[0069] Please refer to Figure 1 , which shows a schematic diagram of an antenna module provided by an embodiment of the present application, as shown in Figure 1 , the antenna module includes an antenna substrate 101 (in some documents, the antenna substrate can also be referred to as an antenna film, etc.), a feeding chip 102, a plurality of radiation parts 103, and a plurality of double-to-single converters 104 corresponding to the plurality of radiation parts 103, it should be pointed out that, Figure 1 The number, setting position, setting direction, etc. of the radiation part 103 shown are exemplary, and are only used to reflect that a plurality of radiation parts 103 are arranged on the antenna substrate 101.
[0070] Among them, the plurality of radiation parts 103 are arranged on the antenna substrate 101, and each radiation part 103 is made of a metal grid (not shown in the figure). Figure 1 The feeding chip 102 is connected with each double-to-single converter 104, each double-to-single converter 104 is connected with the corresponding radiation part 103, and the differential signal output by the feeding chip 102 is converted into a single-ended signal by each double-to-single converter 104 and then fed into the corresponding radiation part 103.
[0071] The antenna substrate 101 in the embodiments of the present application can be a hard plate made of a hard material, for example, the hard material can be COP (English: Cyclo Olefin Polymer; Chinese: Cyclo Olefin Polymer), PET (English: Polyethylene terephthalate; Chinese: Polyethylene terephthalate) and the like. In order to enable the antenna module provided by the embodiments of the present application to be applied to the on-screen antenna scenario of the electronic device, the antenna substrate 101 in the antenna module can be a transparent substrate to ensure the normal display of the display screen of the electronic device.
[0072] The feed chip 102 can realize signal amplification, noise suppression, frequency conversion and the like, the feed chip 102 is connected with a processor (for example, CPU, Modem and the like) of the electronic device, and the feed chip 102 is used to receive an intermediate frequency signal (IF signal) sent by the processor and output a differential signal based on the intermediate frequency signal.
[0073] The differential-to-single-ended adapter 104 is a device capable of converting a differential signal into a single-ended signal, for example, the differential-to-single-ended adapter 104 can be a balun adapter or the like. Optionally, in the embodiments of the present application, the input end of the differential-to-single-ended adapter 104 can be impedance matched to 100 ohm, and the differential-to-single-ended adapter 104 can be used to match the impedance to 50 ohm.
[0074] Please refer to Figure 2 , which is a schematic diagram of the radiation part 103 made of a metal grid, wherein, Figure 2 The block 201 in Figure 2 is an equivalent radiation part of the metal grid, and the feed line connected with the block 201 is an equivalent feed line, which does not actually exist on the antenna substrate 101, and is only used for example to facilitate the reader to understand the radiation part 103 provided by the embodiments of the present application. In the optional embodiments of the present application, the radiation part 103 is a dipole radiation part.
[0075] It should be pointed out that the metal grid of the radiation part 103 in the embodiments of the present application can be a diamond grid or a rectangular grid, which is not limited in the embodiments of the present application. In addition, the line width and the line spacing of the metal lines in the metal grid of the radiation part 103 are in the order of microns, and since the line width is small, the metal grid as a whole exhibits a transparent property, which does not affect the normal light transmission and the normal display of the display screen. In actual application, the resonant frequency point of the radiation part is controlled by adjusting the angle, line width and line spacing of the metal lines in the metal grid.
[0076] In addition, it should be pointed out that although it is not mentioned in the above, the reader should understand that in the embodiments of the present application, a feed line is provided between the feed chip 102, the differential-to-single-ended adapter 104 and the radiation part 103, and the signal can be transmitted through the feed line.
[0077] In the antenna module provided by the embodiment of the present application, one signal output port only needs to be connected with the radiation part of one antenna, and the mode of directly feeding the differential signal into the radiation part needs to make one signal output port connected with the radiation parts of two antennas. Compared with the mode of directly feeding the differential signal into the radiation part, the antenna module provided by the present application can significantly reduce the distance between the two adjacent radiation parts, and thus the overall area of the radiation part arranged in the antenna substrate can be reduced, which is beneficial to the light transmittance and touch function of the display screen.
[0078] Please refer to Figure 3 , which is a side view of the antenna substrate 101, as Figure 3 indicated, in the optional embodiment of the present application, one side of the antenna substrate 101 is provided with a radiation part 103, and the other side of the antenna substrate 101 is provided with a ground plate 105 in the region opposite to the radiation part 103. Since the radiation part 103 is not directly connected with the ground plate, the design complexity during modal conversion can be reduced, and the design method can be more intuitive and robust.
[0079] As shown in Figure 1 and Figure 3 , there are regions provided with the radiation part 103 and regions not provided with the radiation part 103 (for the convenience of description, hereinafter referred to as the antenna outer region) on the antenna substrate 101.
