Detailed Description

The following detailed description of specific embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

The terminal described in the embodiment of the present invention may be various types of terminal devices, such as a mobile phone, a tablet computer, a portable computer, a personal digital assistant, and the like, which is not limited in this respect.

The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.

Because the all-metal shell has strong shielding performance on the built-in antenna of the terminal, the existing antenna technology utilizes a part of the metal shell as a radiator of the antenna after the metal shell is cut to form a slot antenna so as to ensure the high radiation efficiency of the antenna. Taking the terminal as an example of a mobile phone, the slot of the metal shell may be a peripheral metal frame around the mobile phone, and specifically, a plurality of slots may be provided according to the design requirement of the antenna, so that the metal frame may include a plurality of side frames, and the lengths of the side frames may be the same or different, which is not specifically limited in the present invention. Of course, the slits may be formed directly in the metal back case, and are not limited herein.

Meanwhile, when the problem of antenna radiation is solved, the metal shell part serving as a radiator is inevitably touched under a hand-held scene, a stronger hand-held weakening effect is caused on the basis of the design of the conventional built-in antenna due to the capacitive effect of the hand, and the hand-held influences of the left hand and the right hand are inconsistent.

In order to solve the above problems, the ASDIV technology may be adopted, that is, the chip may switch the main antenna to the antenna at the top of the mobile phone in a handheld situation according to a usage scenario, so as to avoid the problem that the signal of the bottom antenna is weakened to weaken the signal of the whole antenna. However, because the antenna at the top of the mobile phone has a weak signal receiving function, signal reception still needs to be enhanced through the antenna at the bottom of the mobile phone, and thus, the performance of the antenna is still significantly affected by human hands.

Fig. 1 is a schematic diagram of an internal structure of an antenna provided in an embodiment of the present invention, and as shown in fig. 1, the terminal device includes a metal back shell 100, a radiation main body 111; the radiating body 111 is located in the desired hand-held area of the terminal (e.g., the bottom of the handset).

In the embodiment of the present invention, the radiation main body 111 is taken as the bottom of the metal back shell 100, and the ends of the radiation main body 111 are located at the left and right sides of the terminal, for example, the radiation main body 111 is not connected to the metal back shell 100 through the slot to form a slot antenna for radiating and receiving electromagnetic wave signals, and the metal back shell 100 of the mobile phone can be used as a reference ground of the mobile phone. For example, when the mobile phone is in a horizontal scene and the terminal of the radiation main body 111 contacting with the human hand is located at the top and/or the bottom of the terminal, or when the mobile phone is in a call receiving state, one or more of the terminal of the radiation main body 111 of the terminal, the terminal of the terminal, and the terminal of the radiation main body 111 of the terminal are located at the left and right sides of the terminal, the top and the bottom of the terminal and contact with the human hand and other parts of the human body, reference may be made to this embodiment, and details are not described here.

As shown in fig. 2, in a scenario where the terminal is held by left/right hands, the antenna signal radiation of the area 1 is absorbed heavily by human hands (particularly, the tiger part), and the parts held by the radiation body 111 are different by the left and right hands, resulting in a difference in antenna performance.

As shown in fig. 3, an embodiment of the present invention provides an antenna, where the antenna is located in a bottom frame region of a terminal; the antenna includes: a power feeding unit 300, a radiation body 111, a first control unit 301, and a second control unit 302;

the radiating body 111 includes a feeding point 311 therein; the feeding point 311 is connected to the feeding unit 300 of the antenna;

the first control unit 301 is connected to the first end of the radiating body 111, and is configured to control communication between the first end of the radiating body 111 and a grounding point of the antenna;

the second control unit 302 is connected to the second end of the radiating body 111, and is configured to control communication between the second end of the radiating body 111 and the grounding point of the antenna; the first end and the second end correspond to two ends of the bottom frame respectively.

The feeding unit 300 may be fed from a feeding point 311 on the radiation main body 111, and the selection of the feeding point 311 may be determined according to a specific antenna layout, or may be determined according to a specific antenna adjustment requirement, which is not limited herein. As shown in fig. 4, the feeding unit 300 may include a signal source 32 and a tuning circuit 33 of the signal source 32.

The feed point 311 divides the radiating body 111 into two left and right antenna branches. At the two sides of the antenna branch end slot, a first control unit 301 and a second control unit 302 may be respectively disposed.

