[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on January 22, 2024, with application number 202410087081.7 and application name "A feeding network system, antenna, base station and communication system", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of communication technology, and in particular to a feeding network system, an antenna, a base station, and a communication system. Background Art

[0004] With the development of mobile communications, the usage rate of mobile terminals is increasing. Mobile cellular network coverage is crucial for mobile communications. Since antennas are key components in mobile cellular networks, to meet varying network coverage requirements, antennas typically use electronic tilt systems to adjust signal coverage. Currently, to adjust antenna coverage and optimize signal coverage, the antenna's signal radiation tilt is typically adjusted. Adjusting the antenna's signal radiation tilt typically involves using phase shifters to alter the antenna array's phase distribution, thereby adjusting the antenna's radiation pattern and thus adjusting signal coverage.

[0005] Phase shifters use a power mechanism to drive the dielectric to change the relative position of the dielectric and the stripline, thereby altering the dielectric constant of the signal transmission path within the phase shifter. This allows the antenna signal to experience a phase delay or advance as it passes through the phase shifter, thereby adjusting the directionality of the antenna's signal radiation. However, the power mechanisms currently used in phase shifters are large and heavy, failing to meet the demands for miniaturization and lightweighting of antennas. Summary of the Invention

[0006] The present application provides a feeding network system, an antenna, a base station, and a communication system to achieve a miniaturized and lightweight design of the antenna.

[0007] In a first aspect, the present application provides a feed network system, which includes a feed network and a power mechanism. The feed network includes a first shell, a fixed part and a sliding part, the fixed part and the sliding part are accommodated in the first shell, the fixed part is connected to the first shell, and the fixed part is provided with a functional circuit. The power mechanism includes a driving device, which is used to drive the sliding part to slide relative to the fixed part to change the electrical parameters of the functional circuit. In the feed network system provided by the present application, by adopting an integrated design of the feed network and the power mechanism, it is beneficial to improve the degree of integration of the feed network system, thereby facilitating the miniaturization design of the feed network system.

[0008] In one possible implementation of the present application, the fixing member, the sliding member, and the driving device are integrated, which is beneficial to improving the integration of the feed network system, thereby meeting the design requirements of miniaturization and lightweight of the feed network system.

[0009] In one possible implementation of the present application, the power mechanism further includes a second housing, the drive device is mounted in the second housing, and the second housing is fixedly connected to the first housing. This facilitates connection between the power mechanism and the feed network and reduces leakage of magnetic signals that may be generated in the power mechanism, thereby reducing interference with antenna radiation signals caused by the power mechanism.

[0010] In one possible implementation of the present application, the driving device and the sliding member can be directly connected, that is, the driving device and the sliding member can be directly contacted and transmission-connected, so that the force output by the driving device can be directly transmitted to the sliding member, which is beneficial to improving the transmission efficiency of the force between the driving device and the sliding member, and is beneficial to reducing the volume of the feeding network system.

[0011] In a possible implementation of the present application, a first groove is provided on the end surface of the first shell facing the second shell, and a second groove is provided on the end surface of the second shell facing the first shell. The first groove and the second groove are arranged relative to each other, so that the driving device can be connected to the sliding member through the first groove and the second groove, which is conducive to improving the convenience of connecting the driving device and the sliding member.

[0012] In one possible implementation of the present application, a portion of the sliding member is located in the second housing, and the driving device is connected to the portion of the sliding member located in the second housing. This allows the feed network and the power mechanism to be designed more compactly, thereby reducing the overall volume of the feed network system.

[0013] In the present application, the driving device may adopt a variety of possible configurations, which are exemplarily described below.

[0014] In one possible implementation of the present application, the drive device includes a resonant component, which includes a metal elastomer and a piezoelectric material layer. The piezoelectric material layer is disposed on at least one surface of the metal elastomer, and the metal elastomer includes a driving foot that presses against a sliding member, and the driving foot can be used to drive the sliding member to slide. In the present application, the drive device utilizes piezoelectric drive to convert the microscopic motion of the metal elastomer into the macroscopic motion of the sliding member. Due to the small size of the drive device, it facilitates the reduction of the size of the power mechanism, thereby enabling the miniaturization of the feed network system.

