[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0041] According to the first aspect of this application, please refer to Figure 1 , Figure 2 and Figure 5 This disclosure provides an antenna module. The antenna module includes a PCB board 1, a positioning module antenna 2, and at least two sets of antenna structures 3. The positioning module antenna 2 is mounted on the PCB board 1, and the at least two sets of antenna structures 3 are also mounted on the PCB board 1. Each set of antenna structures 3 includes at least two antennas 31, and the at least two antennas 31 of each set of antenna structures 3 are disposed on both sides of the positioning module antenna 2.

[0042] It is understandable that mounting the positioning module antenna 2 and at least two sets of antenna structures 3 on the same PCB board 1, i.e., integrating the positioning module antenna 2 and at least two sets of antenna structures 3 simultaneously on the PCB board 1, improves the integration of the antenna module. Furthermore, at least two antennas 31 of each set of antenna structures 3 are positioned on opposite sides of the positioning module antenna 2, with a gap between the two antennas 31 of each set of positioning module antennas 2, achieving isolation between different antennas 31 and reducing coupling between antennas 31. In other words, this application integrates the positioning module antenna 2 and at least two sets of antenna structures 3 by positioning at least two antennas 31 on different sides of the positioning module. While improving the integration of the antenna module, the positioning module antenna 2 can separate at least two antennas 31 of each set of antenna structures 3, effectively reducing coupling and mutual interference between antennas 31.

[0043] In some examples, the two sides of the positioning module antenna 2 can refer to the two adjacent sides of the positioning module antenna 2 or the two opposite sides of the positioning module antenna 2.

[0044] In some examples, at least one antenna 31 of at least one set of antenna structures 3 is in the form of a monopole antenna, which can reduce the mutual coupling of surface currents of antenna 31 and reduce mutual interference / coupling between antennas 31.

[0045] In some embodiments, see Figure 2 The PCB board 1 includes a first end and a second end that are arranged opposite to each other. The at least two antennas 31 of the antenna structure 3 include a first antenna 311 and a second antenna 312. The first antenna 311 is located at the first end and the second antenna 312 is located at the second end.

[0046] It is understandable that by setting the first antenna 311 and the second antenna 312 at opposite ends of the PCB board 1, the distance between the first antenna 311 and the second antenna 312 is ensured, the isolation effect between the first antenna 311 and the second antenna 312 is improved, and the problem of mutual interference between the first antenna 311 and the second antenna 312 can be effectively avoided.

[0047] In some examples, PCB 1 includes a first end and a second end along its length. Alternatively, PCB 1 may include a first end and a second end along its width.

[0048] Specifically, the first antenna 311 and the second antenna 312 of all antenna structures 3 can be distributed along the length direction of the PCB board 1, or the first antenna 311 and the second antenna 312 of all antenna structures 3 can be distributed along the width direction of the PCB board 1, or the first antenna 311 and the second antenna 312 of a portion of the antenna structures 3 can be distributed along the length direction of the PCB board 1, while the first antenna 311 and the second antenna 312 of another portion of the antenna structures 3 can be distributed along the width direction of the PCB board 1.

[0049] In some examples, the first antenna 311 and the second antenna 312 of one set of antenna structures 3 may be respectively set at the first end and the second end, or the two antennas 31 of two or more sets of antenna structures 3 may be respectively set at the first end and the second end.

[0050] In some embodiments, see Figure 2 The first antenna 311 and the second antenna 312 are asymmetrically arranged.

[0051] It is understandable that the asymmetrical arrangement of the first antenna 311 and the second antenna 312 can increase the distance between the first antenna 311 and the second antenna 312, reduce the coupling between the first antenna 311 and the second antenna 312, and reduce the mutual interference between the first antenna 311 and the second antenna 312.

[0052] In some examples, the asymmetrical arrangement of the first antenna 311 and the second antenna 312 refers to the asymmetrical arrangement of the first antenna 311 and the second antenna 312 relative to the centerline of the PCB board 1. This can also be understood as the line connecting the first antenna 311 and the second antenna 312 along the length of the PCB board 1 not being perpendicular to the width edge of the PCB board 1.