In a specific embodiment, the grounding point 331 and 332 of the antenna may be disposed on the metal back shell 100 of the terminal, and the first control unit 301 and the second control unit 302 are respectively connected to the metal back shell 100.

Of course, the grounding point of the antenna may also be arranged inside the terminal, for example, the grounding point of the antenna is arranged on an internal grounding circuit of the terminal, and the first control unit and the second control unit are respectively connected with the internal grounding circuit. The internal ground circuit may be located on the alloy plate inside the terminal, or may be a separately provided ground circuit, which is not limited herein.

As shown in fig. 3, the radiation body 111 is spaced from the grounding point 331-332 by the slit. Of course, other metal areas may be selected as the grounding point of the antenna, which is not limited herein.

In the embodiment of the present invention, the feeding point 311 is disposed at the middle position of the radiation main body 111, and the two ends are grounded, so as to divide the radiation main body 111 of the antenna into two branches, namely, a left branch and a right branch, and form two branches of a full-band antenna in a clearance area at the bottom of the terminal. Each antenna branch can be independently used as an antenna body of a desired operating frequency band in case the other antenna branch is grounded. By grounding the antenna branches of the hand contact area, the radiating body 111 effectively avoids the antenna branch at the position where the human hand absorbs the strongest, thereby eliminating the influence of the human hand on the antenna and realizing the maximization of the radiation efficiency of the antenna.

In the embodiment of the present invention, a plurality of antenna branches may be provided by providing a plurality of feeding points or a plurality of grounding points, the number of the antenna branches may be two or more, and may be determined according to needs.

Due to the characteristics that the antenna performance is obviously influenced by hand holding and the influence of the left hand and the right hand on the antenna performance is different, in the embodiment of the invention, the first control unit 301 and the second control unit 302 can be controlled under the condition that the left hand and the right hand are held, so that the antenna performance is ensured, and meanwhile, the working antenna is switched, so that the negative influence caused by a human body is eliminated.

In one possible implementation, the first control unit 301 includes: a switching circuit connected in parallel; the switching circuit is used to control the communication of the first control unit 301 to the antenna ground point 331.

In one possible implementation, the second control unit 302 includes: parallel switching circuit the switching circuit is used to control the connection of the second control unit 302 to the antenna ground point 332.

The parallel switch circuits can be set as single-pole multi-throw switches; the single-pole multi-throw switch can be provided with a short circuit and a broken circuit shunt, when a hand (such as a tiger mouth) contacts the position corresponding to the antenna branch, the antenna branch is grounded through the short circuit, and the influence of the hand body is eliminated through grounding. In addition, the antenna branch is not used as an antenna radiation main body, and other switches can be added in the antenna branch to be synchronously grounded so as to better eliminate the influence of human hands on the whole antenna.

In order to realize the coverage of the two branch antennas to the required operating frequency band, as shown in fig. 4, the first control unit 301 includes: a switching circuit 35 and a tuning circuit 351 connected in parallel; the switching circuit 35 is used to control the communication of the first control unit 301 to the antenna ground point 331; the tuning circuit 351 is used to adjust the frequency of the antenna.

In one possible implementation, the second control unit 302 includes: a switching circuit 34 and a tuning circuit 342 connected in parallel; the switching circuit 34 is used to control the communication of the second control unit 302 to the antenna ground point 332; the tuning circuit 342 is used to adjust the frequency of the antenna.

The coverage of the two branch antennas to the required working frequency band is realized by arranging the first control unit 301 and the second control unit 302 between the two ends of the radiation main body 111 and the grounding points 331-332, and two full-band antenna branches are formed in the bottom area of the terminal.

In one possible implementation, the tuning circuits 351 and 342 comprise a capacitance and/or an inductance for adjusting the antenna parameters.

In the specific implementation process, the radiation body 111 can be selectively connected to the grounding points 331-332 through a series capacitor or a short circuit. The equivalent ground capacitance of the antenna and the grounding points 331-332 is changed by the parallel capacitance mode, so as to realize the broadband coverage of the antenna.

As shown in fig. 4, the radiating body 111 is divided into two antenna branches on the left and right by a feed point 311. The second control unit 302 has four states of a series capacitor C1, a series capacitor C2, short circuit and open circuit; the first control unit 301 has four states of a series capacitor C3, a series capacitor C4, short circuit and open circuit;

thus, in different states of the control unit, the states of the grounding point of the corresponding antenna may include: the first control unit 301 has four states of series capacitance C1+ C0, C2+ C0, short circuit and C0, and the second control unit 302 has four states of series capacitance C3+ C0, C4+ C0, short circuit and C0. The capacitor C0 is an inherent capacitor formed by the radiation body 111 and the grounding point 331-332 through the slit.

