Technical Field

The invention relates to the field of wireless communication, in particular to an antenna for wireless communication and electronic equipment with the antenna.

Background

Currently, the number of antennas is more in 5G communication frequency band, such as sub6GHz NR frequency band, than in 4G LTE. Meanwhile, a full-screen and a curved-surface screen are the mainstream at present, and due to the design requirements of the full-screen and the curved-surface screen, a clearance area and space are smaller and smaller, which is in conflict with the increase of the number of antennas under 5G communication. Currently, in order to meet the requirements of a full-face screen and a curved-face screen, the size of an antenna often has to be reduced, so that the efficiency of the antenna is low, and the bandwidth is narrow. Particularly, for an Ultra Wide Band (UWB) antenna, since the transmission distance of the UWB is usually within 10m and a bandwidth of 1GHz or more is used, the UWB does not use a carrier but uses a nanosecond to picosecond-level non-sinusoidal narrow pulse to transmit data, and thus, the occupied frequency spectrum range is wide, and when the size of the UWB antenna is compressed, the transmission performance of the UWB is greatly affected.

All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

In the description of the embodiments of the present invention, it should be understood that the terms "thickness" and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, and do not imply or indicate that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

Fig. 1 is a schematic plan view of an antenna 1 according to an embodiment of the present application. As shown in fig. 1, the antenna 1 includes an antenna body 10, two first-type through grooves 11 and two second-type through grooves 12 are provided on the antenna body 10, the lengths of the two first-type through grooves 11 are different from the lengths of the two second-type through grooves 12, the two first-type through grooves 11 are used for realizing resonance of a first frequency band, so that the antenna 1 supports transceiving of radio frequency signals of the first frequency band, and the two second-type through grooves 12 are used for realizing resonance of a second frequency band, so that the antenna 1 supports transceiving of radio frequency signals of the second frequency band.

Therefore, in the present application, through the above design, the antenna 1 can use a smaller size to realize the transceiving of the radio frequency signals of two frequency bands, and can effectively improve the performance of the antenna, and meet the size and performance requirements when the space or the clear area of the electronic device is insufficient.

As shown in fig. 1, the two first-type through slots 11 include a first through slot 111 and a second through slot 112, and the first through slot 111 and the second through slot 112 extend from edges of two opposite sides of the antenna body 10 to a middle portion of the antenna body 10. The two second-type through slots 12 include a third through slot 121 and a fourth through slot 122, and the third through slot 121 and the fourth through slot 122 extend from edges of the other two opposite sides of the antenna body 10 to a middle portion of the antenna body.

That is, the openings of the first through groove 111 and the second through groove 112 are located at the edges of two opposite sides of the antenna body 10, and the first through groove 111 and the second through groove 112 extend to positions other than the edges of the antenna body 10. The openings of the third through groove 121 and the fourth through groove 122 are located at the edges of the other two opposite sides of the antenna body 10, and the third through groove 121 and the fourth through groove 122 also extend to the positions other than the edges of the antenna body 10.

In some embodiments, two opposite sides on which the openings of the first through groove 111 and the second through groove 112 are located are two opposite sides of the antenna body 10 along the first direction D1, and the other two opposite sides on which the openings of the third through groove 121 and the fourth through groove 122 are located are two opposite sides of the antenna body 10 along the second direction D2. Wherein the first direction D1 is not parallel to the second direction D2.

Thus, the openings of the first through groove 111 and the second through groove 112 are staggered with the openings of the third through groove 121 and the fourth through groove 122 at the periphery of the antenna body 10. For example, as shown in fig. 1, the opening of the first through groove 111, the opening of the third through groove 121, the opening of the second through groove 112, and the opening of the fourth through groove 122 are sequentially arranged in the counterclockwise direction of the antenna body 10.

Wherein, although two opposite sides on which the openings of the first through groove and the second through groove are located are two opposite sides of the antenna body along the first direction, and the other two opposite sides on which the openings of the third through groove and the fourth through groove are located are two opposite sides of the antenna body along the first direction, the openings of the first through groove and the second through groove do not necessarily need to be symmetrical about the geometric center of the antenna body 10, and the openings of the third through groove and the fourth through groove do not necessarily need to be symmetrical about the geometric center of the antenna body 10, as long as the openings are approximately arranged on the two opposite sides.