[0053] In some examples, the first antenna 311 and the second antenna 312 are respectively located at two diagonal corners of the PCB board 1.

[0054] In some examples, the first antenna 311 and the second antenna 312 of all antenna structures 3 may be asymmetrically arranged, or the first antenna 311 and the second antenna 312 of a portion of antenna structures 3 may be asymmetrically arranged, while the first antenna 311 and the second antenna 312 of another portion of antenna structures 3 may be symmetrically arranged.

[0055] In some embodiments, see Figure 3 At least one antenna 31 includes a feed section, the PCB board 1 includes a ground section 11, and the antenna module also includes a coaxial cable. The inner core of the coaxial cable is connected to the feed section, and the outer conductor of the coaxial cable is connected to the ground section 11.

[0056] It is understandable that using coaxial cable feeding can effectively reduce the mutual coupling and interference between antennas 31.

[0057] In some examples, each antenna 31 is fed by a coaxial line, that is, each antenna 31 is provided with a feeding part, and the PCB board 1 is provided with multiple grounding parts 11. The multiple grounding parts 11 correspond one-to-one with the feeding parts of the multiple antennas 31, and the feeding part of each antenna 31 and the corresponding grounding part 11 are connected by a coaxial line.

[0058] In some examples, the side of the PCB board 1 facing away from the positioning module antenna 2 is covered with a copper layer. The grounding part 11 is covered with a copper layer, and the surface of the copper layer at the grounding part 11 is provided with a nickel layer and a gold layer to protect the grounding area.

[0059] In some embodiments, the antenna module further includes an antenna isolation component and a chip. The antenna isolation component is disposed between either the antenna 31 or the positioning module antenna 2 and the chip to increase the antenna isolation between the antenna 31 and the positioning module antenna 2 or between the two antennas 31.

[0060] It is understandable that the antenna isolation component can filter / isolate signals in specific frequency bands that are not needed. Placing the antenna isolation component between the antenna 31 and the chip, and / or between the positioning module antenna 2 and the chip, can effectively increase the antenna isolation between the antenna 31 and the positioning module antenna 2, and / or the antenna isolation between the two antennas 31.

[0061] In some examples, the antenna isolation component is, for example, a filter or filtering circuit or a directional coupler.

[0062] In some embodiments, see Figure 1 Antenna structure 3 is perpendicular to PCB board 1.

[0063] It is understandable that the antenna structure 3 is perpendicular to the PCB board 1, which can ensure the isolation space between the antennas 31 and reduce the coupling between the antennas 31.

[0064] The antenna structure 3 is perpendicular to the PCB board 1, which ensures that the distance between different positions of the two antennas 31 is the same, thus ensuring the isolation effect.

[0065] In some embodiments, the antenna structure 3 is inserted into the PCB board 1.

[0066] It is understandable that mounting the antenna structure 3 onto the PCB board 1 via insertion makes the installation of the antenna structure 3 more convenient.

[0067] In some examples, see Figure 3 The PCB board 1 has multiple insertion holes 12, each corresponding to an antenna 31. That is, each antenna 31 has a corresponding insertion hole 12. The antenna 31 can be installed by inserting it into the corresponding insertion hole 12.

[0068] In some embodiments, see Figure 1 An antenna structure 3 includes at least a first 5G high-frequency antenna 32 and a second 5G high-frequency antenna 33.

[0069] It is understandable that integrating the first 5G high-frequency antenna 32 and the second 5G high-frequency antenna 33 onto the PCB board 1 improves the integration of the antenna module and enables the antenna module to have 5G communication capabilities.

[0070] In some examples, one of the first 5G high-frequency antenna 32 and the second 5G high-frequency antenna 33 is a receiving antenna, and the other of the first 5G high-frequency antenna 32 and the second 5G high-frequency antenna 33 is a transmitting antenna.

[0071] In some examples, both the first 5G high-frequency antenna 32 and the second 5G high-frequency antenna 33 have transmitting capabilities, and both have receiving capabilities.

[0072] In some examples, one of the first 5G high-frequency antenna 32 and the second 5G high-frequency antenna 33 has a transmitting function, and both the first 5G high-frequency antenna 32 and the second 5G high-frequency antenna 33 have a receiving function.

