Referring to fig. 1 and 2, schematic diagrams of a conventional dual-band dual-polarized antenna module are shown. As shown in fig. 1 and fig. 2, to implement a dual-frequency design, the antenna module may include two antenna radiation plates 1, and the two radiation plates 1 may adopt a stacked structure as shown in fig. 1 or fig. 2. Based on the laminated structure, the dual-frequency can be realized through laminated coupling, and the realization of dual-polarization design can be supported. In addition, the antenna radiation piece 1 is connected with a feed probe 2 perpendicular to the antenna radiation piece 1 in the manner shown in fig. 1 or fig. 2, so that a dual-polarized design can be realized. However, the stacked structure makes the antenna module thicker, and thus the electronic device is thicker.

Referring to fig. 3, the conventional design generally adopts an Antenna In Package (AIP) technology, an array Antenna is composed of a plurality of conventional dual-band dual-polarized Antenna modules, the array Antenna and components in the electronic device (such as the rf integrated circuit 3 and the integrated power management circuit 4 shown in fig. 3) are packaged in one module, and the packaged module is installed in the electronic device, and the mounting position of the packaged module in the electronic device and the connection relationship with other components in the electronic device refer to fig. 4. Each of the antenna radiation pieces 1 shown in fig. 3 and 4 is the antenna radiation piece exposed to the outside in the corresponding stacked structure, which is not shown in fig. 3 and 4. It can be seen that this design also results in a thicker electronic device.

Different from the above design method of the conventional dual-frequency dual-polarized antenna module, please refer to fig. 5 to 7, fig. 19 to 20, and fig. 22 to 23, an embodiment of the present invention provides a dual-frequency dual-polarized antenna module, which includes an antenna radiation sheet 1 and two feeding probes 2.

In this embodiment, the antenna radiation sheet 1 is provided with at least two slots 5, and the antenna radiation sheet 1 is axisymmetric with respect to a first symmetry axis and a second symmetry axis, respectively, where the first symmetry axis is perpendicular to the second symmetry axis, and a length of the first symmetry axis on the antenna radiation sheet 1 is equal to a length of the second symmetry axis on the antenna radiation sheet 1.

In this embodiment, the slot 5 is formed in the radiation sheet body of the antenna radiation sheet 1, so that, for the radiation sheet body, the slot 5 can be provided with a current path, and a frequency band can be additionally generated, thereby achieving the purpose of dual-frequency.

Based on this, the dual-band dual-polarized antenna module provided by this embodiment can cover the existing 5G millimeter wave frequency band, for example, the 5G millimeter wave frequency band that can be covered includes n258(24.25GHz-27.5GHz), n257(26.5GHz-29.5GHz), n261(27.5GHz-28.35GHz), n260(37.0GHz-40.0GHz), n259(39.5GHz-43.5GHz), and other millimeter wave frequency bands defined later by the 3GPP (third generation partnership project).

In this embodiment, the first axis of symmetry and the second axis of symmetry are perpendicular and equal in length on the antenna radiation patch 1. First, the radiating patch body is axisymmetric about the first symmetry axis and the second symmetry axis, respectively, so that this symmetric structure of the radiating patch body can support a dual polarization design. Furthermore, the slots 5 which are provided are likewise of axisymmetric design with respect to the first and second axes of symmetry, respectively, so that this symmetrical structure of the slots 5 can also support a dual-polarization design. In this way, the antenna radiation piece 1 is axisymmetric with respect to the first symmetry axis and the second symmetry axis, respectively, so that the radiation piece as a whole can support dual polarization design.

Referring to fig. 5 to 6, fig. 5 may be a top view of an antenna module, fig. 6 may be a front view of the antenna module, and fig. 7 may be a perspective view of the antenna module. As shown in fig. 5 and 7, the outline of the antenna radiation sheet 1 may be preferably square. The first axis of symmetry and the second axis of symmetry may be respectively as indicated by the two dashed lines in fig. 5.

It can be seen that the first symmetry axis and the second symmetry axis are perpendicular, and the lengths on the antenna radiation piece 1 are equal, and the square antenna radiation piece body is axisymmetric respectively about both symmetry axes. In addition, the intersection of each axis of symmetry with a side of the square is at an angle of 90 °, i.e., each axis of symmetry is perpendicular to two corresponding sides of the square and parallel to the other two sides.