In one embodiment, the first direction D1 is perpendicular to the second direction D2, for example, as shown in fig. 1, the first direction D1 is transverse to the viewing angle of fig. 1, and the second direction D2 is longitudinal to the viewing angle of fig. 1. Obviously, in other embodiments, the first direction D1 and the second direction D2 may be other directions as long as the first direction D1 and the second direction D2 are not parallel.

As shown in fig. 1, the first through groove 111, the second through groove 112, the third through groove 121, and the fourth through groove 122 are all semi-closed through grooves opened at the edge of the antenna body 10.

That is, the first through groove 111, the second through groove 112, the third through groove 121, and the fourth through groove 122 do not extend from one side edge of the antenna body 10 to the other side edge. In this application, the lengths of the first through groove 111, the second through groove 112, the third through groove 121, and the fourth through groove 122 are all significantly smaller than the lengths of the antenna body 10 in the extending direction of the first through groove 111, the second through groove 112, the third through groove 121, and the fourth through groove 122.

The antenna body 10 is a plate-shaped body, and the first through groove 111, the second through groove 112, the third through groove 121, and the fourth through groove 122 all penetrate through the antenna body 10 in the thickness direction of the antenna body 10.

That is, in the present application, the term "through groove" means a groove penetrating through the antenna body 10 in a thickness direction of the antenna body 10, and on a plane of the antenna body 10 perpendicular to the thickness of the antenna body 10, the first through groove 111, the second through groove 112, the third through groove 121, and the fourth through groove 122 are semi-closed through grooves having only one opening at an edge of the antenna body 10.

Wherein, the thickness direction of the antenna body 10 is also: and a direction perpendicular to the extending directions of the first through groove 111, the second through groove 112, the third through groove 121, and the fourth through groove 122.

In some embodiments, the difference between the extending directions of the first through groove 111 and the second through groove 112 and the angle of the first direction D1 is smaller than a first preset angle, and the difference between the extending directions of the third through groove 121 and the fourth through groove 122 and the angle of the second direction D2 is smaller than a second preset angle.

The first preset angle and the second preset angle may be 10 degrees, 15 degrees, 20 degrees, or the like, which is smaller than 45 degrees, so that the openings of the first through groove 111 and the second through groove 112 are disposed at the edges of the antenna body along the two opposite sides of the first direction D1; although the openings of the third through groove 121 and the fourth through groove 122 are provided at the edges of the antenna body along the second direction D2 on the opposite sides, the extending direction (groove body extending direction) of the first through groove 111 and the second through groove 112 may be slightly deviated from the first direction D1, and the extending direction (groove body extending direction) of the third through groove 121 and the fourth through groove 122 may be slightly deviated from the second direction D2. The extending directions of the first through groove 111 and the second through groove 112 may be the same or different, and the extending directions of the third through groove 121 and the fourth through groove 122 may also be the same or different. More specific details are set forth in the description below.

As shown in fig. 1, in an embodiment, the extending directions of the first through slot 111 and the second through slot 112 are both parallel to the first direction D1, and the extension lines of the first through slot 121 and the second through slot 122 are collinear and pass through the geometric center C1 of the antenna body 10; the extending directions of the third through slot 121 and the fourth through slot 122 are both parallel to the second direction D2, and the extension lines of the third through slot 121 and the fourth through slot 122 are collinear and pass through the geometric center C1 of the antenna body 10.

As shown in fig. 1, in an embodiment, the first direction D1 and the second direction D2 are perpendicular. Since the lengths of the first through groove 111, the second through groove 112, the third through groove 121 and the fourth through groove 122 are all significantly smaller than the lengths of the antenna body 10 in the extending direction of the first through groove 111, the second through groove 112, the third through groove 121 and the fourth through groove 122, the first through groove 111, the second through groove 112, the third through groove 121 and the fourth through groove 122 form a "+" shaped structure with the middle part removed.