[0073] In some examples, 5G high-frequency antennas include 2x2 MIMO antennas ranging from 2.515 GHz to 3.6 GHz.

[0074] In some embodiments, see Figure 1 An antenna structure 3 includes at least a first WiFi / Bluetooth antenna 34 and a second WiFi / Bluetooth antenna 35.

[0075] It is understandable that integrating the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35 onto the PCB board 1 improves the integration of the antenna module, enabling the antenna module to have WiFi / Bluetooth functionality.

[0076] In some examples, one of the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35 is a receiving antenna, and the other of the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35 is a transmitting antenna.

[0077] In some examples, both the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35 have transmitting capabilities, and both have receiving capabilities.

[0078] In some examples, one of the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35 has a transmitting function, and both the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35 have a receiving function.

[0079] In some cases, the WiFi / Bluetooth antenna includes a 2x2 MIMO antenna ranging from 2.4 GHz to 2.484 GHz.

[0080] In some embodiments, see Figure 1 The routing of the first 5G high-frequency antenna 32 and the second 5G high-frequency antenna 33 is different.

[0081] It is understandable that the different routing methods of the first 5G high-frequency antenna 32 and the second 5G high-frequency antenna 33 can improve the isolation between the first 5G high-frequency antenna 32 and the second 5G high-frequency antenna 33 and reduce the mutual interference between the first 5G high-frequency antenna 32 and the second 5G high-frequency antenna 33.

[0082] In some examples, the routing of the first 5G high-frequency antenna 32 and the second 5G high-frequency antenna 33 is different, which means that the cables or wires of the first 5G high-frequency antenna 32 and the second 5G high-frequency antenna 33 are arranged differently.

[0083] In some examples, the first 5G high-frequency antenna 32 is designed as a vertically oriented inverted V-shaped monopole trace with an electrical length of 1 / 4 of the wavelength of the operating frequency band, which can achieve better signal transmission / reception functions.

[0084] The second 5G high-frequency antenna 33 is designed with a vertically oriented inverted J-shaped monopole trace, with an electrical length of 1 / 4 of the operating frequency band wavelength, which can achieve better signal transmission / reception functions.

[0085] In some embodiments, the routing of the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35 is different.

[0086] It is understandable that the different routing methods of the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35 can improve the isolation between the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35 and reduce the mutual interference between the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35.

[0087] In some examples, the wiring of the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35 is different, which means that the cables or wires of the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35 are arranged differently.

[0088] In some examples, the first WiFi / Bluetooth antenna 34 is designed as a vertically bent hook-shaped monopole trace with an electrical length of 1 / 4 of the wavelength of the operating frequency band, which can achieve better signal transmission / reception.

[0089] The second WiFi / Bluetooth antenna 35 is designed as a vertically oriented monopole trace in a figure-five shape, with an electrical length of 1 / 4 of the operating frequency band wavelength, which can effectively realize the signal transmission / reception function.

[0090] In some embodiments, see Figure 1Along the width direction of PCB board 1, PCB board 1 includes a first side and a second side. A first 5G high-frequency antenna 32 is disposed on the first side, a second 5G high-frequency antenna 33 is disposed on the second side, a first WiFi / Bluetooth antenna 34 is disposed on the first side, and a second WiFi / Bluetooth antenna 35 is disposed on the second side.

[0091] Understandably, by placing the first 5G high-frequency antenna 32 and the second 5G high-frequency antenna 33 on opposite sides of the PCB board 1, the distance between the first 5G high-frequency antenna 32 and the second 5G high-frequency antenna 33 is ensured, improving the isolation effect between them and effectively preventing mutual interference.

[0092] The first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35 are respectively disposed on both sides of the PCB board 1, which ensures the distance between the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35, improves the isolation effect between the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35, and can effectively avoid the problem of mutual interference between the first WiFi / Bluetooth antenna 34 and the second WiFi / Bluetooth antenna 35.

[0093] In some embodiments, see Figure 1 An antenna structure 3 includes at least a first 5G multi-band antenna 36 and a second 5G multi-band antenna 37.

[0094] It is understandable that integrating the first 5G multi-band antenna 36 and the second 5G multi-band antenna 37 onto the PCB board 1 improves the integration of the antenna module and enables the antenna module to have 5G communication capabilities.