[0080] Please refer to Figure 4 , in one optional implementation, the antenna outer region WQ (the region provided with the antenna is indicated as TQ in the figure) can be provided with a metal grid, and the sparsity of the metal grid in the antenna outer region WQ is greater than the sparsity of the metal grid in the radiation part 103. Wherein, in the case of providing the metal grid in the antenna outer region WQ, the ratio of the grid spacing of the metal grid in the antenna outer region WQ to the grid spacing of the metal grid in the radiation part 103 can be a positive integer greater than 1, and the purpose of such design is to reduce the probability of moire appearing.
[0081] Please refer to Figure 5 , in another optional implementation, the antenna outer region WQ (the region provided with the antenna is indicated as TQ in the figure) can not be provided with a metal grid.
[0082] It should be pointed out that, Figure 4 and Figure 5 , the proportional relationship between the antenna outer region WQ and the region TQ provided with the antenna is exemplary.
[0083] In the optional embodiment of the present application, the antenna module further includes a flexible soft plate 106, please refer to Figure 6Optionally, the power supply chip 102 and the dual-ended to single-ended adapter 104 are both mounted on the flexible printed circuit board 106. Figure 6 (Not shown in the image), the radiating portion 103 is disposed in the region of the antenna substrate 101 near the flexible plate 106. Figure 6 (not shown in the image), such as Figure 6 As shown, the antenna substrate 101 and the flexible board 106 are stacked together, and an anisotropic conductive film 107 (ACF) is disposed between the overlapping areas of the antenna substrate 101 and the flexible board 106. In other words, the flexible board 106 and the antenna substrate 101 are connected by the anisotropic conductive film 107 disposed in the middle to achieve signal conduction.
[0084] It should be pointed out that, Figure 6 In this paper, the relative thickness relationship of the flexible PCB 106, the antenna substrate 101, and the anisotropic conductive film 107, as well as the size of their overlapping areas, are merely exemplary.
[0085] In optional embodiments of this application, the flexible printed circuit board 106 can be fabricated using processes such as FPC (Flexible Printed Circuit), LCP (Liquid Crystal Polymer), or fluorine.
[0086] In an optional embodiment of this application, the plurality of radiating portions 103 disposed on the antenna substrate 101 may include a communication radiating portion 1031 for transmitting and receiving millimeter-wave communication signals and a sensing radiating portion 1032 for transmitting and receiving millimeter-wave sensing signals. The sensing radiating portion 1032 may operate at a 60 GHz frequency and can be used to implement sensing functions such as recognizing user gestures and detecting whether a user is approaching. For example, after recognizing a user's gesture, it can enable non-contact control of electronic devices, such as adjusting volume or swiping the screen. After recognizing a user's approach, it can reduce the transmission power, thereby reducing radiation to the human body.
[0087] Please refer to Figure 7 It shows a communication radiating section 1031 and a sensing radiating section 1032 disposed on an antenna substrate 101, such as Figure 7 As shown, the orientation of one part of the radiating part in the communication radiating part 1031 is perpendicular to the orientation of another part of the radiating part in the communication radiating part 1031, thus ensuring the dual polarization of the communication radiating part 1031.
[0088] In optional embodiments of this application, such as Figure 7As shown, the sensing radiation part 1032 can be arranged on the antenna substrate 101 at the same side as a part of the communication radiation part 1031.
[0089] It should be noted that, Figure 7 In the above embodiments, the number, the specific arrangement position, the specific shape, etc. of the communication radiation part 1031 and the sensing radiation part 1032 are exemplary and are not used to limit the present application.
[0090] In optional embodiments of the present application, the communication radiation part 1031 includes a plurality of first radiation parts x1 and a plurality of second radiation parts y1, wherein the first radiation part x1 and the second radiation part y1 correspond to different antenna operating frequency bands, for example, in an optional embodiment of the present application, the first radiation part x1 can operate at a frequency point of 28 GHz, and the second radiation part y1 can operate at a frequency point of 39 GHz.
[0091] In optional embodiments of the present application, the plurality of first radiation parts x1 and the plurality of second radiation parts y1 are arranged staggeredly on the antenna substrate 101, or the plurality of first radiation parts x1 and the plurality of second radiation parts y1 can be arranged non-staggeredly on the antenna substrate.
[0092] It should be noted that, Figure 8 and Figure 9 In the above embodiments, the number, the specific arrangement position, the specific shape, etc. of the first radiation part x1 and the second radiation part y1 are exemplary and are not used to limit the present application. Figure 8 is a schematic view of the plurality of first radiation parts x1 and the plurality of second radiation parts y1 arranged staggeredly on the antenna substrate 101, Figure 9 is a schematic view of the plurality of first radiation parts x1 and the plurality of second radiation parts y1 arranged non-staggeredly on the antenna substrate 101.
