[0002] With the development of communication technology, electronic devices equipped with antenna modules and antenna arrays to achieve communication functions are being used more and more widely. However, in related technologies, the performance of antenna modules and antenna arrays installed in electronic devices is relatively poor when communicating with polarized wireless devices. Therefore, how to improve the communication performance of these antenna modules and antenna arrays has become a technical problem that needs to be solved. Summary of the Invention

[0003] This application provides an antenna module, antenna array, and electronic device with a simple feeding structure that can improve radiation performance through phase shift.

[0004] On the one hand, this application provides an antenna module, including:

[0006] A power supply unit includes a first power supply element and a second power supply element spaced apart. The first power supply element includes a transmission section, a first power supply section, and a second power supply section connected in sequence. The transmission section is used to electrically connect to a radio frequency (RF) signal source. The first power supply section is disposed opposite to and coupled to one of the first radiating arms. The second power supply section is disposed opposite to and coupled to another of the first radiating arms. The third power supply section includes a third power supply section, a first connecting section, and a fourth power supply section connected in sequence. One end of the third power supply section is electrically connected to one of the second radiating arms, and the other end is used to electrically connect to the RF signal source. One end of the fourth power supply section is electrically connected to another of the second radiating arms. The first connecting section is used to transmit the RF current between the third power supply section and the fourth power supply section and to adjust the phase difference between the RF current of the third power supply section and the RF current of the fourth power supply section.

[0009] The antenna module provided in this application includes a pair of first radiating arms, a pair of second radiating arms, a first feed element, and a second feed element. Since the first feed element is electrically connected to a radio frequency (RF) signal source and coupled to the pair of first radiating arms, the third feed part of the second feed element is electrically connected to the RF signal source and electrically connected to one second radiating arm, and the fourth feed part of the second feed element is electrically connected to the other second radiating arm, and the first connecting part of the second feed element is electrically connected between the third and fourth feed parts, the first and second feed elements respectively form a feeding system for a pair of first radiating arms and a pair of second radiating arms. This system can be used to feed both pairs of first and second radiating arms. The feeding system formed by the first and second feed elements has a simple structure and is easy to manufacture. Furthermore, the first connecting part is used to adjust the phase difference between the RF currents of the third and fourth feed parts, which can control the phase difference between the RF currents of the pair of second radiating arms, enabling adjustment of the radiation direction and linear polarization of the pair of second radiating arms, thereby improving their communication performance when communicating with wireless devices.

All other embodiments obtained by those skilled in the art based on the embodiments provided in this application without creative effort are within the protection scope of this application.

[0051] In this application, the reference to "embodiment" or "implementation" means that a specific feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of this application.

[0052] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0053] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of an electronic device 100 provided in an embodiment of this application. The electronic device 100 can be a mobile phone, tablet computer, laptop computer, computer, watch, drone, robot, base station, radar, customer premise equipment (CPE), vehicle-mounted equipment, home appliance, or other device with wireless communication capabilities. This embodiment uses a mobile phone as an example.

[0054] Please refer to Figures 1 to 3 The electronic device 100 includes a device body 3 and an antenna module 1 or an antenna array 2. The device body 3 carries the antenna module 1 or the antenna array 2. The frequency bands supported by the antenna array 2 and the antenna module 1 include, but are not limited to, the 5G millimeter-wave band.

[0055] In one embodiment, please refer to Figure 1 and Figure 2 The electronic device 100 includes a device body 3 and an antenna module 1. The antenna module 1 is used to transmit and receive electromagnetic wave signals (which can be 5G millimeter-wave signals or electromagnetic wave signals in other frequency bands) to realize the communication function of the electronic device 100. This application does not specifically limit the location of the antenna module 1 within the electronic device 100. Figure 2This is merely an example and should not be construed as limiting the location of the antenna module 1 within the electronic device 100. The device body 3 is used to support the antenna module 1. Specifically, the device body 3 includes, but is not limited to, components such as a display screen 31, a housing 32 (middle frame 320 and back cover 321), a circuit board 33, and a camera module 34. The display screen 31 is interconnected with the housing 32, and the circuit board 33 is located within the space between the display screen 31 and the housing 32. The antenna module 1 can be directly supported on one or more components of the device body 3 (e.g., the circuit board 33 or the housing 32), or it can be supported on one or more components of the device body 3 through other supporting structures. The antenna module 1 can be located within the device body 3 (i.e., within the space between the display screen 31 and the housing 32), or it can be partially integrated into the housing 32 of the device body 3.

[0056] In another embodiment, please refer to Figure 1 and Figure 3 The electronic device 100 includes a device body 3 and an antenna array 2. The antenna array 2 is used to transmit and receive electromagnetic wave signals (which can be 5G millimeter-wave signals or electromagnetic wave signals in other frequency bands) to realize the communication function of the electronic device 100. This application does not specify the location of the antenna array 2 on the electronic device 100. Figure 3 This is merely an example and should not be construed as limiting the location of the antenna array 2 within the electronic device 100. The device body 3 is used to support the antenna array 2. Specifically, the device body 3 includes, but is not limited to, components such as a display screen 31, a housing 32 (middle frame 320 and rear cover 321), and a circuit board 33. The display screen 31 is interconnected with the housing 32, and the circuit board 33 is located in the space between the display screen 31 and the housing 32. The antenna array 2 can be directly supported on one or more components of the device body 3, or it can be supported on one or more components of the device body 3 through other supporting structures. The antenna array 2 can be located within the device body 3 (i.e., within the space between the display screen 31 and the housing 32), or it can be partially integrated into the housing 32 of the device body 3.

[0057] As electronic devices 100 become thinner and smaller, the space available for antenna modules 1 and antenna arrays 2 inside electronic devices 100 becomes increasingly limited. Therefore, miniaturizing and compacting antenna modules 1 and antenna arrays 2 is beneficial for better application of antenna modules 1 and antenna arrays 2 in electronic devices 100 with limited space, thereby enabling the communication functions of electronic devices 100.