Further, the lengths of the first through groove 111 and the second through groove 112 may be the same, and the lengths of the third through groove 121 and the fourth through groove 122 may also be the same. Thus, the first through groove 111 and the second through groove 112 are symmetrically disposed on two opposite sides of the antenna body 10, and the third through groove 121 and the fourth through groove 122 are symmetrically disposed on the other two opposite sides of the antenna body 10.

Obviously, the lengths of the first through groove 111 and the second through groove 112 may be different, and the lengths of the third through groove 121 and the fourth through groove 122 may be different.

Fig. 2 is a schematic plan view of an antenna 1 according to another embodiment of the present application. As shown in fig. 2, in another embodiment, the extending directions of the first through groove 111 and the second through groove 112 are not parallel, and the extending directions of the third through groove 121 and the fourth through groove 122 are not parallel. For example, as shown in fig. 2, an included angle between the extending direction of the first through groove 111 and the first direction D1 is smaller than a first preset angle, and an included angle between the extending direction of the third through groove 121 and the second direction D2 is smaller than a second preset angle.

When the extending directions of the first through groove 111 and the second through groove 112 are not parallel, the lengths of the first through groove 111 and the second through groove 112 may be the same or different, and when the extending directions of the third through groove 121 and the fourth through groove 122 are not parallel, the lengths of the third through groove 121 and the fourth through groove 122 may also be the same or different.

That is, the first through groove 111 and the second through groove 11 may be asymmetrically disposed, and the third through groove 121 and the fourth through groove 122 may also be asymmetrically disposed.

Obviously, the extending directions of the first through groove 111 and the second through groove 112 may have an included angle smaller than a first preset angle with the first direction D1, and the extending directions of the third through groove 121 and the fourth through groove 122 may also have an included angle smaller than a second preset angle with the second direction D2.

Wherein, as shown in fig. 1 and 2, in some embodiments, a feeding point F1 is provided in a target region Z1 surrounded by the first through groove 111, the second through groove 112, the third through groove 121, and the fourth through groove 122 away from the respective open ends P1.

That is, in some embodiments, the feeding point F1 for connecting with a feed source to access a feeding signal is disposed in a target region Z1 of the antenna body 10 surrounded by end portions P1 of the respective through slots away from the respective openings.

Wherein the feeding point F1 is disposed at a position offset from the geometric center C1 of the antenna body 10 in the target zone Z1.

As shown in fig. 1 and 2, the target zone Z1 is a zone surrounding the geometric center C1 of the antenna body 10. The feeding point F1 is disposed in the target zone Z1 of the antenna body 10, but at a position offset from the geometric center C1 of the antenna body 10.

In some embodiments, a rectangular coordinate system is established with the geometric center C1 of the antenna body 10 in fig. 1 as the origin of coordinates, the first through slot 111 as the X-axis negative axis, the second through slot 112 as the X-axis positive axis, the third through slot 121 as the Y-axis positive axis, and the fourth through slot 122 as the Y-axis negative axis, and the coordinate position of the feeding point F1 may be (1, 0.6) in mm (millimeters). That is, in the view shown in fig. 1, the feeding point F1 is located at a position shifted 1mm to the right and 0.6mm to the upper from the geometric center C1 of the antenna body 10.

In the present application, the lengths of the two first-type through slots 11 are greater than the lengths of the two second-type through slots 12, and the resonant center frequency of the first frequency band is lower than the resonant center frequency of the second frequency band. That is, in the present application, the length of any one of the first through groove 111 and the second through groove 112 is greater than the length of any one of the third through groove 121 and the fourth through groove 122; the first through groove 111 and the second through groove 112 with longer lengths realize a resonant center frequency of the first frequency band lower than the resonant center frequency of the second frequency band realized by the third through groove 121 and the fourth through groove 122 with shorter lengths.

In some embodiments, the first frequency band is a low frequency band and the second frequency band is a high frequency band.