[0093] It should be noted that, Figure 8 and Figure 9 In the above embodiments, the sensing radiation part 1032 is not drawn for the sake of simplicity of illustration, and the reader should understand that, Figure 8 and Figure 9 In the above embodiments, the sensing radiation part 1032 is also included, and the arrangement position of the sensing radiation part 1032 is the same as that shown in Figure 7 As shown, 1 / In addition, the reader should understand that, Figure 8 and Figure 9 In the above embodiments, the number, the specific arrangement position, the specific shape, etc. of the first radiation part x1 and the second radiation part y1 are exemplary and are not used to limit the present application.
[0094] It should be noted that, in the optional embodiment of the present application, the distance between any two adjacent first radiation parts x1 is equal to 1 / 2 of the first wavelength, and the distance between any two adjacent second radiation parts y1 is equal to 1 / 2 of the second wavelength, wherein the first wavelength is the wavelength corresponding to the antenna operating frequency band corresponding to the first radiation part x1, for example, the first wavelength is the wavelength corresponding to the frequency point of the antenna operating frequency band corresponding to the first radiation part x1, and the second wavelength is the wavelength corresponding to the antenna operating frequency band corresponding to the second radiation part x2, for example, the second wavelength is the wavelength corresponding to the frequency point of the antenna operating frequency band corresponding to the second radiation part y1. In this way, grating lobes can be avoided within the field of view.
[0095] Since the antenna operating frequency bands corresponding to the first radiation part x1 and the second radiation part y1 are different, the distances between adjacent first radiation parts x1 and the distances between adjacent second radiation parts y1 are different. On this basis, the staggered arrangement of the first radiation part x1 and the second radiation part y1 can make full use of the gap between the first radiation part x1 and the second radiation part y1, so that the overall layout area of the first radiation part x1 and the second radiation part y1 on the antenna substrate 101 is small.
[0096] In the optional embodiment of the present application, if a plurality of first radiation parts x1 and a plurality of second radiation parts y2 are staggered on the antenna substrate 101, the distance between the first radiation part x1 and the edge of the antenna substrate 101 is greater than the distance between the second radiation part y1 and the edge of the antenna substrate 101, wherein the antenna operating frequency band corresponding to the first radiation part x1 is lower than the antenna operating frequency band corresponding to the second radiation part y1. For example, as described above, the first radiation part x1 can operate at a frequency of 28 GHz, and the second radiation part y1 can operate at a frequency of 39 GHz.
[0097] In other words, in the case of staggered arrangement of the first radiation part x1 and the second radiation part y2, the radiation part operating at a higher frequency band is closer to the edge of the antenna substrate 101, and the radiation part operating at a lower frequency band is farther away from the edge of the antenna substrate 101.
[0098] In the optional embodiment of the present application, the above-mentioned sensing radiation part 1032 can be inclinedly arranged on the antenna substrate 101, or the above-mentioned sensing radiation part 1032 can be horizontally arranged on the antenna substrate 101. Optionally, in the case that the sensing radiation part 1032 is inclinedly arranged on the antenna substrate 101, the inclination angle between the sensing radiation part 1032 and the antenna substrate 101 can be 45°.
[0099] Please refer to Figure 10 and Figure 11 , wherein, Figure 10 is a schematic view of the sensing radiation part 1032 being inclinedly arranged on the antenna substrate 101, Figure 11A schematic view of the sensing radiation part 1032 horizontally arranged on the antenna substrate 101.
[0100] In optional embodiments of the present application, a plurality of sensing radiation parts 1032 can be arranged on the antenna substrate 101, wherein the distance between any two adjacent sensing radiation parts 1032 in the plurality of sensing radiation parts 1032 is equal to 1 / 2 of a third wavelength, the third wavelength being a wavelength corresponding to the antenna operating frequency band corresponding to the sensing radiation part 1032. For example, the third wavelength is a wavelength corresponding to a frequency point of the antenna operating frequency band corresponding to the sensing radiation part 1032. Such design can avoid grating lobes within the field of view.
[0101] It should be noted that, Figure 10 and Figure 11 In the above-mentioned embodiments, the number and shape of the sensing radiation part 1032 are exemplary and are not intended to limit the present application.
[0102] In optional embodiments of the present application, the plurality of sensing radiation parts 1032 includes p sensing signal receiving radiation parts x2 and q sensing signal transmitting radiation parts y2, wherein the ratio of p to q is n, n being a positive integer greater than or equal to 1. The sensing signal transmitting radiation part y2 is used to transmit millimeter wave sensing signals to the free space, and the sensing signal receiving radiation part x2 is used to receive millimeter wave sensing signals reflected by external obstacles (e.g., hands, users, etc.). In embodiments of the present application, the sensing signal transmitting radiation part y2 and the sensing signal receiving radiation part x2 can be arranged in a one-to-one or one-to-many (e.g., one-to-two, one-to-three, etc.) ratio.