[0095] In some examples, one of the first 5G multi-band antenna 36 and the second 5G multi-band antenna 37 is a receiving antenna, and the other of the first 5G multi-band antenna 36 and the second 5G multi-band antenna 37 is a transmitting antenna.

[0096] In some examples, both the first 5G multi-band antenna 36 and the second 5G multi-band antenna 37 have transmitting capabilities, and both have receiving capabilities.

[0097] In some examples, one of the first 5G multi-band antenna 36 and the second 5G multi-band antenna 37 has a transmitting function, and both the first 5G multi-band antenna 36 and the second 5G multi-band antenna 37 have a receiving function.

[0098] In some examples, 5G multi-band antennas include 2x2 MIMO antennas covering four frequency bands: 0.698GHz-0.96GHz, 1.447GHz-1.511GHz, 1.71GHz-2.69GHz, and 3.3GHz-5GHz.

[0099] The 0.698GHz-0.96GHz band is formed by vertically oriented monopoles, with an electrical length of 1 / 4 of the operating wavelength. The 3.3GHz-5GHz band is achieved by a wedge-shaped section near the feed area, with an electrical length of 1 / 4 of the operating wavelength. The monopole antenna is formed by two branches in a wedge shape with irregular wiring, covering not only the low-frequency 0.698GHz-0.96GHz and high-frequency 3.3GHz-5GHz, but also the 1.447GHz-1.511GHz and 1.71GHz-2.69GHz bands, covering four bands and achieving good signal transmission / reception capabilities. Simultaneously, the 5G multi-band 2x2 MIMO antenna design uses a monopole form, providing good isolation.

[0100] In some examples, 5G multi-band antennas employ a monopole multi-stub structure design to achieve coverage of multiple frequency bands.

[0101] In some examples, the first 5G multi-band antenna 36 and the second 5G multi-band antenna 37 are symmetrically distributed, and antenna 31 is also completely identical.

[0102] In some embodiments, see Figure 1 An antenna structure 3 includes at least a first V2X antenna 38 and a second V2X antenna 39.

[0103] It is understandable that integrating the first V2X antenna 38 and the second V2X antenna 39 onto the PCB board 1 improves the integration of the antenna module and enables the antenna module to have wireless communication capabilities.

[0104] In some examples, one of the first V2X antenna 38 and the second V2X antenna 39 is a receiving antenna, and the other of the first V2X antenna 38 and the second V2X antenna 39 is a transmitting antenna.

[0105] In some examples, both the first V2X antenna 38 and the second V2X antenna 39 have transmitting capabilities, and both have receiving capabilities.

[0106] In some examples, one of the first V2X antenna 38 and the second V2X antenna 39 has a transmitting function, and both the first V2X antenna 38 and the second V2X antenna 39 have a receiving function.

[0107] In some examples, V2X antennas include 2x2 MIMO antennas ranging from 5.905 GHz to 5.925 GHz.

[0108] In some embodiments, along the length of the PCB board 1, the PCB board 1 includes a first end and a second end, a first 5G multi-band antenna 36 and a first V2X antenna 38 are disposed at the first end, and a second 5G multi-band antenna 37 and a second V2X antenna 39 are disposed at the second end.

[0109] It is understandable that by placing the first 5G multi-band antenna 36 and the second 5G multi-band antenna 37 at opposite ends of the PCB board 1, the distance between the first 5G multi-band antenna 36 and the second 5G multi-band antenna 37 is ensured, the isolation effect between the first 5G multi-band antenna 36 and the second 5G multi-band antenna 37 is improved, and the problem of mutual interference between the first 5G multi-band antenna 36 and the second 5G multi-band antenna 37 can be effectively avoided.

[0110] The first V2X antenna 38 and the second V2X antenna 39 are respectively set at both ends of the PCB board 1, which ensures the distance between the first V2X antenna 38 and the second V2X antenna 39, improves the isolation effect between the first V2X antenna 38 and the second V2X antenna 39, and can effectively avoid the problem of mutual interference between the first V2X antenna 38 and the second V2X antenna 39.