[0058] Furthermore, millimeter-wave communication, with its abundant spectrum, has become crucial for 5G applications. In the millimeter-wave communication era, antennas with broadband performance are a key research focus. The 5G millimeter-wave frequency band covers 24.75GHz–27.5GHz and 37GHz–43.5GHz. As the operating frequency increases, the antenna size decreases. However, to achieve tightly coupled antenna design in the 5G millimeter-wave band and avoid pattern grating lobes during wide-angle scanning, it is necessary to further reduce the antenna volume and profile.

[0059] To this end, this application provides a small-sized, low-profile, and wide-bandwidth dual-polarized dipole antenna module 1 and a small-sized, low-profile, and wide-bandwidth tightly coupled dual-polarized dipole antenna array 2. The following embodiments provide a detailed description of the antenna module 1 and antenna array 2 provided in this application.

[0060] like Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of an antenna module 1 provided in an embodiment of this application. The antenna module 1 includes a radiating element 10 and a feeding element 20.

[0061] Please refer to Figure 4 and Figure 5 The radiation unit 10 includes a pair of first radiation arms 101 arranged along a first direction and a pair of second radiation arms 102 arranged along a second direction. Specifically, the pair of first radiation arms 101 are arranged opposite to each other and spaced apart along the first direction. The pair of second radiation arms 102 are arranged opposite to each other and spaced apart along the second direction. The pair of first radiation arms 101 forms a dipole. The pair of second radiation arms 102 forms a dipole. The first direction and the second direction intersect. The intersection of the first direction and the second direction includes two intersecting directions within the same plane, or two staggered directions in space. In other words, the pair of first radiation arms 101 and the pair of second radiation arms 102 can be arranged coplanarly or non-coplanarly. In the following embodiments, unless otherwise specified, the pair of first radiation arms 101 and the pair of second radiation arms 102 are arranged non-coplanarly as an example. The pair of first radiating arms 101 and the pair of second radiating arms 102 are arranged in opposite directions, which facilitates a compact arrangement of the first radiating arms 101 and the pair of second radiating arms 102, thereby reducing the size of the antenna module 1 along the first and second directions. It also reduces the coupling between the pair of first radiating arms 101 and the pair of second radiating arms 102, i.e., reduces the internal coupling effect of the antenna module 1. The angle between the first and second directions can be 30°, 35°, 55°, 60°, 70°, 85°, 90°, etc. In this embodiment, the first direction is perpendicular to the second direction as an example. The first direction can be referred to in the appendix. Figure 4 The X-axis direction; the second direction can be referred to in the appendix. Figure 4The Y-axis direction. Of course, in other embodiments, the first direction and the second direction may intersect but not be perpendicular. The materials of the first radiating arm 101 and the second radiating arm 102 are both conductive. For example, the materials of the first radiating arm 101 and the second radiating arm 102 can be metal, alloy, etc. This application does not specifically limit the shape of the first radiating arm 101 and the shape of the second radiating arm 102. Figure 5 The shapes of the first radiating arm 101 and the second radiating arm 102 are merely examples. The shapes of the first radiating arm 101 and the second radiating arm 102 may be the same or different.

[0062] The feeding unit 20 and the radiating unit 10 are arranged opposite to each other. Specifically, the feeding unit 20 and the radiating unit 10 are arranged opposite to each other along the thickness direction of the antenna module 1. The thickness direction of the antenna module 1 can be referred to in the appendix. Figure 4 The Z-axis direction. The power supply unit 20 includes a first power supply component 201 and a second power supply component arranged at intervals. The second power supply component includes a third power supply section 202, a first connecting section 30 and a fourth power supply section 203 connected in sequence.

[0063] The first feed element 201 is made of a conductive material. For example, the material of the first feed element 201 can be metal, alloy, etc. The first feed element 201 includes a transmission section 210, a first feed section 211, and a second feed section 212 connected in sequence. It should be noted that the sequential connection of the transmission section 210, the first feed section 211, and the second feed section 212 can be an integral connection, or it can be a direct connection (e.g., welding) between them. It is understood that the sequential connection of the transmission section 210, the first feed section 211, and the second feed section 212 indicates that the radio frequency current of the transmission section 210, the radio frequency current of the first feed section 211, and the radio frequency current of the second feed section 212 can be transmitted to each other. The transmission section 210 is used to electrically connect to the radio frequency signal source. The first feed section 211 is disposed opposite to and coupled to a first radiating arm 101. The second feed section 212 is disposed opposite to and coupled to another first radiating arm 101. The transmission section 210 can be directly electrically connected to the radio frequency signal source, or it can be electrically connected to the radio frequency signal source through conductive traces, conductive components, etc. The first feed section 211 and one first radiating arm 101 are disposed opposite to each other along the thickness direction of the antenna module 1, forming a first coupling gap. The second feed section 212 and another first radiating arm 101 are disposed opposite to each other along the thickness direction of the antenna module 1, forming a second coupling gap. The first coupling gap and the second coupling gap can be the same or different. In other words, the distance between the first feed section 211 and one first radiating arm 101 along the thickness direction of the antenna module 1, and the distance between the second feed section 212 and another first radiating arm 101 along the thickness direction of the antenna module 1, can be the same or different. In the following embodiments, unless otherwise specified, the first coupling gap and the second coupling gap are the same as an example. This application does not specifically limit the shape of the first feed member 201. For example, the transmission section 210 of the first power supply component 201 can be a power supply probe, a power supply post, etc., the first power supply section 211 of the first power supply component 201 can be a power supply spring, a strip wire, etc., and the second power supply section 212 of the first power supply component 201 can be a power supply spring, a strip wire, etc. In this embodiment, the first power supply section 211 and the second power supply section 212 are both circular power supply pieces. Of course, in other embodiments, the shape of the first power supply section 211 and the shape of the second power supply section 212 can also be elliptical, square, rectangular, triangular, other polygonal, E-shaped, L-shaped, and various irregular shapes, etc.