Based on this, the at least two slits 5 may be an upper slit and a lower slit as shown in fig. 5, a left slit and a right slit as shown in fig. 5, or four slits as shown in fig. 5. When the slots are arranged in this way, the antenna radiation pieces 1 can be supported to be axially symmetrical about the two symmetrical axes respectively so as to keep a symmetrical structure, and therefore, a dual-polarization design can be supported.

Based on this, in one embodiment of the present disclosure, the antenna radiation sheet 1 is provided with four slots 5; the four slots 5 correspond to the 4 edges of the antenna radiation sheet 1 one by one; the slots 5 comprise first slots extending along the length of the respective sides.

As shown in fig. 5 and 7, four slots 5 are respectively disposed at adjacent positions of four sides of the square, so that the four slots 5 correspond to the 4 sides of the antenna radiation piece 1 one by one, and each slot 5 is a slot (i.e., a first slot) extending along the length direction of the corresponding side.

In this embodiment, for the two feeding probes 2, one feeding probe 2 is disposed at a position corresponding to a first symmetry axis of the antenna radiation piece 1, the other feeding probe 2 is disposed at a position corresponding to a second symmetry axis of the antenna radiation piece 1, and the two feeding probes 2 are disposed at a position deviated from a center position of the antenna radiation piece 1, where the center position is a position corresponding to an intersection point of the first symmetry axis and the second symmetry axis.

As shown in fig. 5 and 7, one of the two feed probes 2 is disposed at a position corresponding to the first axis of symmetry of the antenna radiation piece 1, and the other is disposed at a position corresponding to the second axis of symmetry of the antenna radiation piece 1. But neither of the two setting positions is at the center position of the antenna radiation piece 1, which is the intersection position of the two symmetry axes, because the impedance at this position does not satisfy 50 ohms.

By arranging the two feed probes 2 on two perpendicular coordinate axes, respectively, one feed probe 2 can generate horizontal polarization, and the other feed probe 2 can generate vertical polarization, thereby realizing dual-polarization design.

In an embodiment of the present disclosure, taking the antenna radiation sheet 1 shown in fig. 5 as an example, by testing an antenna module including the antenna radiation sheet 1, a corresponding S parameter (as shown in fig. 8) can be obtained. Referring to fig. 8, the antenna module generates three resonances, which are resonance 1, resonance 2, and resonance 3 shown in fig. 8. Of these,

resonances

1 and 3 are useful resonances, while resonance 2 is a spurious one, and is an unusable resonance, which has a low antenna efficiency.

As shown in fig. 8, the

resonances

1 and 3 correspond to two frequency bands, respectively, i.e., the antenna module can cover dual frequencies. In addition, by changing one or more of the side length, the slot length and the slot width of the square according to needs, the dual-frequency coverage effect can be adjusted correspondingly, and the specific adjustment effect is as follows.

Experimental studies have found that by adjusting the length of the slot 5, the frequency offset of the resonance 3 can be controlled. Wherein the longer the length of the slot 5, the lower the frequency shift of the resonance 3, and the shorter the length of the slot 5, the higher the frequency shift of the resonance 3.

Experimental studies have found that by adjusting the width of the slot 5, the impedance matching of the resonance 3 can be adjusted, and the S-parameter of the resonance 3 is optimized.

Experimental research shows that the frequency offset of the resonance 1 can be adjusted by adjusting the side length of the antenna radiation sheet 1. Wherein, the longer the side length of the antenna radiation sheet 1, the lower the resonance 1 shifts, and the shorter the side length of the antenna radiation sheet 1, the higher the resonance 1 shifts.

As mentioned above,

resonances

1 and 3 are useful resonances. Fig. 9 to 18 show the frequency patterns of the partial frequency points of resonance 1 and resonance 3. The directional diagram is a graph of the distribution of the radiation electromagnetic field of the antenna along with the angular coordinate at a fixed distance.

