[0036] In the related art, in order to solve the problem of radar antenna loss, various devices and antennas at the antenna RF front end are often integrated together and designed as a packaged antenna module. The use of high-performance chips and packaging processes (such as AiP process, Antenna in package process) can produce an antenna component with a small size and space occupation while ensuring antenna performance. The peripheral auxiliary devices and circuits used to realize the radar antenna function in the antenna assembly are usually arranged on the mainboard of the electronic device and connected to the packaged antenna module through transmission lines to reduce the space occupied by the packaged antenna module. However, the above-mentioned peripheral auxiliary devices and circuits not only occupy the mainboard space, but also are susceptible to interference and reduced performance due to the long distance from the packaged antenna module.

[0037] The present disclosure provides an antenna assembly. Figure 1 is a schematic cross-sectional structure diagram of an antenna assembly in an exemplary embodiment of the present disclosure, Figure 2 is a schematic diagram of the structure of an electronic device in an exemplary embodiment of the present disclosure, such as Figure 1 , Figure 2As shown, the antenna assembly 1 includes an integrated module 11, a transmission line 12 and at least one functional module 13. The integrated module 11 includes an antenna portion 111, and the transmission line 12 includes a main structure 127, a first connection end 121 and a second connection end 122, the first connection end 121 is conductively connected to the integrated module 11, and the second connection end 122 is conductively connected to the device mainboard 21. The functional module 13 is arranged on the main structure 127, and the functional module 13 is conductively connected to the first connection end 121 and the second connection end 122 respectively.

[0038] Since the functional module 13 of the antenna assembly 1 is arranged on the transmission line 12 connecting the integrated module 11 and the device mainboard 21, and is respectively conductively connected to the first connection end 121 and the second connection end 122 of the transmission line 12, the corresponding antenna auxiliary function can be realized. The functional module 13 is arranged on the transmission line 12, which not only avoids occupying the space of the device mainboard 21, but also helps to shorten the distance between the functional module 13 and the integrated module, reduces the interference of external devices on the functional module 13, and improves the antenna performance of the antenna assembly 1 and the electronic device 2 using the antenna assembly 1.

[0039] In the above embodiment, the integrated module 11 can be a millimeter wave radar antenna module or other types of antenna modules, and the present disclosure does not limit this. When the integrated module 11 is a millimeter wave radar antenna module, the millimeter wave radar antenna module encapsulates the millimeter wave radar antenna and the radio frequency chip in a compact module, realizes the close integration of the antenna and the radio frequency circuit, reduces the size of the millimeter wave radar antenna module, helps to improve system performance and simplify the integration process.

[0040] The antenna part 111 of the millimeter wave radar antenna module is used to transmit and receive millimeter wave signals, and usually adopts a high frequency and narrow beam design to achieve high resolution and long-distance detection capabilities. The antenna part 111 may also include a control circuit that can control and manage the working state of the radar module, including power regulation, frequency selection, and data processing.

[0041] The above-mentioned integrated module 11 has a small size, high integration and stable performance, so it can be applied to mobile phones, tablet computers, wearable devices, automotive radars, smart security systems, drones and robots to obtain high-performance millimeter-wave radar functions.

[0042] In the above embodiment, the transmission line 12 can be a flexible transmission line 12, which can be curved and bent without affecting performance, and can adapt to various complex layout and shape requirements. Since the flexible transmission line 12 can be bent and folded in three-dimensional space, it can be connected in a limited space, thereby reducing the size of the system. The flexible transmission line 12 has lower transmission loss and higher frequency response, and is suitable for high-speed digital signal and high-frequency analog signal transmission. The material of the flexible transmission line 12 includes one of LCP, MPI and PI.

[0043] In some embodiments, the transmission line 12 may include a first region 123 close to the integrated module 11, and at least one functional module 13 is disposed in the first region 123, so as to reduce interference between the functional module 13 and external devices by being close to the integrated module 11, and improve the antenna performance of the functional module 13 working with the integrated module 11. For example, the first region 123 is an end section of the transmission line 12, the first connection end 121 is located at one end of the end section, and the first connection end 121 can be conductively connected to the integrated module 11 through a BTB (Board-to-Board Connector) connector.

[0044] In some embodiments, the antenna assembly 1 includes a plurality of functional modules 13 , which are sequentially arranged along the extension direction of the transmission line 12 from the first connection end 121 to the second connection end 122 to improve the utilization rate of the main structure 127 of the transmission line 12 .

[0045] Among them, the functional module 13 may include at least one of a flash memory 133, a level converter 132, and a crystal oscillator 131. For example, when the antenna assembly 1 includes a flash memory 133, a level converter 132, and a crystal oscillator 131, the crystal oscillator 131, the level converter 132, and the flash memory 133 may be arranged from the first connection end 121 to the second connection end 122 at one time to improve the utilization rate of the main structure 127 of the transmission line 12. Multiple functional modules 13 may be arranged according to their association with the integrated module 11, and the functional module 13 with a greater association with the integrated module 11 may be closer to the first connection end 121 to improve the working performance of the corresponding functional module 13.

[0046] In some embodiments, at least two functional modules 13 are arranged side by side in a direction perpendicular to the extension direction. According to the size of the main structure 127 perpendicular to the extension direction and the functions of the functional modules 13, the functional modules 13 can be arranged side by side in the direction perpendicular to the extension, so that the distance between the at least two functional modules 13 arranged side by side in the direction perpendicular to the extension and the integrated module 11 is close, thereby increasing the number of functional modules 13 with improved performance.