[0064] In one application scenario, when the antenna module 1 is used to transmit wireless signals, the radio frequency signal source generates radio frequency current (high-frequency current) and transmits it to the transmission section 210 of the first feed unit 201. The transmission section 210 of the first feed unit 201 transmits the received radio frequency current to the first feed section 211 and the second feed section 212 of the first feed unit 201, respectively. The first feed section 211 of the first feed unit 201 transmits the radio frequency current to a first radiating arm 101 through coupling with the first radiating arm 101. The first radiating arm 101 converts the received radio frequency current into a wireless signal and radiates it towards the outside of the antenna module 1. The second feed section 212 of the first feed unit 201 transmits the radio frequency current to another first radiating arm 101 through coupling with the other first radiating arm 101. The first radiating arm 101 converts the received radio frequency current into a wireless signal and radiates it towards the outside of the antenna module 1. In another application scenario, when the antenna module 1 is used to receive wireless signals, a pair of first radiating arms 101 receive wireless signals in the space and convert them into radio frequency currents, which are then transmitted to the first feed section 211 and the second feed section 212 of the first feed member 201, respectively. The first feed section 211 and the second feed section 212 of the first feed member 201 transmit the received radio frequency currents to the radio frequency signal source via the transmission section 210.

[0065] The third feed section 202 is made of a conductive material. For example, the material of the third feed section 202 can be metal, alloy, etc. One end of the third feed section 202 is electrically connected to a second radiating arm 102, and the other end of the third feed section 202 is used to electrically connect to an RF signal source. The third feed section 202 is used to transmit the RF current between the second radiating arm 102 and the RF signal source. One end of the third feed section 202 can be directly electrically connected to the second radiating arm 102. The other end of the third feed section 202 can be directly electrically connected to the RF signal source, or it can be electrically connected to the RF signal source through conductive traces, conductive components, etc. This application does not specifically limit the shape of the third feed section 202. For example, the third feed section 202 can be a feed probe, a feed spring, a feed post, etc.

[0066] In one application scenario, when antenna module 1 is used to transmit wireless signals, the radio frequency (RF) signal source generates RF current (high-frequency current) and transmits it to the third feed unit 202. The third feed unit 202 then transmits the received RF current to a second radiating arm 102, which converts it into a wireless signal and radiates it towards the outside of antenna module 1. In another application scenario, when antenna module 1 is used to receive wireless signals, the second radiating arm 102 receives the wireless signals in space and converts them into RF current, which is then transmitted to the third feed unit 202. The third feed unit 202 then transmits the received RF current to the RF signal source.

[0067] The fourth feed section 203 is made of a conductive material. For example, the material of the fourth feed section 203 can be metal, alloy, etc. One end of the fourth feed section 203 is electrically connected to another second radiating arm 102, and the other end of the fourth feed section 203 is electrically connected to the third feed section 202 through the first connecting part 30. The fourth feed section 203 is used to transmit the radio frequency current between the second radiating arm 102 and the third feed section 202. One end of the fourth feed section 203 can be directly electrically connected to the second radiating arm 102. This application does not specifically limit the shape of the fourth feed section 203. For example, the fourth feed section 203 can be a feed probe, a feed spring, a feed post, etc.

[0068] In one application scenario, when antenna module 1 is used to transmit wireless signals, the radio frequency (RF) signal source generates RF current (high-frequency current) and transmits it to the third feed unit 202. The RF current of the third feed unit 202 is transmitted to the fourth feed unit 203 through the first connection unit 30. The fourth feed unit 203 transmits the received RF current to another second radiating arm 102, and through the second radiating arm 102, it is converted into a wireless signal and radiated towards the outside of antenna module 1. In another application scenario, when antenna module 1 is used to receive wireless signals, the other second radiating arm 102 receives the wireless signal in the space and converts it into RF current, which is transmitted to the fourth feed unit 203. The fourth feed unit 203 transmits the received RF current to the first connection unit 30, and through the first connection unit 30 and the third feed unit 202, it is transmitted to the RF signal source.

[0069] The first connecting portion 30 is electrically connected between the other ends of the third feed portion 202 and the fourth feed portion 203, and is used to transmit the radio frequency current between the third feed portion 202 and the fourth feed portion 203 and to adjust the phase difference between the radio frequency currents of the third feed portion 202 and the fourth feed portion 203. It is understood that in this application, one of the pair of second radiating arms 102 directly obtains the radio frequency current through the third feed portion 202, while the other second radiating arm 102 obtains the radio frequency current through the fourth feed portion 203, the first connecting portion 30, and the third feed portion 202. The first connecting portion 30 can be bent, curved, or extended in a straight line between the third feed portion 202 and the fourth feed portion 203. This application does not specifically limit the shape, size, etc., of the first connecting portion 30. Figure 5This is merely an example of a first connection portion 30 and should not be construed as limiting the structure of the first connection portion 30. In one embodiment, the first connection portion 30 may be symmetrical along the line connecting the third feed portion 202 and the fourth feed portion 203. The first connection portion 30 may include conductive wires, conductive posts, conductive sheets, etc. The material of the first connection portion 30 may be metal, alloy, etc. The first connection portion 30 is used to cause a phase delay between the RF current of the fourth feed portion 203 (which is not directly electrically connected to the RF signal source) and the RF current of the third feed portion 202 (which is directly electrically connected to the RF signal source), thereby causing a phase delay between the RF currents of a pair of second radiating arms 102, so that the phase difference between the RF currents of a pair of second radiating arms 102 meets the design requirements. The length of the first connection portion 30 may be designed based on specific phase difference requirements. For example, the length of the first connection portion 30 may be a quarter wavelength, half wavelength, etc., of the operating frequency of the antenna module 1.