[0111] In some embodiments, see Figure 4 The positioning module antenna 2 includes a first frequency band layer 21 and a second frequency band layer 22. The first frequency band layer 21 and the second frequency band layer 22 correspond to different frequency bands. The first frequency band layer 21 is mounted on the PCB board 1, and the second frequency band layer 22 is connected to the side of the first frequency band layer 21 that is away from the PCB board 1.

[0112] It is understandable that the first frequency band layer 21 and the second frequency band layer 22 of different frequency bands are connected in sequence to form the positioning module antenna 2, so that the positioning module antenna 2 can achieve a better positioning function.

[0113] In some examples, the first frequency band layer 21 is, for example, an L5 band antenna, and the second frequency band layer 22 is, for example, an L1 band antenna.

[0114] In some examples, the positioning module antenna 2 uses a ceramic antenna substrate, and the first frequency band layer 21 and the second frequency band layer 22 are stacked together in a stacking manner.

[0115] In some embodiments, see Figure 4The positioning module antenna 2 includes a mounting hole 23 and at least two through holes 24. The at least two through holes 24 are arranged around the mounting hole 23. The at least two through holes 24 include a first feed hole and a second feed hole. The line connecting the center of the first feed hole and the center of the mounting hole 23 is perpendicular to the line connecting the center of the second feed hole and the center of the mounting hole 23.

[0116] It is understandable that the positioning module antenna 2 is mounted on the PCB board 1 using the middle mounting hole 23, while the two through holes 24 with a phase difference of 90 degrees, namely the first feed hole and the second feed hole, are used for feeding, so that the positioning module antenna 2 can achieve good circular polarization and the phase center has high stability.

[0117] In some examples, the L1 band is an upper-layer ceramic antenna, made of ceramic substrate with a silver layer printed on the upper surface. The grooves in the silver layer are used to fine-tune the operating frequency range of the antenna 31, and the entire lower surface of the upper-layer ceramic antenna is covered with the silver layer. For precise positioning, a multi-feed method is used. The upper-layer ceramic antenna has five through holes 24. The central hole is used for mounting and fixing, and the two smallest holes are used for feeding with a 90-degree phase difference, which can achieve good circular polarization and the phase center has high stability.

[0118] The L5 band is the lower-layer ceramic antenna, made of ceramic substrate with a silver layer printed on the upper surface. Several grooves in the silver layer are used to fine-tune the operating frequency range of antenna 31. The entire lower surface of the lower-layer ceramic antenna is covered with the silver layer. For precise positioning, a multi-feed method is used. The lower-layer ceramic antenna has five through holes 24. The central hole is used for mounting and fixing, and the two largest holes are used for feeding with a 90-degree phase difference, which can achieve better circular polarization and high stability of the phase center.

[0119] The five through holes on both the upper and lower ceramic antennas are highly consistent in position and size, facilitating installation and power supply.

[0120] According to a second aspect of this application, this disclosure provides a vehicle. The vehicle includes an antenna module as described above.

[0121] It is understood that the vehicle includes an antenna module, which mounts the positioning module antenna 2 and at least two sets of antenna structures 3 on the same PCB board 1. That is, the positioning module antenna 2 and at least two sets of antenna structures 3 are integrated simultaneously on the PCB board 1, improving the integration of the antenna module. Furthermore, at least two antennas 31 of each set of antenna structures 3 are positioned on both sides of the positioning module antenna 2, and the two antennas 31 of each set of positioning module antennas 2 are spaced apart by the positioning module antenna 2, achieving isolation between different antennas 31 and reducing the coupling between antennas 31. In other words, this application integrates the positioning module antenna 2 and at least two sets of antenna structures 3 by positioning at least two antennas 31 on different sides of the positioning module. While improving the integration of the antenna module, the positioning module antenna 2 can separate at least two antennas 31 of each set of antenna structures 3, effectively reducing the coupling between antennas 31 and reducing mutual interference between antennas 31, thereby ensuring the normal operation of the vehicle's antennas 31.

[0122] In some examples, the vehicle may be a gasoline-powered vehicle, a plug-in hybrid vehicle, or a new energy vehicle, etc., and this disclosure does not specifically limit it.