Fig. 9 is a 3D directional diagram of the antenna module corresponding to 24GHz, and fig. 10 is a 2D directional diagram of the antenna module corresponding to 24 GHz; fig. 11 is a 3D directional diagram of the antenna module corresponding to 25GHz, and fig. 12 is a 2D directional diagram of the antenna module corresponding to 25 GHz; fig. 13 is a 3D directional diagram of the antenna module corresponding to 35GHz, and fig. 14 is a 2D directional diagram of the antenna module corresponding to 35 GHz; fig. 15 is a 3D directional diagram of the antenna module corresponding to 40.5GHz, and fig. 16 is a 2D directional diagram of the antenna module corresponding to 40.5 GHz; fig. 17 is a 3D directional diagram of the antenna module corresponding to 41GHz, and fig. 18 is a 2D directional diagram of the antenna module corresponding to 41 GHz. Based on these patterns, it can be seen that

resonances

1 and 3 can produce the same pattern as the patch antenna.

Based on the above, it can be seen that, by slotting on the antenna radiation piece, the antenna module provided by this embodiment can generate dual frequencies, and based on the symmetrical structure of the antenna radiation piece and the arrangement positions of the two feed probes on the symmetry axis of the antenna radiation piece, the antenna module provided by this embodiment can generate dual polarizations. Specifically, the antenna module may cover n258(24.25GHz-27.5GHz)/n261(27.5GHz-28.35GHz)/n257(26.5GHz-29.5GHz) and n259(39.5GHz-43.5GHz)/n260(37GHz-40GHz), that is, may cover dual bands in a millimeter wave band defined by 3GPP, and may also be other band combinations, which is not limited herein.

As can be seen from fig. 1 to fig. 4 in combination with the above description, the conventional dual-band dual-polarized antenna module adopts a stacked structure to implement dual-band, but the design manner of implementing dual-band design by stacked coupling results in a thicker antenna thickness, and thus a thicker thickness of electronic devices such as mobile phones and other mobile terminals.

The dual-frequency antenna is realized by arranging the slot 5 on the antenna radiation piece 1, and dual-polarization is realized based on the symmetrical structure of the antenna radiation piece and the arrangement positions of the two feed probes on the symmetrical axis of the antenna radiation piece, so that the dual-frequency antenna does not need to be realized by adopting a laminated structure, the dual-frequency antenna can be realized under the condition that the thickness and the area of the antenna are not increased, and the dual-polarization realization can be supported, thereby the extremely-caused appearance requirements of smaller size and light weight of electronic equipment can be met.

Therefore, the embodiment of the application provides a dual-frequency dual-polarized antenna module, which is based on the antenna radiation piece provided with the slot to realize dual-frequency, and based on the symmetrical structure of the antenna radiation piece and the arrangement positions of the two feed probes on the symmetry axis of the antenna radiation piece respectively to realize dual-polarization, so that the dual-frequency can be realized without adopting a laminated structure in the design of the antenna structure, and dual-polarization can be realized based on the structure, and the thickness of the dual-frequency dual-polarized antenna is not thick.

In an embodiment of the present disclosure, as shown in fig. 5 to 7, the dual-frequency dual-polarized antenna module further includes: a floor 6, a medium 7 filled between the antenna radiation sheet 1 and the floor 6; the floor 6 is provided with a hole corresponding to the feed probe 2; the feed probe 2 penetrates through the medium 7, one end of the feed probe 2 is connected with the antenna radiation sheet 1, and the other end of the feed probe 2 penetrates through a hole, corresponding to the feed probe 2, of the floor 6.

As shown in fig. 5 and 7, the size of the floor 6 is larger than that of the antenna radiation piece 1, the medium 7 is located between the floor 6 and the antenna radiation piece 1, and the size of the medium 7 matches with that of the floor 6. The feed probe 2 penetrates through the medium 7, one end of the feed probe is connected with the antenna radiation sheet 1, and the other end of the feed probe penetrates through a hole, corresponding to the feed probe 2, of the floor 6. The medium 7 is not shown in fig. 6.

In this embodiment, the floor 6 is used for carrying the antenna radiation sheet 1.

Alternatively, the floor 6 may be a metal floor.

Alternatively, the floor may be a Liquid Crystal Polymer (LCP), or other low dielectric constant, low loss dielectric material.

As mentioned above, the side length, the slot length and the slot width of the square radiation sheet body can be adjusted to adjust the dual-frequency coverage effect accordingly. In addition, the present embodiment provides another adjustment manner, that is, the shape of the outline of the antenna radiation sheet 1 is adjusted, so as to adjust the dual-frequency coverage effect accordingly.