[0070] In one possible application scenario, the first connection portion 30 is used to adjust the phase difference between the RF current of the third feed portion 202 and the RF current of the fourth feed portion 203, so that the third feed portion 202 and the fourth feed portion 203 have in-phase or out-of-phase RF currents, that is, the phase difference between the RF current of the third feed portion 202 and the RF current of the fourth feed portion 203 is nπ (where n is greater than or equal to 1 and is an integer), thereby making the phase difference between the RF currents of the pair of second radiating arms 102 nπ. Optionally, the first connection portion 30 is used to adjust the phase difference between the RF current of the third feed portion 202 and the RF current of the fourth feed portion 203, so that the phase difference between the RF current of the third feed portion 202 and the RF current of the fourth feed portion 203 is 180°. Of course, in other application scenarios, the first connection part 30 can be used to adjust the phase difference between the RF current of the third feed part 202 and the RF current of the fourth feed part 203, so that the phase difference between the third feed part 202 and the fourth feed part 203 is 360°. By adjusting the first connection part 30, the third feed part 202 and the fourth feed part 203 have out-of-phase or in-phase RF currents, so that the pair of second radiating arms 102 have out-of-phase or in-phase RF currents, which can realize the linear polarization of the pair of second radiating arms 102, thereby facilitating communication between the antenna module 1 and devices with the same linear polarization, and improving the benefit and efficiency of the antenna module 1.

[0071] Please refer to Figure 5 and Figure 6 , Figure 6The antenna module 1 provided in this application embodiment also includes a structural schematic diagram of a dielectric layer 40. This application does not specifically limit the number of dielectric layers 40. A pair of first radiating arms 101 can be supported on the surface of the dielectric layer 40 or inside the dielectric layer 40, a pair of second radiating arms 102 can be supported on the surface of the dielectric layer 40 or inside the dielectric layer 40, and the first feed element 201, the third feed part 202, and the fourth feed part 203 can penetrate within the dielectric layer 40.

[0072] The antenna module 1 provided in this application includes a pair of first radiating arms 101, a pair of second radiating arms 102, a first feed element 201, a third feed section 202, a fourth feed section 203, and a first connecting part 30. The first feed element 201 is electrically connected to a radio frequency signal source and coupled to the pair of first radiating arms 101. The third feed section 202 is electrically connected to a radio frequency signal source and electrically connected to one of the second radiating arms 102. The fourth feed section 203 is electrically connected to the other second radiating arm 102. The first connecting part 30... The first feed unit 201, the third feed unit 202, the first connecting part 30, and the fourth feed unit 203 are electrically connected between the third feed unit 202 and the fourth feed unit 203. Therefore, the first feed unit 201, the third feed unit 202, the first connecting part 30, and the fourth feed unit 203 form a feed system for a pair of first radiating arms 101 and a pair of second radiating arms 102. This system can be used to feed the pair of first radiating arms 101 and the pair of second radiating arms 102. The feed system formed by the first feed unit 201, the third feed unit 202, the first connecting part 30, and the fourth feed unit 203 has a simple structure and is easy to manufacture. The feed unit (first feed unit 201, third feed unit 202, and fourth feed unit 203) and the radiating unit (a pair of first radiating arms 101 and a pair of second radiating arms 102) are stacked. The first connecting part 30 is electrically connected between the third feed unit 202 and the fourth feed unit 203. This facilitates the arrangement of the first connecting part 30 in the layer where the feed unit 10 is located, reduces the cross-section of the antenna module 1, and reduces the volume of the antenna module 1. In addition, the first connection part 30 is used to adjust the phase difference between the radio frequency currents of the third feed part 202 and the fourth feed part 203, which can control the phase difference between the radio frequency currents of a pair of second radiating arms 102, realize the radiation direction adjustment, linear polarization, etc. of a pair of second radiating arms 102, and thus help improve its communication performance when communicating with devices with the same polarization.

[0073] Please refer to Figure 6 and Figure 7The first connecting portion 30 can be disposed on the same layer as the feeding unit 20. In other words, along the thickness direction of the antenna module 1, the first connecting portion 30 is located between the side of the radiating unit 10 facing the feeding unit 20 and the side of the feeding unit 20 away from the radiating unit 10. It can be understood that the first connecting portion 30 is disposed on the same layer as the first feeding member 201, the third feeding member 202, and the fourth feeding member 203. In one embodiment, the first connecting portion 30 can be carried on the same dielectric layer 40 as the first feeding member 201, the third feeding member 202, and the fourth feeding member 203. By disposing the first connecting portion 30 on the same layer as the feeding unit 20, the cross-section of the antenna module 1 is not increased, which is beneficial for the low profile and miniaturization of the antenna module 1.

[0074] like Figure 8 As shown, the transmission section 210 is bent and connected to the first feed section 211. In other words, the extension direction of the transmission section 210 is different from the extension direction of the first feed section 211. In one possible embodiment, the transmission section 210 extends along the thickness direction (Z-axis direction) of the antenna module 1, and the first feed section 211 is located in the XY plane, that is, the first feed section 211 extends along the X-axis direction or the Y-axis direction. It can be understood that in this embodiment, the transmission section 210 and the first feed section 211 are bent and connected at approximately 90°, that is, the transmission section 210 and the first feed section 211 form an "L"-shaped feed structure. Since the transmission section 210 is used to electrically connect to the radio frequency signal source, and the transmission section 210 is bent and connected to the first feed section 211, the radio frequency current generated by the radio frequency signal source can be transmitted to the first feed section 211 through the transmission section 210, and then coupled to a first radiating arm 101 through the first feed section 211.

[0075] By bending the transmission section 210 and connecting it to the first feed section 211, it is beneficial to arrange the first feed section 211 and a first radiating arm 101 opposite each other and coupled along the thickness direction of the antenna module 1, and to arrange the second feed section 212 and another second radiating arm 102 opposite each other and coupled along the thickness direction of the antenna module 1. This allows the transmission section 210 and the first feed section 211 to also be arranged along the thickness direction of the antenna module 1, forming a vertically arranged antenna module 1, and reducing the size of the antenna module 1, which is conducive to the miniaturization of the antenna module 1.

