With the increasing trend toward miniaturization and integration of devices, designing efficient, stable, and minimally interfering antenna assemblies within limited space has become a technical challenge.

[0003] Traditional antenna assembly designs often place multiple antennas closely together on the same plane or in adjacent spaces. This layout can easily lead to increased electromagnetic coupling between antennas, which in turn reduces antenna isolation and radiation efficiency. Especially in complex electromagnetic environments, mutual interference between antennas can significantly affect signal reception and transmission quality, and may even cause communication interruption. Therefore, improving effective isolation between antennas has become a critical issue that needs to be addressed. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

It does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0026] like Figure 1 As shown, an embodiment of the present application provides an antenna assembly, including a housing 11, a circuit board assembly 12, a first antenna assembly 13, and a second antenna assembly 14. The housing 11 has a receiving cavity 113 for accommodating the first antenna assembly 13 and the second antenna assembly 14. The circuit board assembly 12 has a first contact group 121 and a second contact group 122.

[0027] The first antenna assembly 13 and the second antenna assembly 14 are spaced apart. The first antenna assembly 13 is provided with a third contact group 131, and the second antenna assembly 14 is provided with a fourth contact group 141. The first contact group 121 and the third contact group 131 are in contact and conduction, while the second contact group 122 and the fourth contact group 141 are in contact and conduction. The third contact group 131 and the fourth contact group 141 are arranged opposite each other within the accommodating cavity 113 along the diagonal direction of the housing 11. The third contact group 131 and the fourth contact group 141 are arranged opposite each other within the accommodating cavity 113 along the diagonal direction of the housing 11, meaning that in the orthographic projection of the antenna assembly, the third contact group 131 and the fourth contact group 141 are arranged opposite each other within the accommodating cavity 113 along the diagonal direction of the housing 11. The orthographic projection of the antenna assembly is the orthographic projection on a plane perpendicular to the thickness direction of the antenna assembly.

[0028] like Figure 2As shown, housing 11 includes a mating top shell 111 and bottom shell 112. Top shell 111 and bottom shell 112 together define a cavity 113 for accommodating components. Circuit board assembly 12 is closer to top shell 111 than to first antenna assembly 13 and second antenna assembly 14. First contact group 121 and second contact group 122 are disposed on a side surface of circuit board assembly 12 near first antenna assembly 13 and second antenna assembly 14. Third contact group 131 and fourth contact group 141 serve as feed points for first antenna assembly 13 and second antenna assembly 14, respectively, for electrical connection to circuit board assembly 12.

[0029] Since the third contact group 131 and the fourth contact group 141 are arranged opposite to each other in the accommodating cavity 113 along the diagonal direction of the shell 11, the distance between the third contact group 131 and the fourth contact group 141 is lengthened, so that the feeding points of the first antenna component 13 and the second antenna component 14 are further away from each other, effectively improving the isolation between the first antenna component 13 and the second antenna component 14, which is conducive to ensuring signal purity and improving communication quality and stability.

[0030] The antenna assembly provided in the embodiment of the present application arranges the first antenna assembly 13 and the second antenna assembly 14 relative to each other in the accommodating cavity 113 of the shell 11 to achieve physical spatial isolation. This layout reduces the direct coupling path between the antennas. Spatial separation helps to reduce the mutual interference of electromagnetic waves, thereby improving antenna isolation. The third contact group 131 and the fourth contact group 141 are arranged relative to each other along the diagonal direction of the shell 11, which helps to optimize the electromagnetic field distribution inside the antenna assembly and further enhance the spatial isolation effect between the antennas. The diagonal layout makes the radiation patterns of the first antenna assembly 13 and the second antenna assembly 14 as non-overlapping as possible, reduces the electromagnetic coupling between the antennas, thereby improving the isolation, improving the radiation efficiency and directivity of the antenna, and enabling the antenna assembly to operate more stably in a complex electromagnetic environment and achieve optimized reception of signals in different directions or frequency bands.

[0031] For example, the orthographic projection of the housing 11 on a plane perpendicular to its thickness direction is a rectangle. Figure 1 As shown, the outline shapes of the top shell 111 and the bottom shell 112 are both rounded rectangles. Figure 3 As shown, the third contact group 131 and the fourth contact group 141 are arranged along a diagonal line. The diagonal line of a rectangle is the longest line segment within the rectangle. The third contact group 131 and the fourth contact group 141 are arranged opposite each other within the accommodating cavity 113 along the diagonal direction of the housing 11. This maximizes the distance between the third contact group 131 and the fourth contact group 141, further enhancing the antenna isolation between the first antenna assembly 13 and the second antenna assembly 14.

[0032] In an optional embodiment, the first antenna assembly 13 and the second antenna assembly 14 are arranged opposite to each other in the accommodating cavity 113 along the diagonal direction of the housing 11 .