[0015] In this implementation, the resonant component also includes a power supply module, which is used to apply a voltage to the piezoelectric material layer so that the piezoelectric material layer drives the metal elastomer to deform according to a set rule under the action of the corresponding voltage. In the present application, the voltage applied to the piezoelectric material layer can be adjusted to adjust the motion law of the metal elastomer, thereby adjusting the motion trajectory of the sliding member driven by the metal elastomer. It can be understood that the drive device designed based on the piezoelectric drive principle provided by the present application can facilitate the adjustment of the motion trajectory of the sliding member, which is conducive to improving the flexibility of the integrated design of the power mechanism and the feed network.

[0016] Furthermore, the drive device of the aforementioned embodiment further includes a positive preload assembly, which is used to apply elastic force to press the driving foot of the metal elastic body toward the sliding member. This effectively increases the contact friction between the driving foot and the sliding member, thereby improving the reliability of the metal elastic body in driving the sliding member.

[0017] Based on the design of the aforementioned drive device, the power mechanism may further include a follower, located between the driving foot and the sliding member, with the driving foot, formed of a metal elastic body, pressing against the follower. The follower is connected to the sliding member, and the driving foot can be used to drive the follower to cause the sliding member to slide. In this implementation, by using the follower as an adapter between the drive device and the sliding member, the flexibility of the connection between the drive device and the sliding member can be enhanced.

[0018] The connection between the follower and the slider can be implemented in a variety of ways. For example, the end of the follower facing the slider includes a gear, and the end of the slider facing the follower includes a rack surface. This allows the gear surface of the gear meshing with the rack surface to achieve a transmission connection between the follower and the slider. Furthermore, in this implementation, providing a rack surface on the slider that meshes with the gear facilitates improved compactness of the feed network system, thereby reducing the size of the feed network system.

[0019] Alternatively, the end of the follower facing the slider includes a protrusion, while the end of the slider facing the follower includes a groove, so that the follower and the slider are connected by inserting the protrusion into the groove. This can help reduce the distance between the follower and the slider, thereby facilitating a miniaturized design of the feed network system.

[0020] In another possible implementation of the present application, the drive device includes a micromotor. Furthermore, the power mechanism also includes a gear. The end of the sliding member facing the gear includes a rack surface, and the gear surface of the gear meshes with the rack surface. The micromotor is used to drive the gear to rotate, thereby causing the gear to drive the sliding member to move. In this implementation, providing a rack surface on the sliding member that meshes with the gear facilitates improving the compactness of the feed network system, thereby facilitating a reduction in the size of the feed network system.

[0021] In another possible implementation of the present application, the drive device includes a micromotor, the power mechanism also includes a worm gear, and the sliding member includes a worm. The worm gear and the worm gear mesh with each other, and the micromotor is used to drive the worm gear to rotate. The worm gear can then drive the worm gear to move, thereby achieving the drive device driving the sliding member to move relative to the fixed member. In this implementation, by providing the worm gear on the sliding member, the compactness of the feed network system is improved, thereby facilitating a reduction in the size of the feed network system.

[0022] In another possible implementation of the present application, the drive device includes a micromotor, the power mechanism also includes a worm, the end of the slider facing the worm includes a rack surface, the worm meshes with the rack surface, and the micromotor is used to drive the worm to rotate, thereby driving the slider to move through the worm. This design is conducive to improving the integration of the feed network system, thereby facilitating the miniaturization of the feed network system.

[0023] In another possible implementation of the present application, the drive device includes a micromotor, the power mechanism includes a gear, and the slider includes a gear surface. The gear surface of the gear meshes with the gear surface of the slider. The micromotor is used to drive the gear to rotate, thereby causing the gear to drive the slider to move. In this implementation, providing a gear surface on the slider that meshes with the gear facilitates improving the compactness of the feed network system, thereby facilitating a reduction in the size of the feed network system.

[0024] In another possible implementation of the present application, the drive device includes a linear motor, the output end of which is connected to the sliding member. Since the structure of the drive device is relatively simple, it is conducive to reducing the volume of the power mechanism, thereby facilitating the reduction of the overall size of the feed network system.

[0025] In the present application, the feed network can be configured in a variety of ways. For example, in one possible implementation, the fixed member includes a metal strip line having a functional circuit, and the sliding member includes another functional circuit, wherein the other functional circuit of the sliding member is electrically coupled to the functional circuit of the metal strip line. With this design, the electrical parameters of the functional circuit of the fixed member can be changed by changing the coupling electrical connection between the functional circuits of the two members during the sliding movement of the sliding member relative to the fixed member.