[0076] like Figure 8As shown, the antenna array 2 also includes a second connecting portion 50. One end of the second connecting portion 50 is electrically connected to the first feed portion 211, and the other end is electrically connected to the second feed portion 212. The second connecting portion 50 is used to transmit the radio frequency current between the first feed portion 211 and the second feed portion 212 and to adjust the phase difference between the radio frequency current of the first feed portion 211 and the radio frequency current of the second feed portion 212. Specifically, one end of the second connecting portion 50 is directly electrically connected to the first feed portion 211, and the other end is directly electrically connected to the second feed portion 212. The second connecting portion 50, the first feed portion 211, and the second feed portion 212 can be arranged coplanarly or non-coplanarly. In one possible embodiment, the first feed portion 211, the second connecting portion 50, and the second feed portion 212 can be integrally formed. This application does not specifically limit the shape, size, etc. of the second connecting portion 50. Figure 8 This is merely an example of a second connection portion 50 and should not be construed as limiting the structure of the second connection portion 50. For example, in other embodiments, the second connection portion 50 may be bent or extended by bending. The material of the second connection portion 50 may be metal, alloy, etc. The second connection portion 50 is used to create a phase delay between the RF current of the second feed portion 212 and the RF current of the first feed portion 211, so that the phase difference of the RF current between the pair of first radiating arms 101 meets design requirements. The length of the second connection portion 50 may be designed based on specific phase difference requirements. For example, the length of the second connection portion 50 may be a quarter wavelength, half wavelength, etc., of the operating frequency of the antenna module 1.

[0077] Understandably, the radio frequency current generated by the radio frequency signal source is transmitted to the first feed unit 211 via the transmission unit 210, and coupled to a first radiating arm 101 via the first feed unit 211. It is also transmitted to the second feed unit 212 via the first feed unit 211 and the second connection unit 50, and coupled to another first radiating arm 101 via the second feed unit 212.

[0078] In one possible application scenario, the second connection portion 50 is used to adjust the phase difference between the radio frequency currents of the first feed portion 211 and the second feed portion 212. Since the first feed portion 211 is coupled to one first radiating arm 101 and the second feed portion 212 is coupled to the other first radiating arm 101, the second connection portion 50 can adjust the radio frequency currents of the first feed portion 211 and the second feed portion 212 to have out-of-phase or in-phase radio frequency currents, thereby enabling the pair of first radiating arms 101 to have out-of-phase or in-phase radio frequency currents, i.e., the phase difference between the radio frequency currents of the pair of first radiating arms 101 is nπ (where n is greater than or equal to 1 and is an integer). By adjusting the second connection portion 50 to enable the pair of first radiating arms 101 to have out-of-phase or in-phase radio frequency currents, linear polarization of the pair of first radiating arms 101 can be achieved, which is beneficial for the antenna module 1 to communicate with devices with the same polarization, thereby improving the benefit and efficiency of the antenna module 1.

[0079] Understandably, in this application, a pair of first radiating arms 101 can form linear polarization, and a pair of second radiating arms 102 can form linear polarization, that is, antenna module 1 can be a cross-polarized dipole antenna module.

[0080] Optionally, the first direction and the second direction are orthogonal, and a pair of first radiating arms 101 and a pair of second radiating arms 102 can form horizontal and vertical dual polarization, or ±45° dual polarization. Horizontal and vertical dual polarization can receive antenna signals in both horizontal and vertical polarization directions, thereby forming an orthogonal dual-polarized dipole antenna module 1 to improve the performance of antenna module 1 when communicating with devices having horizontal and / or vertical polarization. ±45° dual polarization can receive antenna signals in any polarization direction, thereby forming an orthogonal dual-polarized dipole antenna module 1 to improve the performance of antenna module 1 in receiving wireless signals from all directions.

[0081] Please refer to Figure 6 and Figure 8 The second connecting portion 50 is disposed on the same layer as the feeding unit 20. In other words, along the thickness direction of the antenna module 1, the second connecting portion 50 is located between the side of the radiating unit 10 facing the feeding unit 20 and the side of the feeding unit 20 away from the radiating unit 10. It can be understood that the second connecting portion 50 is disposed on the same layer as the first feeding member 201, the third feeding portion 202, and the fourth feeding portion 203. In one embodiment, the second connecting portion 50 may be carried on the same dielectric layer 40 as the first feeding member 201, the third feeding portion 202, and the fourth feeding portion 203. By disposing the second connecting portion 50 on the same layer as the feeding unit 20, the cross-section of the antenna module 1 is not increased, which is beneficial for the low profile and miniaturization of the antenna module 1.

[0082] In one embodiment, such as Figure 9As shown, the first connecting portion 30 includes a first sub-connecting portion 301, a second sub-connecting portion 302, and a third sub-connecting portion 303 connected in sequence. The sequential connection of the first sub-connecting portion 301, the second sub-connecting portion 302, and the third sub-connecting portion 303 can be either integrally connected or directly connected (e.g., soldered) together. It is understood that the sequential connection of the first sub-connecting portion 301, the second sub-connecting portion 302, and the third sub-connecting portion 303 indicates that the radio frequency current of the first sub-connecting portion 301, the second sub-connecting portion 302, and the third sub-connecting portion 303 can be mutually transmitted. The end of the first sub-connecting portion 301 away from the second sub-connecting portion 302 is electrically connected to the third feed portion 202. The end of the third sub-connecting portion 303 away from the second sub-connecting portion 302 is electrically connected to the fourth feed portion 203. Understandably, the RF current of the third feed section 202 can be transmitted sequentially through the first sub-connection section 301, the second sub-connection section 302, and the third sub-connection section 303 to the fourth feed section 203; the RF current of the fourth feed section 203 can be transmitted sequentially through the third sub-connection section 303, the second sub-connection section 302, and the first sub-connection section 301 to the third feed section 202. The first sub-connection section 301, the second sub-connection section 302, and the third sub-connection section 303 can all be transmission lines (e.g., striplines, bar lines, etc.).

[0083] The first sub-connector 301, the second sub-connector 302, and the third sub-connector 303 are coplanar. This coplanarity facilitates the molding of the first sub-connector 301, the second sub-connector 302, and the third sub-connector 303 within the same plane of the dielectric layer 40. It also reduces the manufacturing difficulty of the first connector 30 while adjusting the phase difference of the RF current between the third feed section 202 and the fourth feed section 203 to achieve linear polarization of a pair of second radiating arms 102, thereby improving the mass production and efficiency of the antenna module 1. Furthermore, it allows for a reduction in the overall cross-sectional area of ​​the antenna module 1.