[0033] In this embodiment, the diagonal layout places the first antenna assembly 13 and the second antenna assembly 14 as far away from each other as possible in physical space, thereby maximizing the spatial isolation between them. This layout reduces the direct coupling path between the antennas and reduces mutual interference between the antennas. The diagonal layout also helps optimize the radiation patterns of the first antenna assembly 13 and the second antenna assembly 14. Due to the relative positions of the first antenna assembly 13 and the second antenna assembly 14, the radiation patterns may be more dispersed, reducing overlap in the same direction. This helps reduce electromagnetic coupling between the antennas and improve the radiation efficiency and directivity of the antennas. Within the limited space of the housing cavity 113, the diagonal layout is an effective solution, allowing for a compact design while maintaining appropriate isolation between the antennas. For devices requiring miniaturized, integrated antenna assemblies, the size, shape, and position of the first antenna assembly 13 and the second antenna assembly 14 can be adjusted according to specific application requirements and space limitations to achieve optimal isolation and performance.

[0034] In another optional embodiment, the first antenna assembly 13 and the second antenna assembly 14 are arranged opposite to each other in the accommodating cavity 113 along the length direction of the housing 11 .

[0035] like Figure 3 As shown, the first antenna component 13 and the second antenna component 14 are respectively located at the two ends of the length direction of the shell 11, which increases the distance between the first antenna component 13 and the second antenna component 14, avoiding interference between the first antenna component 13 and the second antenna component 14 due to being too close.

[0036] In this embodiment, the first antenna assembly 13 and the second antenna assembly 14 are arranged relative to each other along the length direction of the shell 11, which helps to control the distance and relative angle between the two during the design and manufacturing process, thereby making it easier to achieve the expected electromagnetic performance and providing sufficient spatial isolation to reduce direct coupling between the antennas.

[0037] like Figure 6 As shown, the first antenna assembly 13 includes a first antenna bracket 132 and a first antenna module 133, and the first antenna module 133 is at least partially covered on the first antenna bracket 132; the thickness direction of the first antenna bracket 132 is perpendicular to the extension direction of the circuit board assembly 12, and the extension direction of the circuit board assembly 12 is perpendicular to the thickness direction of the shell 11.

[0038] The second antenna assembly 14 includes a second antenna support 142 and a second antenna module 143 . The second antenna module 143 is at least partially covered on the second antenna support 142 . The thickness direction of the second antenna support 142 is perpendicular to the extension direction of the circuit board assembly 12 .

[0039] First antenna module 133 and second antenna module 143 are used to transmit and receive electromagnetic waves. First antenna bracket 132 and second antenna bracket 142 provide mounting locations for first antenna module 133 and second antenna module 143. Because second antenna assembly 14 has a similar structure and connection relationship to first antenna assembly 13, the following description will use first antenna assembly 13 as an example to illustrate the technical effects of this embodiment.

[0040] In this embodiment, the first antenna module 133 is encased in the first antenna support 132, forming a stable mechanical structure. This design enhances the securement of the first antenna module 133 and improves its vibration resistance in various operating environments. The vertical layout of the first antenna support 132, which serves as the foundational support structure for the first antenna module 133, may also help reduce electromagnetic coupling between the antenna and the circuit board assembly 12, further improving the antenna's isolation and performance stability.

[0041] Because the extension direction of circuit board assembly 12 is perpendicular to the thickness of housing 11, this layout provides more flexible installation space for the antenna assembly. First antenna assembly 13 can be arranged perpendicular to circuit board assembly 12, enabling compact installation of the antenna assembly without increasing circuit board area. This improves product space utilization and contributes to a smaller and lighter antenna assembly.

[0042] In addition, the antenna assembly often generates a certain amount of heat during operation. By wrapping the first antenna module 133 on the first antenna bracket 132 and reasonably designing the heat dissipation structure of the first antenna bracket 132, the heat generated by the antenna can be effectively extracted and dissipated into the surrounding environment, which helps to reduce the operating temperature of the antenna assembly.

[0043] In one embodiment, first antenna bracket 132 and first antenna module 133 are detachably connected, and second antenna bracket 142 and second antenna module 143 are detachably connected. The first antenna bracket 132 and first antenna module 133, and the second antenna bracket 142 and second antenna module 143, can be connected using threaded connections, snap-fit connections, adhesive connections, or other methods. This helps improve the efficiency of assembly and disassembly of the antenna brackets and antenna modules, and enhances the flexibility and maintainability of first antenna assembly 13 and second antenna assembly 14.

[0044] In one embodiment, the first antenna module 133 is a FPC (Flexible Printed Circuit) antenna. The first antenna module 133 is at least partially attached to the surface of the first antenna bracket 132 to adapt to the shape of the surface of the first antenna bracket 132.

