provided in the embodiment of the present application is a watch, the watch may further include a third antenna module, and the structure and the form of the third antenna module may be the same as those of the second antenna module. The second antenna module may be disposed on a band of one side of a dial of the watch, and the third antenna module may be disposed on a band of the other side of the dial. The two antenna modules and the third antenna module can work simultaneously or not.

Corresponding to the wearable device provided by the embodiment of the application, the embodiment of the application also provides a control method of the wearable device.

Fig. 11 is a flowchart of a control method of the wearable device according to the embodiment of the present application. The control method of the wearable device shown in fig. 11 can be applied to any wearable device provided in the above embodiments.

As shown in fig. 11, the control method of the wearable device provided in the embodiment of the present application may include the following steps:

step 310, adjusting the phase difference of the antenna array.

Step 320, adjusting the directional diagram of the antenna array by adjusting the phase difference of the antenna array.

It will be appreciated that both the phase and amplitude of the induced field of the antenna have an effect on the antenna pattern, whereas the phase of the antenna pattern of the phase has a greater effect. Therefore, in the control method of the wearable device provided by the embodiment of the application, the directional diagram of the antenna array is adjusted mainly by adjusting the phase difference between the first antenna module and the second antenna module.

In this way, when the phase difference between the first antenna module and the second antenna module is different, the direction of the directional pattern (the direction of the maximum beam) of the antenna array is also different, and the maximum beam of the directional pattern of the antenna array can not be directed to the ground by adjusting the phase difference between the first antenna module and the second antenna module.

The phase difference between the first antenna module and the second antenna module can be adjusted by adjusting the working length of the second antenna module; and changing the phase difference by adjusting the distance between the second antenna module and the first antenna module.

Wearing equipment includes the switch module, the switch module has a first end and a plurality of second end, the switch module first end ground connection, the switch module a plurality of second ends all with the second antenna module is connected. In this case, the adjusting the phase difference of the antenna array may include:

adjusting the working length of the second antenna module by changing the connection state of the first end and the plurality of second ends in the switch assembly; the working length of the second antenna module is the effective length of the second antenna for working; the connection state comprises a conducting state and a disconnecting state;

and adjusting the phase difference by adjusting the working length of the second antenna module.

It is understood that, when a first terminal of the switch component is connected to a second terminal, the connection state of the first terminal and the second terminal is a conducting state; when a first end in the switch assembly is disconnected from a second end, the connection state of the first end and the second end is a disconnection state.

The adjustment of the working length of the second antenna module may be as described above with reference to fig. 2, 4 or 5.

Therefore, the first end of the switch component is connected with different second ends, so that the second antenna module can work at different working lengths, and the length of the second antenna module can be adjusted by adjusting the second end connected with the first end, so as to adjust the phase difference between the first antenna module and the second antenna module.

Meanwhile, the wearable device may further include a switch assembly, which may include a first switch element and/or a second switch element;

when the switch assembly comprises a first switch element, one end of the first switch element is connected with the first sub-antenna, and the other end of the first switch element is grounded;

when the switch assembly comprises a second switch element, one end of the second switch element is connected with the second sub-antenna, and the other end of the second switch element is grounded;

in a case where the switching assembly includes a first switching element and a second switching element, one end of the first switching element is connected to the first sub antenna, and the other end of the first switching element is grounded; one end of the second switch element is connected with the second sub-antenna, and the other end of the second switch element is grounded. In this case, the adjusting the phase difference of the antenna array comprises:

adjusting the distance between the second antenna module and the first antenna module by changing the working state of the first switch element and/or the second switch element;

and changing the phase difference by adjusting the distance between the second antenna module and the first antenna module.

The adjustment of the distance between the second antenna module and the first antenna module may refer to the description above with respect to fig. 6.

In this way, the sub-antenna for operation in the second antenna module can be switched by the first switch element and/or the second switch element. Because the distances between the sub-antennas in the second antenna module and the first antenna module are different, the distances between the second antenna module and the first antenna module can be adjusted by enabling the different sub-antennas to work, and the phase difference can be further adjusted.

It should be understood that the control method of the wearable device described above can be applied to the wearable device provided in the embodiments of the present application.

In the embodiments of the present application, the difference between the embodiments is described in detail, and different optimization features between the embodiments can be combined to form a better embodiment as long as the differences are not contradictory, and further description is omitted here in view of brevity of the text.