[0084] In this embodiment, at least a portion of the first sub-connection portion 301 can extend along a first direction, the second sub-connection portion 302 can extend along a second direction, and at least a portion of the third sub-connection portion 303 can extend along the first direction. It is understood that the extension direction of at least a portion of the first sub-connection portion 301 is the same as the extension direction of at least a portion of the third sub-connection portion 303, and the extension direction of the second sub-connection portion 302 intersects with the extension directions of at least a portion of the first sub-connection portion 301 and at least a portion of the third sub-connection portion 303. In this embodiment, since the extension directions of the first sub-connection portion 301, the second sub-connection portion 302, and the third sub-connection portion 303 are not entirely the same, a bent first connection portion 30 can be formed. This facilitates the extension dimension of the first connection portion 30 to meet the design requirements of the phase difference between the RF current of the third feed portion 202 and the RF current of the fourth feed portion 203. Simultaneously, the bent first connection portion 30 occupies less space, which also helps to improve the compactness of the antenna module 1.

[0085] In one embodiment, the first sub-connecting portion 301 includes a first sub-connecting segment 3010 and a second sub-connecting segment 3011 that are bent and connected together. Specifically, the end of the first sub-connecting segment 3010 away from the second sub-connecting segment 3011 can be directly electrically connected to the third power supply unit 202, and the end of the second sub-connecting segment 3011 away from the first sub-connecting segment 3010 can be directly electrically connected to one end of the second sub-connecting portion 302. A portion of the first sub-connecting segment 3010 can extend along a first direction, and a portion of the second sub-connecting segment 3011 can extend along a second direction. The bending angle between the first sub-connecting segment 3010 and the second sub-connecting segment 3011 can be less than 90°, equal to 90°, or greater than 90°; or the first sub-connecting segment 3010 and the second sub-connecting segment 3011 can be connected in an arc shape. The third sub-connecting portion 303 includes a third sub-connecting segment 3030 and a fourth sub-connecting segment 3031 that are bent and connected together. Specifically, the end of the third sub-connecting portion 3030 furthest from the fourth sub-connecting portion 3031 can be directly electrically connected to the fourth power supply unit 203, and the end of the fourth sub-connecting portion 3031 furthest from the third sub-connecting portion 3030 can be directly electrically connected to the other end of the second sub-connecting portion 302. A portion of the third sub-connecting portion 3030 can extend along a first direction, and a portion of the fourth sub-connecting portion 3031 can extend along a second direction. The bending angle between the third sub-connecting portion 3030 and the fourth sub-connecting portion 3031 can be less than 90°, equal to 90°, or greater than 90°; alternatively, the third sub-connecting portion 3030 and the fourth sub-connecting portion 3031 can be connected in an arc shape. It is understood that in this embodiment, a portion of the first sub-connecting portion 301 extends along the first direction, and a portion of the third sub-connecting portion 303 extends along the first direction.

[0086] By including a bent-connected first sub-connection portion 3010 and a bent-connected second sub-connection portion 3011 in the first sub-connection portion 301, a bent-shaped first sub-connection portion 301 can be formed. This facilitates further extending the size of the first connection portion 30 to meet the design requirements for the phase difference between the RF current of the third feed portion 202 and the RF current of the fourth feed portion 203. Simultaneously, the bent-shaped first sub-connection portion 301 further reduces the space occupied by the first connection portion 30, further improving the compactness of the antenna module 1. Similarly, by including a bent-connected third sub-connection portion 3030 and a bent-connected fourth sub-connection portion 3031 in the third sub-connection portion 303, a bent-shaped third sub-connection portion 303 can be formed. This facilitates further extending the size of the first connection portion 30 to meet the design requirements for the phase difference between the RF current of the third feed portion 202 and the RF current of the fourth feed portion 203. Simultaneously, the bent-shaped third sub-connection portion 303 further reduces the space occupied by the first connection portion 30, further improving the compactness of the antenna module 1.

[0087] Optionally, the first sub-connecting portion 301 and the third sub-connecting portion 303 are symmetrical. In other words, the first sub-connecting portion 3010 and the third sub-connecting portion 3030 are symmetrical about the centerline of the second sub-connecting portion 302, and the second sub-connecting portion 3011 and the fourth sub-connecting portion 3031 are symmetrical about the centerline of the second sub-connecting portion 302. The centerline of the second sub-connecting portion 302 can be referenced... Figure 9 The M-line in the middle. By making the first sub-connecting part 301 and the third sub-connecting part 303 symmetrical, it is beneficial to form a structurally symmetrical first connecting part 30, thereby facilitating the design of the length of the first connecting part 30 to make the phase difference between the third power supply part 202 and the fourth power supply part 203 nπ.

[0088] Optional, such as Figure 10As shown, the second connecting portion 50, the first feed portion 211, and the second feed portion 212 are coplanar. In this embodiment, the coplanarity of the second connecting portion 50, the first feed portion 211, and the second feed portion 212 facilitates the electrical connection of the second connecting portion 50 between the first feed portion 211 and the second feed portion 212, without increasing the thickness of the antenna module 1. This allows for the adjustment of the phase difference of the RF current between a pair of first radiating arms 101 to achieve linear polarization of the pair of first radiating arms 101, while further achieving a low profile for the antenna module 1. Furthermore, the coplanarity of the second connecting portion 50, the first feed portion 211, and the second feed portion 212 facilitates their formation within the same plane. This allows for adjustment of the phase difference of the RF current between the first feed portion 211 and the second feed portion 212 to achieve linear polarization of the pair of first radiating arms 101, while simultaneously reducing the manufacturing difficulty of the second connecting portion 50 and the first feed component 201, thereby improving the mass production and efficiency of the antenna module 1. Additionally, it allows for a reduction in the overall cross-sectional area of ​​the antenna module 1.