In some embodiments, at least one of the two first-type through slots 11 has a length of 3.53mm, and at least one of the two second-type through slots 12 has a length of 2.53 mm. For example, when the lengths of the first through groove 111 and the second through groove 112 are the same, the lengths of the first through groove 111 and the second through groove 112 are both 3.53mm, and when the lengths of the third through groove 121 and the fourth through groove 122 are the same, the lengths of the third through groove 121 and the fourth through groove 122 are both 2.53 mm.

Obviously, in other embodiments, the lengths of the two first-type through slots 11 and the lengths of the two second-type through slots 12 may have other suitable values, as long as the lengths of the two first-type through slots 11 are greater than the lengths of the two second-type through slots 12.

As shown in fig. 1 and 2, the antenna body 10 is a circular plate, i.e., a circular cake.

In one embodiment, the radius of the antenna body 10 is 4.5 mm. For example, for the embodiment of fig. 1, the radius of the antenna body 10 is 4.5mm, the first through groove 111 and the second through groove 112 are symmetrically arranged, and both the lengths are 3.53mm, and the third through groove 121 and the fourth through groove 122 are also symmetrically arranged, and both the lengths are 2.53 mm.

Fig. 3 is a schematic plan view of an antenna 1 according to still another embodiment of the present application. In another embodiment, the antenna body 10 is a square plate.

That is, the antenna body 10 may be square.

Wherein, in some embodiments, when the antenna body 10 is a square plate, the length or width of the antenna body is 4.5 mm. Correspondingly, at least one of the two first-type through grooves 11 is 3.53mm in length, and at least one of the two second-type through grooves 12 is 2.53mm in length.

When the antenna body 10 is a square plate, the first direction is a direction parallel to two opposite sides of the antenna body 10, and the second direction is a direction parallel to two other opposite sides of the antenna body 10.

Obviously, in other embodiments, the antenna body 10 may also be a plate body with other shapes, for example, an oval plate body, and so on.

The shape of the antenna body 10 in the present application refers to a shape of a projection of the antenna body 10 in a thickness direction of the antenna body 10.

Wherein, in this application, antenna 1 is UWB (Ultra wide band) patch antenna, the resonance center frequency of the first frequency channel that first logical groove 111 and second logical groove 112 realized is 6.5GHZ, the resonance center frequency of the second frequency channel that third logical groove 121 and fourth logical groove 122 realized is 8GHZ, because UWB's working frequency range is from 3.1GHZ to 10.6GHZ, minimum working bandwidth is 500 MHz. Currently, the center frequencies of the mainstream UWB frequency bands are respectively 6.5GHz and 8GHz, so that the antenna 1 of the present application can support two mainstream UWB frequency bands.

Fig. 4 is a diagram of a current distribution diagram of the antenna 1 operating in the 6.5GHZ band according to an embodiment of the present application. Wherein the current profile is illustrated with the antenna structure shown in fig. 1.

As can be seen from fig. 4, the current of 6.5GHz is distributed significantly more in the first through slot 111 and the second through slot 112 with longer lengths, and the current of 6.5GHz is mainly distributed in the two long slits of the first through slot 111 and the second through slot 112.

Fig. 5 is a diagram illustrating a current distribution when the antenna 1 operates in the 8GHZ band according to an embodiment of the present invention. Wherein the current distribution diagram is also illustrated with the antenna structure shown in fig. 1.

As can be seen from fig. 5, the current of 8GHz is distributed significantly more in the third through slot 121 and the fourth through slot 122 with shorter lengths, and the current of 8GHz is mainly distributed in the two short slits of the third through slot 121 and the fourth through slot 122 with longer lengths.

In the present application, as a whole, the current path is extended by opening the slit at the edge of the antenna body 10 and by the above-mentioned unique opening manner, so that the antenna size can be reduced and the antenna performance can be maintained or improved.

As shown in fig. 4-5, in the present application, the antenna 1 may further include an antenna substrate 20, and the antenna body 10 of the present application is supported on the antenna substrate 20. Obviously, the antenna substrate 20 may be a circuit board or the like in an electronic device on which the antenna 1 is mounted, and may not belong to the structure of the antenna 1.