[0026] In this implementation, the feed network can be a reconfigurable network, and the functional circuit of the metal strip line and the other functional circuit of the slider can be selected based on the function to be implemented by the feed network. For example, the functional circuit of the metal strip line may include at least one of a power divider, a bridge, a filter, and a transmission line. The other functional circuit of the slider may include at least one of a power divider, a bridge, a filter, and a transmission line.

[0027] In another possible implementation of the present application, the fixed member includes a metal strip line provided with a functional circuit, and the sliding member includes an insulating medium that covers a portion of the metal strip line. With this feed network design, as the sliding member slides relative to the fixed member, the portion of the metal strip line covered by the insulating medium changes, thereby causing a change in the dielectric constant of the entire environment surrounding the metal strip line, thereby altering the electrical performance of the metal strip line.

[0028] In this implementation, the feeding network can be a phase shifter. When the sliding part slides relative to the fixed part to change the dielectric constant of the environment in which the metal strip line is located, the electrical length of the antenna signal transmitted through the metal strip line can be changed, thereby realizing the phase shifter to adjust the phase of the antenna signal.

[0029] In another possible implementation of the present application, the fixed member includes a metal strip line having a functional circuit, and the sliding member includes a metal slider electrically coupled to the metal strip line. The feed network employs the aforementioned design, and as the slider slides relative to the fixed member, the coupling between the two can be altered, thereby changing the electrical parameters of the functional circuit of the fixed member.

[0030] In this implementation, the feeding network can also be a phase shifter, and the sliding part slides relative to the fixed part to change the electrical parameters of the functional circuit of the metal strip line, thereby changing the electrical length of the antenna signal transmitted through the metal strip line, so as to achieve the phase shifter to adjust the phase of the antenna signal.

[0031] The present application does not limit the specific arrangement of the feed network and the power mechanism. For example, in one possible implementation, the first housing is a hollow structure, and the first housing includes a hollow area, and the power mechanism can be installed in the hollow area. This can make the arrangement of the power mechanism and the feed network more compact, thereby facilitating the miniaturization of the feed network system.

[0032] In a second aspect, the present application further provides an antenna comprising a control system and at least two feed network systems as described in the first aspect. The control system is configured to control a drive device of each feed network system to drive a sliding member to slide relative to a fixed member. In the antenna provided in the present application, since the feed network and power mechanism of the feed network system adopt an integrated design, the feed network system can be installed and arranged as a whole in the antenna, which is beneficial for reducing the space occupied by the feed network system in the antenna and for improving the flexibility of the arrangement of the feed network system in the antenna, thereby reducing the complexity of the antenna design and thereby meeting the design requirements of miniaturization and lightweighting of the antenna.

[0033] In a third aspect, the present application further provides a base station comprising a radio frequency processing unit, a baseband processing unit, and the antenna of the second aspect, wherein the baseband processing unit is connected to the antenna via the radio frequency processing unit. Since the antenna provided in the present application is relatively small, a large number of antennas can be simultaneously deployed in the base station, which helps increase the types of signals that can be radiated by the base station, thereby expanding the scope of application of the base station.

[0034] In a fourth aspect, the present application further provides a communication system, the communication system comprising a terminal and the base station of the third aspect, wherein the terminal is in communication connection with the base station. The communication system provided by the present application has good communication performance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0063] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be understood as being limited to the embodiments set forth herein. The same figure marks in the figures represent the same or similar structures, and thus their repeated description will be omitted. The words expressing position and direction described in the embodiments of the present application are all explained with reference to the accompanying drawings as examples, but changes can be made as needed, and the changes made are all included in the scope of protection of the present application. The drawings in the embodiments of the present application are only used to illustrate the relative position relationship and do not represent the true proportion.