[0089] In one embodiment, the first feed section 211 and the second feed section 212 are arranged opposite to each other along a first direction, and the second connecting section 50 extends along the first direction. It is understood that the first feed section 211, the second connecting section 50, and the second feed section 212 are arranged in a straight line. By arranging the first feed section 211 and the second feed section 212 opposite to each other along the first direction, and the second connecting section 50 extending along the first direction, the phase difference between the RF current of the first feed section 211 and the RF current of the second feed section 212 can be nπ. This also helps to avoid interference between the second connecting section 50 and the first connecting section 30, improves the phase accuracy between the third feed section 202 and the fourth feed section 203, and the phase accuracy between the first feed section 211 and the second feed section 212, thereby giving the pair of first radiating arms 101 and the pair of second radiating arms 102 higher phase accuracy.

[0090] Optional, such as Figure 11As shown, the orthographic projection of the transmission unit 210 onto the plane containing the pair of first radiating arms 101 lies within the region between the orthographic projections of the third feed unit 202 onto the plane containing the pair of first radiating arms 101, the fourth feed unit 203 onto the plane containing the pair of first radiating arms 101, and the first connecting portion 30 onto the plane containing the pair of first radiating arms 101. It can be understood that the third feed unit 202, the fourth feed unit 203, and the first connecting portion 30 surround the outer periphery of the transmission unit 210; that is, along the first direction, the transmission unit 210 is located between the first connecting portion 30, the third feed unit 202, and the fourth feed unit 203; and along the second direction, the transmission unit 210 is similarly located between the first connecting portion 30, the third feed unit 202, and the fourth feed unit 203. By placing the orthographic projection of the feed section 210 onto the plane containing the pair of first radiating arms 101 within the area between the orthographic projections of the third feed section 202 onto the plane containing the pair of first radiating arms 101, the fourth feed section 203 onto the plane containing the pair of first radiating arms 101, and the first connecting section 30 onto the plane containing the pair of first radiating arms 101, the compactness of the arrangement of the first feed section 201, the third feed section 202, and the fourth feed section 203 can be further improved while ensuring that the first feed section 201, the third feed section 202, and the fourth feed section 203 are spaced apart to ensure the isolation requirement. This results in a compact structure and smaller size for the antenna module 1.

[0091] Furthermore, such as Figure 12 As shown, antenna module 1 also includes a grounding component 60. The grounding component 60 can be made of metal, alloy, etc. The grounding component 60 can be connected to electronic device 100 (see reference). Figure 2The middle frame 320 of the electronic device 100 is electrically connected, or the grounding element 60 can be electrically connected to the reference ground of the circuit board 33 of the electronic device 100, or the grounding element 60 can be integrated with the reference ground of the circuit board 33 of the electronic device 100. The grounding element 60 is located on the side of the feeding unit 20 away from the radiating unit 10. In other words, the radiating unit 10, the feeding unit 20, and the grounding element 60 are stacked in sequence. The grounding element 60 covers a pair of first radiating arms 101 and a pair of second radiating arms 102. It is understood that the area of ​​the grounding element 60 is greater than or equal to the sum of the areas of the pair of first radiating arms 101 and the pair of second radiating arms 102. The end of the transmission unit 210 away from the first feeding unit 211 passes through the grounding element 60, the end of the third feeding unit 202 away from the second radiating arm 102 passes through the grounding element 60, and the end of the fourth feeding unit 203 away from the second radiating arm 102 is spaced apart from the grounding element 60. Understandably, the transmission section 210 of the first feed unit 201 extends from the first feed unit 211 away from the antenna module 1 through the grounding member 60 to facilitate electrical connection to the radio frequency signal source; the third feed unit 202 extends from the second radiating arm 102 away from the antenna module 1 through the grounding member 60 to facilitate electrical connection to the radio frequency signal source; the fourth feed unit 203 is located between the grounding member 60 and the second radiating arm 102, and is electrically connected to the second radiating arm 102, with a gap between it and the grounding member 60 to prevent the radio frequency current of the fourth feed unit 203 from directly returning to ground. None of the transmission section 210, the third feed unit 202, or the fourth feed unit 203 are directly electrically connected to the grounding member 60.

[0092] By setting the grounding element 60, the radiated signals of a pair of first radiating arms 101 and a pair of second radiating arms 102 can be reflected, thereby extending the transmission distance of the antenna module 1 and improving the communication performance of the antenna module 1.

[0093] When multiple antenna modules 1 form an antenna array 2, the grounding components 60 of the multiple antenna modules 1 can form an integral grounding component 60.

[0094] Further, please refer to Figure 13 and Figure 14The antenna module 1 further includes a pair of first coupling patches 70 and a pair of second coupling patches 80. The pair of first coupling patches 70 are respectively disposed opposite to and coupled to a pair of first radiating arms 101. The pair of second coupling patches 80 are respectively disposed opposite to and coupled to a pair of second radiating arms 102. It is understood that the pair of first coupling patches 70 are disposed opposite to each other along a first direction, with one first coupling patch 70 being disposed opposite to and coupled to one first radiating arm 101, and the other first coupling patch 70 being disposed opposite to and coupled to the other first radiating arm 101. The pair of second coupling patches 80 are disposed opposite to each other along a second direction, with one second coupling patch 80 being disposed opposite to and coupled to one second radiating arm 102, and the other second coupling patch 80 being disposed opposite to and coupled to the other second radiating arm 102. This application does not specifically limit the shape, size, material, etc., of the first coupling patches 70 and the second coupling patches 80. For example, the shape of the first coupling patch 70 can be circular, square, rectangular, triangular, elliptical, or other polygonal or irregular shapes. The shape of the second coupling patch 80 can be circular, square, rectangular, triangular, elliptical, or other polygonal or irregular shapes. The dimension of the first coupling patch 70 along the first direction can be less than, equal to, or greater than the dimension of the first radiating arm 101 along the first direction; the dimension of the first coupling patch 70 along the second direction can be less than, equal to, or greater than the dimension of the first radiating arm 101 along the second direction. The dimension of the second coupling patch 80 along the first direction can be less than, equal to, or greater than the dimension of the second radiating arm 102 along the first direction; the dimension of the second coupling patch 80 along the second direction can be less than, equal to, or greater than the dimension of the second radiating arm 102 along the second direction.