In order to describe the influence of the two first-type through grooves 11, i.e., the first through groove 111 and the second through groove 112, on lower frequency bands, i.e., 6.5GHZ, and to describe the influence of the two second-type through grooves 12, i.e., the third through groove 121 and the fourth through groove 122, on higher frequency bands, i.e., 8GHZ, simulation tests are performed.

Please refer to fig. 6, which is a schematic diagram illustrating a change of a resonant center frequency of an antenna when a length of a second type of through slot is fixed and a length of a first type of through slot is changed according to an embodiment of the present disclosure.

It is noted that, assuming that the lengths of the first through groove 111 and the second through groove 112 are equal and L1, when the lengths of the two second-type through grooves 12, i.e., the third through groove 121 and the fourth through groove 122, are fixed and the lengths L1 of the two first-type through grooves 11, i.e., the first through groove 111 and the second through groove 112, are changed, as can be seen from fig. 6, the S parameter of the low frequency band is greatly changed, and particularly, the corresponding frequency is greatly changed when the amplitude of the return loss parameter in the S parameter is maximum. Namely, the resonance center frequency of the low frequency band is obviously changed greatly, and the resonance center frequency of the high frequency band is basically not changed.

For example, as shown in fig. 6, when the length of the second type through groove 12 is maintained, when the length L1 of the first type through groove 11 is 3.2mm, the resonance center frequency of the corresponding resonance waveform F11 in the low frequency band is about 7.05GHZ, when the length L1 of the first type through groove 11 is 3.35mm, the resonance center frequency of the corresponding resonance waveform F12 in the low frequency band is about 6.85GHZ, and when the length L1 of the first type through groove 11 is 3.53mm, the resonance center frequency of the corresponding resonance waveform F13 in the low frequency band is about 6.55 GHZ. And the resonance center frequency in the high frequency band is basically maintained to be about 8 GHZ.

Accordingly, it can be seen that the first through groove 111 and the second through groove 112 function as a resonance for a low frequency band such as 6.5 GHZ.

Fig. 7 is a schematic diagram illustrating a change of a resonant center frequency of an antenna when a length of a first type of through slot is fixed and a length of a second type of through slot is changed according to an embodiment of the present application.

It is noted that, assuming that the lengths of the two second-type through grooves 12 of the third through groove 121 and the fourth through groove 122 are equal and L2, when the lengths of the two first-type through grooves 11 of the first through groove 111 and the second through groove 112 are fixed and the lengths L2 of the two second-type through grooves 12 of the third through groove 121 and the fourth through groove 122 are changed, as can be seen from fig. 7, the S parameter in the high frequency band is greatly changed, and particularly, the corresponding frequency is greatly changed when the amplitude of the return loss parameter in the S parameter is maximum. That is, the resonance center frequency of the high frequency band is significantly changed, while the resonance center frequency of the low frequency band is not substantially changed.

For example, as shown in fig. 7, when the length of the first type through groove 11 is maintained, when the length L2 of the second type through groove 12 is 2.53mm, the resonance center frequency of the corresponding resonance waveform F21 in the high frequency band is about 8GHZ, when the length L2 of the second type through groove 12 is 2.7mm, the resonance center frequency of the corresponding resonance waveform F22 in the high frequency band is about 7.75GHZ, and when the length L2 of the second type through groove 12 is 2.9mm, the resonance center frequency of the corresponding resonance waveform F23 in the high frequency band is about 7.5 GHZ. And the resonance center frequency in the low frequency band is basically maintained to be about 6.5 GHz.

Accordingly, it can be seen that the third through groove 121 and the fourth through groove 122 function as a resonance for a high frequency band such as 8 GHZ.

Therefore, in the present application, before shipping, the lengths of the first through groove 111 and the second through groove 112 may be changed as needed to realize resonance in different low frequency bands, and the lengths of the third through groove 121 and the fourth through groove 122 may be changed as needed to realize resonance in different high frequency bands.