Based on this, in an embodiment of the present disclosure, as shown in fig. 19 and 20, the outline of the antenna radiation sheet 1 is a square with notches at four corners; wherein, the notch is a square notch with a set side length.

Referring to fig. 19, the square notch can be shown as a square dashed line in fig. 19.

Referring to fig. 19 and 20, fig. 19 may be a top view of the antenna module provided in the present embodiment, fig. 20 may be a perspective view of the antenna module, and a front view of the antenna module may be as shown in fig. 6.

Except that the notches are disposed at the four corners of the square, the antenna module provided in this embodiment may have no difference from the antenna module shown in fig. 5.

In an embodiment of the present disclosure, taking the antenna radiation sheet 1 shown in fig. 19 as an example, by testing an antenna module including the antenna radiation sheet 1, a corresponding S parameter (shown as a curve corresponding to S2 in fig. 21) can be obtained. In fig. 21, the S parameter of the comparison antenna module (shown as the curve corresponding to S1 in fig. 21) is also shown. The other features of the two antenna modules are consistent except that the outline of the antenna radiation sheet 1 in the antenna module of the comparison group is square (i.e. the notch is not provided).

Referring to fig. 21, it can be seen by comparing the S parameters corresponding to the set notch and the non-set notch that the impedance matching of the resonator 3 in the S parameters of the antenna module can be adjusted by cutting off the square notch at each of the four corners of the square, and the bandwidth of the resonator 3 can be increased, and the frequency offset of the resonator 1 can be adjusted.

In addition to the above mentioned adjustment for providing the notch, the present embodiment also provides another adjustment for adjusting the shape of the slot 5, so as to adjust the dual-frequency coverage effect accordingly.

Based on this, in an embodiment of the present disclosure, as shown in fig. 22 and 23, the slot 5 further includes: two second slits extending from both ends of the first slit in a set direction, respectively; the set direction is perpendicular to the length direction. That is, the slit 5 may be a slit having a cross section similar to a U shape as shown in fig. 22 and 23.

As shown in fig. 22 and 23, the notch of the U-shaped slot faces the center position of the antenna radiation piece 1, that is, the notch of the U-shaped slot faces the feeding point. As such, in one embodiment of the present disclosure, the notch of the slot 5 is toward the center of the antenna radiation piece 1.

Based on different practical application requirements, in other embodiments of the present disclosure, the notch of the slot 5 may also be defined to be away from the central position of the antenna radiation piece 1, that is, the notch of the U-shaped slot is away from the feeding point.

As shown in fig. 22 and 23, this embodiment provides an antenna module, which is designed to provide a notch (shown by a dotted line in fig. 22) at the same time of providing the U-shaped slot. Wherein fig. 22 shows a top view of the antenna module, fig. 23 shows a perspective view of the antenna module, and a front view of the antenna module can be seen in fig. 6.

In other embodiments of the present disclosure, the antenna module may be provided with only the U-shaped slot without the notch.

Experimental studies have found that by changing the shape of the slot shown in fig. 5 (i.e., the cross section of the slot is linear) to the shape of the slot shown in fig. 22 (i.e., the cross section of the slot is U-shaped), the frequency offset of the resonance 3 in the S-parameter can be further adjusted, so that the resonance 3 is shifted to a low frequency.

By last knowing, the antenna module that this embodiment provided is through setting up the slot and in order to realize the dual-frenquency, the symmetrical structure based on antenna radiation piece and the specific position that sets up of two antenna radiation pieces are in order to realize the dual polarization, thereby can realize dual-frenquency dual polarization purpose under the condition that does not additionally increase antenna thickness and antenna area, not only reduce electronic equipment's thickness, still can reduce the input cost, save the space that the antenna occupy, satisfy the extremely needs that send the outward appearance of electronic equipment, promote user's use and experience, good using value has in practical application.

As shown in fig. 24 and 25, an embodiment of the present disclosure also provides an antenna apparatus, including: at least two dual-frequency dual-polarized antenna modules provided by any of the above embodiments of the present disclosure, a transmission line 8 and a first connector 9. Wherein, the floors 6 included by the adjacent antenna modules are connected; one end of the transmission line 8 is connected with the floor 6, and the other end of the transmission line is connected with the first connector 9; the first connector 9 is used to connect a second connector included in an external main board 10.