[0047] In the above embodiment, a preset interval can be set between adjacent functional modules 13 to avoid structural and functional interference between adjacent functional modules 13, and at the same time enable the functional modules 13 to form a stable structural layout on the main structure 127 to avoid problems such as insufficient strength and rigidity of the local main structure 127.

[0048] It should be noted that the main structure 127 can be a regular rectangular strip structure, or an irregular shape including a local protruding structure, a recessed structure, a bent structure, etc., and the present disclosure is not limited to this.

[0049] In some embodiments, the antenna assembly 1 may further include an auxiliary circuit 14 conductively connected to the functional module 13, the transmission line 12 includes a second area 124 close to the device mainboard 21, and the auxiliary circuit 14 is arranged in the second area 124. Since the functional module 13 is more susceptible to interference from external devices than the auxiliary circuit 14, arranging the auxiliary circuit 14 in the second area 124 close to the device mainboard 21 can not only further reduce the space occupied by the auxiliary circuit 14 on the device mainboard 21, but also reduce the space occupied by the auxiliary circuit 14 on the side close to the integrated module 11.

[0050] The second region 124 may be another end section of the transmission line 12 , and the second connection end 122 is located at one end of the end section. The second connection end 122 may be conductively connected to the device mainboard 21 via a BTB (Board-to-Board Connector) connector.

[0051] The main structure 127 may include a first side surface 125 and a second side surface 126 that are opposite to each other. The first connection end 121 and the second connection end 122 may be disposed on the same side surface or different sides of the main structure 127. The functional module 13 and at least one of the first connection end 121 and the second connection end 122 are located on different sides to increase the area of ​​the functional module 13. For example, the first connection end 121 is disposed at one end of the first side surface 125, the functional module 13 is disposed at the first side surface 125, and the second connection end 122 is located at the other end opposite to the first connection end 121 and disposed at the second side surface 126.

[0052] In the above embodiment, the antenna part 111 may include an antenna array and a transceiver. The antenna array is an integral structure composed of multiple antenna elements arranged in a certain geometric manner. Each antenna element can work independently, and can also work collectively through phase control and signal synthesis. The antenna array can change the radiation characteristics of the antenna system and improve the performance of signal reception and transmission. By controlling the phase and amplitude of each antenna element, it can realize functions such as directional radiation, beam forming, and spatial spectrum analysis. The antenna array cooperates with the transceiver to realize the transmission and reception of antenna radiation signals and realize the corresponding antenna functions.

[0053] In some embodiments, Figure 3 As shown, the antenna assembly 1 may also include a radio frequency part 112, and the radio frequency part 112 is arranged on the main structure 127 to further reduce the size of the integrated module 11, while avoiding the space occupation of the device mainboard 21, thereby improving the installation convenience and antenna performance of the antenna assembly 1. Among them, the radio frequency part 112 can be close to the first connection end 121 and arranged on one side of the functional module 13 to improve the working performance of the corresponding radio frequency part 112. Alternatively, the radio frequency part 112 can also be close to the second connection end 122 and arranged on the other side of the functional module 13. Alternatively, the radio frequency part 112 can also be between the first connection end 121 and the second connection end 122, and between the two functional modules 13.

[0054] In other embodiments, Figure 4 As shown, the integrated module 11 also includes a RF part 112 conductively connected to the antenna part 111. Setting the RF part 112 in the integrated module 11 can enhance the integration of the antenna assembly 1, so that the RF part 112 is close to the antenna part 111, and the performance of the RF part 112 and the antenna assembly 1 is improved.

[0055] In some other embodiments, the device mainboard 21 includes a RF part 112, which is conductively connected to the functional module 13 and the antenna part 111. Setting the RF part 112 on the device mainboard 21 can also realize the function of the antenna assembly 1, and can also effectively utilize the space of the device mainboard 21 and optimize the main structure 127 and the device layout in the integrated module 11.

[0056] The RF part 112 is used for signal amplification, filtering, mixing and other processing, and is usually composed of a RF amplifier, a low noise amplifier, a mixer and a filter, etc., and is used to process the signal from the antenna. The RF part 112 can be a RF chip, which includes a RF circuit and a RF device conductively connected to the RF circuit, and is responsible for signal amplification, filtering, mixing and other processing, and can be composed of a RF amplifier, a low noise amplifier, a mixer and a filter, etc., and is used to process the signal from the antenna.

The radar signals coming out of the integrated module 11 are all very low-frequency signals with low losses. In other peripheral circuits except the integrated module 11, the crystal oscillator 131 uses its output oscillation frequency to ensure the stability of the millimeter wave transmission module, and the flash memory 133 chip (Flash) is used to store radar information or codes. The level converter is responsible for converting the 1.8V power supply commonly used in the electronic device 2 into the 3V power supply required by the integrated module 11.

The functional module 13 is arranged on the transmission line 12, which not only avoids occupying the space of the device mainboard 21, but also helps to shorten the distance between the functional module 13 and the integrated module, reduces the interference of external devices on the functional module 13, and improves the antenna performance of the antenna assembly 1 and the electronic device 2 using the antenna assembly 1.