Fig. 8 is a schematic plan view of an antenna 1 according to another embodiment of the present application. In other embodiments, the first through groove 111, the second through groove 112, the third through groove 121, and the fourth through groove 122 are further communicated with an end through groove T1 away from the end P1 of each opening, and the extending direction of the end through groove T1 is perpendicular to the extending direction of the corresponding communicated first through groove 111, second through groove 112, third through groove 121, and fourth through groove 122.

Specifically, the first through groove 111, the second through groove 112, the third through groove 121, and the fourth through groove 122 are communicated with the middle portion of the corresponding end through groove T1 away from the end P1 where each of the first through groove 111, the second through groove 112, the third through groove 121, and the fourth through groove 122 are respectively formed into a T-shaped through groove together with the end through groove T1 which each of the first through groove 111, the second through groove 112, the third through groove 121, and the fourth through groove 122 is communicated with.

The current length of the antenna 1 can be further increased by forming the T-shaped through groove in the antenna body 10, so that the performance of the antenna is improved.

Obviously, in some embodiments, the first through slot 111, the second through slot 112, the third through slot 121 and the fourth through slot 122 away from the end P1 of the respective opening may also communicate with the end portion of the corresponding end through slot T1, and the first through slot 111, the second through slot 112, the third through slot 121 and the fourth through slot 122 together with the respective communicating end through slot T1 respectively constitute an L-shaped through slot.

The lengths of the end through slots T1, which are respectively communicated away from the end P1 of the respective openings, of the first through slot 111, the second through slot 112, the third through slot 121 and the fourth through slot 122 may be the same or different.

In some embodiments, the lengths of the end through slots T1, through which the first through slot 111, the second through slot 112, the third through slot 121 and the fourth through slot 122 communicate respectively away from the end P1 of the respective openings, may be in a preset proportional relationship with the lengths of the first through slot 111, the second through slot 112, the third through slot 121 and the fourth through slot 122. For example, each end through slot T1 may be 60% of the length of the first through slot 111, the second through slot 112, the third through slot 121, and the fourth through slot 122 in communication therewith, and so on.

In some embodiments, the lengths of the end through slots T1 connected by the first and second through slots 111, 112 are in the same proportional relationship and in a first proportional relationship with the lengths of the first and second through slots 111, 112, and the lengths of the end through slots T1 of the third and fourth through slots 121, 122 are in the same proportional relationship and in a second proportional relationship with the lengths of the third and fourth through slots 121, 122, the first proportional relationship being different from the second proportional relationship. For example, the first proportional relationship is 60%, the second proportional relationship is 70%, and so on.

Therefore, in the present application, by providing the antenna 1, the antenna performance requirement can be satisfied with a smaller size than that of the conventional antenna, and even the antenna performance can be improved.

The widths of the first through groove 111, the second through groove 112, the third through groove 121, the fourth through groove 122 and the end through groove T1 in the present application may be substantially smaller than the lengths of the first through groove 111, the second through groove 112, the third through groove 121, the fourth through groove 122 and the end through groove T1 in the extending direction. For example, the widths of the first through groove 111, the second through groove 112, the third through groove 121, the fourth through groove 122 and the end through groove T1 may be 1/10 and the like of the lengths of the first through groove 111, the second through groove 112, the third through groove 121, the fourth through groove 122 and the end through groove T1 in the extending direction, respectively; the widths of the first through groove 111, the second through groove 112, the third through groove 121, the fourth through groove 122, and the end through groove T1 are not particularly limited in the present application. The widths of the first through groove 111, the second through groove 112, the third through groove 121, the fourth through groove 122 and the end through groove T1 refer to: the dimension in the direction perpendicular to the longitudinal direction (i.e., the extending direction) in which the first through groove 111, the second through groove 112, the third through groove 121, the fourth through groove 122, and the end portion through groove T1 extend and the thickness direction of the antenna body 10.

The antenna body 10 is made of a metal material or a conductive alloy, for example, a material such as copper, silver, iron, or a copper-silver alloy, a copper-iron alloy, or the like.