In this embodiment, two or more antenna modules form an antenna array (as shown by the antenna modules in the dashed line frame in fig. 24 and fig. 25), for example, the number of the antenna modules may be any realizable number, such as 3, 4, 5, and the like. The antenna modules may be connected end to end in sequence as shown in fig. 24, or may be arranged in a matrix as shown in fig. 25.

In this embodiment, the adjacent antenna modules include the floor boards 6 connected to each other, and the floor boards 6 are connected to the first connectors through the transmission lines 8.

Alternatively, the transmission line 8 may be a Flexible Printed Circuit (FPC), and the material of the FPC may be a Liquid Crystal Polymer (LCP), MPI, or other low loss material. Wherein, MPI is Modified PI, which is a polyimide antenna with an improved formula, and MPI is a non-crystalline material.

Alternatively, the first connector may be a BTB (board to board) connector. The first connector may be disposed on the transmission line 8 by Surface Mounted Technology (SMT). The first connector is used for connecting with a corresponding connector on the mainboard.

The antenna device provided by the embodiment can be placed in electronic equipment such as mobile phones and other mobile terminals, and the first connector of the antenna device is connected with the corresponding connector of the main board in the electronic equipment.

Based on the above, as shown in fig. 26, an embodiment of the present disclosure further provides an electronic device, including: the present disclosure provides an antenna device according to any of the above embodiments, and a main board 10 including the second connector.

As shown in fig. 26, the electronic device includes an antenna device, the antenna device includes 4 antenna modules, and the arrangement of the antenna modules is as shown in fig. 24.

In this embodiment, the first connector 9 of the antenna device is connected to the second connector. In this way, the connection of the antenna device to the main board 10 can be realized.

In this embodiment, the floor 6 of the antenna device is disposed adjacent to the main board 10 than the antenna radiation sheet 1 of the antenna device, and the floor 6 is disposed parallel to the main board 10.

Since antenna radiation piece 1 needs to emit a millimeter wave signal outward, floor 6 is closer to main board 10 than antenna radiation piece 1. In order to avoid increasing the thickness of the electronic device, the floor panel 6 may be arranged parallel to the main board 10.

In this embodiment, the first connector 9, the second connector and the floor 6 are horizontally arranged and are respectively arranged on the same side of the main board 10.

The first connector 9 of the antenna device is connected to a second connector (not shown in fig. 26) of the main board 10, and for facilitating the connection between the two, the two connectors are preferably located on the same side of the main board 10 and arranged in a horizontal manner.

To avoid increasing the thickness of the electronic device, the two connectors and the floor 6 are preferably located on the same side of the main board 10 and arranged in a horizontal manner.

In one embodiment of the present disclosure, the electronic device further comprises a radio frequency integrated circuit 3 and an integrated power management circuit 4. The radio frequency integrated circuit 3, the integrated power management circuit 4 and the floor 6 are horizontally arranged and are respectively arranged on the same side of the main board 10.

As can be seen from fig. 1 to fig. 4 in combination with the above description, in the conventional electronic device, a plurality of dual-frequency dual-polarized antenna modules, a radio frequency integrated circuit 3 and an integrated power management circuit 4 are packaged in one module by using a packaged antenna technology, and then the packaged module is installed in the electronic device, so that the radio frequency integrated circuit 3, the integrated power management circuit 4 and a floor 6 are disposed on two sides of a main board 10, and are arranged in a vertical manner, which results in a thicker thickness of the electronic device. For example, the thickness of the whole machine is increased by about 1mm, so that the light and thin appearance effect of the electronic equipment is influenced, and the use experience of a user is reduced.

Unlike this arrangement, as shown in fig. 26, in order to avoid increasing the thickness of the electronic device, the present embodiment arranges the rf ic 3, the integrated power management circuit 4 (not shown in fig. 26), and the floor 6 on the same side of the main board 10 and in a horizontal manner.

Preferably, the radio frequency integrated circuit 3 is preferably arranged adjacent to the second connector to reduce path loss.

In one embodiment of the present disclosure, as shown in fig. 26, the electronic device is a smartphone.