[0095] The first coupling patch 70 can be made of metal, alloy, etc. The second coupling patch 80 can also be made of metal, alloy, etc. The coupling of the first coupling patch 70 to the first radiating arm 101 can be understood as forming a third coupling gap between the first coupling patch 70 and the first radiating arm 101. The coupling of the second coupling patch 80 to the second radiating arm 102 can be understood as forming a fourth coupling gap between the second coupling patch 80 and the second radiating arm 102. The third and fourth coupling gaps can be the same or different.

[0096] By coupling a pair of first coupling patches 70 to a pair of first radiating arms 101 respectively, the pair of first coupling patches 70 can serve as matching circuits for the pair of first radiating arms 101. This allows for the adjustment of the current distribution of the pair of first radiating arms 101 by designing the structure and position of the pair of first coupling patches 70, thereby improving the radiation effect of the pair of first radiating arms 101 and enhancing the broadband and ultra-wideband characteristics of the antenna module 1. Of course, the pair of first coupling patches 70 can also serve as coupling branches of the pair of first radiating arms 101, participating in radiation to improve the communication performance of the antenna module 1. Similarly, by coupling a pair of second coupling patches 80 to a pair of second radiating arms 102 respectively, the pair of second coupling patches 80 can serve as matching circuits for the pair of second radiating arms 102. This allows for the adjustment of the current distribution of the pair of second radiating arms 102 by designing the structure and position of the pair of second coupling patches 80, thereby improving the radiation effect of the pair of second radiating arms 102 and enhancing the broadband and ultra-wideband characteristics of the antenna module 1. Of course, a pair of second coupling patches 80 can also serve as coupling stubs of a pair of second radiating arms 102 to participate in radiation, thereby improving the communication performance of antenna module 1.

[0097] A pair of first coupling patches 70 are located between the radiating element 10 and the grounding element 60. It is understood that the first radiating arm 101, the first coupling patches 70, and the grounding element 60 are arranged sequentially along the thickness direction of the antenna module 1. The antenna module 1 also includes at least one first coupling grounding element 701 and at least one second coupling grounding element 702. At least one first coupling grounding element 701 is electrically connected between one first coupling patch 70 and the grounding element 60, and at least one second coupling grounding element 702 is electrically connected between another first coupling patch 70 and the grounding element 60. This application does not specifically limit the number of first coupling grounding elements 701 or the number of second coupling grounding elements 702. The number of first coupling grounding elements 701 and the number of second coupling grounding elements 702 can be the same or different. In one possible implementation, there are two first coupling grounding elements 701, which are electrically connected between a first coupling patch 70 and a grounding element 60; there are two second coupling grounding elements 702, which are electrically connected between another first coupling patch 70 and a grounding element 60.

[0098] By positioning a pair of first coupling patches 70 between the radiating element 10 and the grounding element 60, the antenna module 1 can achieve a lower profile. One of the first coupling patches 70 is grounded through a first coupling grounding element 701, allowing the first coupling grounding element 701 to also couple with the first radiating arm 101. This increases the adjustability of the current distribution in the first radiating arm 101, achieving bandwidth diversity in the antenna module 1, and enabling the first coupling grounding element 701 to participate in radiation, thereby improving the communication performance of the antenna module 1. The other first coupling patch 70 is grounded through a second coupling grounding element 702, allowing the second coupling grounding element 702 to also couple with the other first radiating arm 101. This increases the adjustability of the current distribution in the other first radiating arm 101, achieving bandwidth diversity in the antenna module 1, and enabling the second coupling grounding element 702 to participate in radiation, thereby improving the communication performance of the antenna module 1.

[0099] In this configuration, a pair of second coupling patches 80 are located on the side of the radiating element 10 away from the grounding element 60. It is understood that the second coupling patches 80, the second radiating arms 102, and the grounding element 60 are arranged sequentially along the thickness direction of the antenna module 1. Since the pair of second coupling patches 80 are respectively positioned opposite and coupled to the pair of second radiating arms 102, and the first feed section 211 of the fourth feed section 203 is positioned opposite and coupled to one second radiating arm 102, and the second feed section 212 of the fourth feed section 203 is positioned opposite and coupled to the other second radiating arm 102, by positioning the pair of second coupling patches 80 on the side of the radiating element 10 away from the grounding element 60, interference between the pair of second coupling patches 80 and the first feed section 211 and the second feed section 212 can be avoided, thus balancing the feeding effect of the first feed section 211 and the second feed section 212 on the pair of first radiating arms 101 and the adjustment effect of the pair of second coupling patches 80 on the pair of first radiating arms 101.

[0100] The antenna module 1 provided in this application can form a crossed or orthogonal dual-polarized dipole antenna module by designing the first connecting part 30 and the second connecting part 50. The structure of the first connecting part 30 and its arrangement between the first feed part 201, the third feed part 202 and the fourth feed part 203 can realize the phase difference design of the radio frequency current between the third feed part 202 and the fourth feed part 203, thereby realizing the linear polarization of a pair of second radiating arms 102, while improving the compactness of the antenna module 1 and reducing the cross-section of the antenna module 1. The structure of the second connection portion 50 and its arrangement between the first feed portion 211 and the second feed portion 212 enable the design of the phase difference of the RF current between the first feed portion 211 and the second feed portion 212, thereby achieving linear polarization of the pair of first radiating arms 101. Simultaneously, it helps increase the isolation between the second connection portion 50 and the first connection portion 30, preventing interference between them and improving the phase accuracy of the pair of first radiating arms 101 and the pair of second radiating arms 102. The design of the first coupling patch 70 and the second coupling patch 80 can improve the radiation and matching effects of the antenna module 1 while maintaining a low profile, thus giving the antenna module 1 superior radiation performance and widening its bandwidth.