[0103] Please refer to Figure 12 which is a schematic view of the sensing signal transmitting radiation part y2 and the sensing signal receiving radiation part x2 arranged in a one-to-three ratio. It should be noted that, Figure 12 In the above-mentioned embodiments, the sensing signal transmitting radiation part y2 and the sensing signal receiving radiation part x2 are arranged obliquely on the antenna substrate 101, but the reader should understand that it is also possible that the sensing signal transmitting radiation part y2 and the sensing signal receiving radiation part x2 are arranged horizontally on the antenna substrate 101. Embodiments of the present application are not separately illustrated for brevity of presentation.
[0104] It should be noted that, Figure 12 In the above-mentioned embodiments, the number and shape of the sensing radiation part 1032 are exemplary and are not intended to limit the present application.
[0105] In an optional embodiment of the present application, the p sensing signal receiving radiation parts x2 include a first sensing signal receiving radiation part x21 and a second sensing signal receiving radiation part x22, wherein the distance between the first sensing signal receiving radiation part x21 and the edge of the antenna substrate 101 is greater than the distance between the second sensing signal receiving radiation part x22 and the edge of the antenna substrate 101.
[0106] In other words, in the optional embodiment of the present application, part of the sensing signal receiving radiation parts x2 can be extended inwardly on the antenna substrate 101, and through such a design, the function of three-dimensional identification can be realized.
[0107] Optionally, the distance between the first sensing signal receiving radiation part x21 and the edge of the antenna substrate 101 and the distance between the second sensing signal receiving radiation part x22 and the edge of the antenna substrate 101 differ by 1 / 2 of the third wavelength.
[0108] The present application also provides a display screen, wherein the display screen comprises the antenna module as described in any of the above.
[0109] Please refer to Figure 13 , which is a schematic view of the display screen provided by the present application, as Figure 13 shown, optionally, the display screen provided by the present application further comprises a display screen body P and a glass cover CG, the display screen body P comprises a touch screen assembly TP and a polarizer POL arranged in layers, the antenna module A is arranged on the display screen body P in layers, and the glass cover CG is arranged on the antenna module A in layers.
[0110] Among them, the glass cover CG and the antenna module A are bonded by a colloid, and the antenna module A and the display screen body P are also bonded by a colloid, and optionally, the colloid can be OCA (English full name: Optically Clear Adhesive) optical glue.
[0111] Optionally, in order to improve the visual visibility, the radiation part in the antenna module A is arranged on the side of the antenna substrate close to the glass cover CG, and in addition, a surface blackening process can also be used.
[0112] In addition, as Figure 13As shown, the display screen can be divided into a black border area and an active area (AA).

In addition, the double-to-single converter, the feeding chip, and the feed line included in the antenna module A can be arranged in the black border area. Since the double-to-single converter, the feeding chip, and the feed line are designed in the black border area, they will not be found by the user. Such a setting mode can not only ensure the radiation performance of the antenna module A, but also ensure the display performance of the display screen, avoiding affecting the normal display of the display screen.
[0113] As shown in Figure 13 , the flexible soft plate RB in the antenna module A is folded under the display screen body P, as shown in Figure 13 , the flexible soft plate RB in the antenna module A is connected with the antenna substrate JB through ACF.
[0114] In optional embodiments of the present application, the thickness of the glass cover CG of the display screen provided by the embodiments of the present application is in the order of ten microns. Since the thickness of CG is only a few tens of microns, it is much smaller than the highest frequency point wavelength. Compared with the conventional CG design of hundreds of microns, the multiple reflection signals of the discontinuous surface can be greatly reduced, and the radiation performance of the antenna module is also improved.
[0115] Please refer to Figure 14 , which shows the antenna simulation schematic diagram of the communication radiation part in the antenna module under the conditions of thick (hundreds of microns) and thin (tens of microns) glass cover CG, respectively located on the left and right sides of Figure 14 , and please refer to Figure 15 , which shows the antenna simulation schematic diagram of the sensing radiation part in the antenna module under the conditions of thick (hundreds of microns) and thin (tens of microns) glass cover CG, respectively located on the left and right sides of Figure 15 .
[0116] As shown in Figure 14 and Figure 15 , under the condition of thin glass cover CG, the corresponding radiation field pattern of the antenna module is more full and concentrated, and the antenna gain is better.
[0117] In optional embodiments of the present application, a floor is arranged between the glass cover CG of the display screen and the flexible soft plate RB of the antenna module A. In addition, as described above, the floor is arranged in the area on one side of the antenna substrate JB of the antenna module A. The two floors can form a closed structure, which can isolate the interference signals from the display screen body P.