According to the resonance principle: LC (2 pi f) ^2 ═ 1

L is an antenna equivalent inductance, C is an antenna equivalent capacitance, f is an antenna working frequency, and the antenna can resonate in different frequency bands by changing the equivalent capacitance C.

Further, the antenna broadband switching can be realized by adding a parallel capacitor or a circuit break in the first control unit 301 and the second control unit 302.

Specifically, the end of each antenna branch is close to the grounding point 331-332 and has an equivalent capacitor C1, and the end of each antenna branch can be further connected with the grounding point 331-332 by serially connecting different capacitors Cn through switches, and by superimposing C1-Cn between the end of the antenna branch and the grounding point 331-332, the multi-band compatible design is realized.

The embodiment of the invention provides a terminal which comprises any antenna provided by the embodiment of the invention.

Based on the same inventive concept, an embodiment of the present invention provides an antenna adjusting method, which is applicable to a terminal provided by the embodiment of the present invention, and includes:

the terminal determines the holding posture of a user;

the terminal determines the matching working state of the first control unit 301 and the second control unit 302 according to the holding gesture;

the terminal controls the first control unit 301 and the second control unit 302 to be in the matching working state, so that the antenna signal of the terminal is matched with the holding gesture.

In a terminal holding scene, according to the determined holding posture, the holding posture is determined to influence the antenna branch in the radiation main body 111, the influence of the branch on the antenna is reduced by forcibly grounding in a short circuit mode of the antenna branch and the grounding point, meanwhile, the radiation main body is switched to the other end, the switching of the antenna branch is realized, and the higher radiation efficiency is ensured.

The method for judging the holding postures of the left hand and the right hand can determine the holding posture of the terminal according to sensor data received by a sensor in the terminal; or, the antenna chip or the coupling device compares signals of different antenna branches of the antenna to determine the radiation efficiency of the antenna, and then determines the holding posture, which may be determined according to other manners, which is not limited herein.

In one possible implementation, the holding posture is left-handed holding;

the terminal determines the matching working state of the first control unit 301 and the second control unit 302 according to the holding gesture, and the method includes:

the terminal determines that the first control unit 301 is in the open state or the tuning state and the second control unit 302 is in the ground state.

In a left-hand holding scenario, for example, in conjunction with the mobile phone in fig. 2, the area held by a hand has a large influence on the performance of the antenna in the area 1, so that the left antenna branch may be set to be grounded and not operated, as shown in fig. 5, that is, the second control unit 302 is in a grounded state. The right branch of the antenna is used as a radiator of a signal, the first control unit 301 is in an open circuit state, and of course, the first control unit 301 may also select states of different equivalent inductances connected in series in the tuning circuit 35 through a switch, so as to ensure the radiation efficiency of the antenna.

In one possible implementation, the holding posture is right-handed holding;

the terminal determines the matching working state of the first control unit 301 and the second control unit 302 according to the holding gesture, and the method includes:

the terminal determines that the second control unit 302 is in the open state or the tuning state and the first control unit 301 is in the ground state.

In a scene of holding the mobile phone by the right hand, as shown in fig. 6, the antenna performance in the area 2 is greatly affected by the area held by the hand, so that the right antenna branch may be set to be grounded and not operated, that is, the first control unit 301 is in a grounded state. The left branch of the antenna is used as a radiator of a signal, the first control unit 301 is in an open circuit state, and of course, the first control unit 301 may also select states of different equivalent inductances connected in series in the tuning circuit 34 through a switch, thereby ensuring the radiation efficiency of the antenna.

In one possible implementation, the held posture is an unclamped state;

the terminal determines the matching working state of the first control unit 301 and the second control unit 302 according to the holding gesture, and the method includes:

the terminal determines that the first control unit 301 is in the open state or the tuning state and the second control unit 302 is in the open state or the tuning state.

In a situation that the terminal is not held by the hand, as shown in fig. 2, taking a mobile phone as an example, the hand does not affect the performance of the antenna, so that the left and right antenna branches can work simultaneously, the right antenna branch is used as a radiator of a signal, the first control unit 301 and the second control unit 302 are in an open circuit state, and of course, the first control unit 301 and the second control unit 302 can also be connected in series with different equivalent inductances through a switch, so as to ensure the radiation efficiency of the antenna.