[0045] Due to its flexibility, the FPC antenna can be tightly and flexibly attached to the surface of first antenna bracket 132, even to complex surfaces. This allows first antenna module 133 to better adapt to various installation spaces and layout requirements. Furthermore, the tight attachment of the FPC antenna to the surface of first antenna bracket 132 helps reduce antenna position shifting or performance degradation caused by vibration or mechanical stress.

[0046] In one embodiment, one of the first antenna support 132 and the first antenna module 133 is provided with a protruding positioning post 1321 , and the other is provided with a positioning hole 1331 ; the positioning post 1321 is inserted into the positioning hole 1331 .

[0047] like Figure 6 As shown, first antenna module 133 and second antenna module 143 are provided with positioning holes 1331, and first antenna bracket 132 and second antenna bracket 142 are provided with positioning posts 1321. By inserting positioning posts 1321 into positioning holes 1331, a detachable connection is achieved between first antenna module 133 and first antenna bracket 132, and between second antenna module 143 and second antenna bracket 142.

[0048] In this embodiment, the design of positioning post 1321 and positioning hole 1331 ensures precise alignment of first antenna module 133 when mounted on first antenna support 132, ensuring good contact between first antenna module 133 and first antenna support 132, and reducing performance degradation or signal interference caused by misalignment. Once positioning post 1321 is inserted into positioning hole 1331, the two form a secure mechanical connection, preventing the antenna module from shifting or falling out due to vibration or external forces during use, thereby improving the stability and reliability of the antenna system.

[0049] In one embodiment, a limiting structure 1121 is provided in the housing 11 , and the limiting structure 1121 is used to limit the first antenna bracket 132 .

[0050] like Figure 6As shown, a limiting structure 1121 is protruded from the bottom shell 112 to define an installation space for the first antenna component 13 and the second antenna component 14. After the first antenna component 13 and the second antenna component 14 are assembled in place, the limiting structure 1121 can limit the movement of the first antenna component 13 and the second antenna component 14 to prevent the first antenna component 13 and the second antenna component 14 from moving in the accommodating cavity 113.

[0051] In this embodiment, the limiting structure 1121 can effectively limit the movement or shaking of the first antenna bracket 132 and the second antenna bracket 142 within the housing 11, thereby enhancing their stability. The provision of the limiting structure 1121 can ensure that the antenna bracket remains in a fixed position during device operation, reducing positional deviations caused by external factors such as vibration and impact. The presence of the limiting structure 1121 ensures the stable position of the antenna bracket within the housing, avoiding faults such as poor contact and signal interruption caused by bracket movement. The limiting structure 1121 provides the antenna bracket with a clear installation location and fixing method, making the assembly process simpler and more efficient.

[0052] An embodiment of the present application provides an electronic device, including the antenna assembly, interface assembly 15, and earphone assembly 2 provided in any of the above embodiments, the interface assembly 15 is accommodated in the accommodating cavity 113, the interface assembly 15 includes a first communication interface 151, the earphone assembly 2 includes a second communication interface 21, and the shell 11 is provided with a jack 1122, and the second communication interface 21 can pass through the jack 1122 and be connected to the first communication interface 151.

[0053] like Figure 4 As shown, the interface assembly 15 is fixed to a side surface of the circuit board assembly 12. A socket 1122 is provided in the bottom housing 112 to expose the first communication interface 151 so that the second communication interface 21 is connected to the first communication interface 151 through the socket 1122.

[0054] The earphone assembly 2 includes a microphone and a speaker. The microphone is used to collect sound, and the speaker is used to output sound. When the first communication interface 151 and the second communication interface 21 are connected, the earphone assembly 2 is electrically connected to the circuit board assembly 12 via the interface assembly 15, thereby sending signals to the circuit board assembly 12 or receiving signals sent by the circuit board assembly 12.

[0055] In this embodiment, the first communication interface 151 and the second communication interface 21 are both Universal Serial Bus Type-C interfaces, ie, USB Type-C interfaces.

[0056] In one embodiment, the ground terminal of the first antenna assembly 13 and / or the second antenna assembly 14 is electrically connected to the ground terminal of the interface assembly 15, and the ground terminal of the interface assembly 15 is used to connect to the ground line of the earphone assembly 2. When the first communication interface 151 is connected to the second communication interface 21, the ground terminal of the first antenna assembly 13 and / or the second antenna assembly 14 is electrically connected to the ground line of the earphone assembly 2, so that the first antenna assembly 13 and / or the second antenna assembly 14 can share a common ground with the earphone assembly 2.

[0057] like Figure 5 As shown, the electronic device further includes a processing module 3 and an audio processing module 4 in communication connection. The audio processing module 4 is in communication connection with the first communication interface 151. The GND terminal is the ground terminal of the first communication interface 151 or the second communication interface 21. The GND terminal is used to provide circuit grounding, ensure the stability of the power supply loop, help reduce noise signals that may be generated during transmission, and improve the purity and clarity of the audio signal.

[0058] The ground end of the first antenna component 13 and / or the second antenna component 14 is connected to the GND terminal of the first communication interface 151. When the first communication interface 151 is connected to the second communication interface 21, the first antenna component 13 and / or the second antenna component 14 can share the same ground with the earphone component 2.

[0059] In this embodiment, the earphone assembly 2 has a left channel and a right channel. The earphone cable of the earphone assembly 2 includes a left channel signal line, a right channel signal line, and two ground lines. Specifically, the left channel and the right channel each have one signal line and one ground line. When the first communication interface 151 is connected to the second communication interface 21, the ground terminal of the first antenna assembly 13 and / or the second antenna assembly 14 is connected to the ground line of the earphone cable.

[0060] In related technologies, due to the size limitations of miniaturized electronic devices, the ground loop impedance in the antenna grounding system is relatively high, resulting in signal loss during transmission and reduced antenna sensitivity. Due to space constraints, the antenna's grounding point cannot be used to adjust the impedance to match the impedance of the transmission line. Without a unified ground reference plane, electromagnetic interference between different components is particularly prominent, affecting the antenna's radiation efficiency.

[0061] In the electronic device provided in the embodiment of the present application, at least one of the first antenna assembly 13 and the second antenna assembly 14 is configured to share a common ground with the earphone assembly 2. This can optimize the grounding system of the first antenna assembly 13 and / or the second antenna assembly 14, reduce the impedance of the ground loop, reduce signal loss during transmission, and improve the signal reception sensitivity of the first antenna assembly 13 and / or the second antenna assembly 14. With the reduced ground loop impedance, the first antenna assembly 13 and / or the second antenna assembly 14 can more effectively radiate electromagnetic energy into space, thereby improving its coverage range and signal strength.

[0062] In the electronic device provided in the embodiment of the present application, at least one of the first antenna assembly 13 and the second antenna assembly 14 is configured to share a common ground with the earphone assembly 2. This extends the grounding point of the first antenna assembly 13 and / or the second antenna assembly 14, and can more effectively adjust the antenna impedance to match the impedance of the transmission line, thereby reducing the generation of reflected waves and improving signal transmission efficiency. This also helps to improve the radiation efficiency of the first antenna assembly 13 and / or the second antenna assembly 14.

[0063] In the electronic device provided in the embodiment of the present application, at least one of the first antenna component 13 and the second antenna component 14 is configured to share a common ground with the earphone component 2 to form a unified ground reference plane, which helps to reduce electromagnetic interference between different components and improve signal purity.

[0064] like Figure 7 As shown, the electronic device further includes a battery assembly 5, which is disposed in the accommodating cavity 113 and located between the first antenna assembly 13 and the second antenna assembly 14. The battery assembly 5 is used to power the electronic components of the electronic device.

[0065] The present application also provides a wireless communication terminal, comprising the antenna assembly provided by any of the above embodiments.

[0066] When the first antenna assembly 13 is an LTE antenna and the second antenna assembly 14 is a Bluetooth antenna, the wireless communication terminal can be a public network walkie-talkie or a mobile phone. When the first antenna assembly 13 is a Lora antenna and the second antenna assembly 14 is a Bluetooth antenna, the wireless communication terminal can be an analog walkie-talkie.

[0067] When a wireless communication terminal is equipped with an LTE antenna as the first antenna component 13 and a Bluetooth antenna as the second antenna component 14, the wireless communication terminal generally refers to a device capable of accessing a public mobile communication network, such as a public network walkie-talkie or smartphone. The LTE antenna in public network walkie-talkies and smartphones enables these devices to connect to the operator's 4G / LTE network, thereby enabling long-distance voice communication, data transmission, and internet access. The use of LTE antennas enables public network walkie-talkies to transcend the communication range limitations of traditional walkie-talkies, achieving wider communication coverage and richer functionality.

[0068] Bluetooth antennas enable short-range wireless connections between devices. In public intercoms and smartphones, Bluetooth antennas allow users to pair and communicate with headsets, speakers, other mobile phones, or smart devices via Bluetooth technology. This connection isn't limited to audio transmission; it can also include data transmission and remote control.

[0069] When the first antenna component 13 of the wireless communication terminal is a LoRa antenna and the second antenna component 14 is a Bluetooth antenna, this configuration is more commonly associated with analog walkie-talkies or certain types of low-power wide-area network (LPWAN) devices. LoRa Antenna: LoRa (Long Range Radio) is a wireless communication technology designed for low-power wide-area networks, supporting low-power data transmission over long distances.