[0064] It should be noted that the following description sets forth specific details to facilitate understanding of the present application. However, the present application can be implemented in a variety of other ways than those described herein, and those skilled in the art may make similar generalizations without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0065] In order to facilitate the understanding of the feeding network system, antenna and base station provided in the present application, the application scenario is first introduced below. Figure 1 exemplarily shows a schematic diagram of a communication system architecture applicable to an embodiment of the present application. As shown in Figure 1, the communication system architecture may include a base station 1000 and a terminal 2000. Wireless communication can be achieved between the base station 1000 and the terminal 2000. The base station 1000 can also be called an access network device or an access node, which can be located in a base station subsystem (BBS), a terrestrial radio access network (UMTS terrestrial radio access network, UTRAN) or an evolved universal terrestrial radio access (E-UTRAN), and is used to provide signal cell coverage to achieve communication between the terminal device and the wireless network. Specifically, the base station 1000 can be a base transceiver station (BTS) in a global system for mobile communication (GSM) or a (code division multiple access, CDMA) system, a node B (NodeB, NB) in a wideband code division multiple access (WCDMA) system, an evolutionary node B (eNB or eNodeB) in a long term evolution (LTE) system, a transmission reception point (TRP), a next generation NodeB (gNB) in a 5G mobile communication system, a next generation base station in a sixth generation (6G) mobile communication system, an access network device or a module of an access network device in an open access network (ORAN) system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. The base station may be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU) as described below.Among them, in the ORAN system, CU can also be called O-CU, DU can also be called open (open, O)-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CUP-UP, and RU can also be called O-RU. The base station 1000 of the present application can be a macro base station, a micro base station or an indoor station, a relay node or a donor node, or it can also be a wireless controller in a cloud radio access network (CRAN) scenario. Or the base station 1000 can also be a server, a vehicle-mounted device, a wearable device, a g node (gNodeB or gNB) in a new radio (NR) system, an access network device in a future evolved network, etc. For example, the base station in the vehicle to everything (V2X) technology can be a road side unit (RSU). Multiple base stations 1000 in the communication system can be base stations of the same type or different types. The base station 1000 can communicate with the terminal 2000, or communicate with the terminal 2000 through a relay station. The terminal 2000 can communicate with multiple base stations 1000 in different access technologies.

[0066] Base station 1000 is equipped with an antenna 100 to transmit signals in space. Figure 2 shows a schematic diagram of an application scenario for antenna 100 equipped with base station 1000 shown in Figure 1. Figure 2 illustrates structures such as a support frame 200 and antenna 100. Antenna 100 includes a radome 10, which is secured to a support frame 200, such as a pole or tower, to facilitate signal reception or transmission. Radome 10 has excellent electrical properties for electromagnetic wave penetration and mechanical properties that can withstand the effects of harsh external environments, thereby protecting the antenna system from external environmental influences.

[0067] The base station 1000 may further include a radio frequency processing unit 300 and a baseband processing unit 400. The antenna 100 is connected to the radio frequency processing unit 300 via an antenna connector 20 located outside the antenna cover 10. The baseband processing unit 400 may be connected to the antenna 100 via the radio frequency processing unit 300. In some embodiments, the radio frequency processing unit 300 may also be referred to as a remote radio unit (RRU), and the baseband processing unit 400 may also be referred to as a baseband unit (BBU).

[0068] The support frame 200 is fixed to the ground at a certain height, and the antenna 100 is fixed to the support frame 200 to meet the radiation distance requirements of the antenna 100. The antenna 100 is removably fixed to the support frame 200 by adjusting the bracket 600, so that the antenna 100 can receive or transmit signals. The orientation of the antenna 100 can be adjusted in a direction perpendicular to the height of the support frame 200 by adjusting the bracket 600.

[0069] In one possible embodiment, as shown in FIG2 , the RF processing unit 300 may be integrated with the antenna 100, and the baseband processing unit 400 may be located at the distal end of the antenna 100. In this case, the RF processing unit 300 and the antenna 100 may be collectively referred to as an active antenna unit (AAU). It should be noted that FIG2 is only an example of the positional relationship between the RF processing unit 300 and the antenna 100. In other embodiments, the RF processing unit 300 and the baseband processing unit 400 may also be located at the distal end of the antenna 100. The RF processing unit 300 and the baseband processing unit 400 may be connected via a connecting wire 500.

[0070] A grounding device 700 is provided between the baseband processing unit 400 and the connecting wire 500. The grounding device 700 typically comprises a grounding electrode buried underground. A sealant may be provided at the connection between the antenna 100 and the connecting wire 500, and a sealant may also be provided at the connection between the grounding device 700 and the connecting wire 500. Specifically, the sealant may comprise at least one of insulating sealing tape and polyvinyl chloride (PVC) insulating tape. Of course, the sealant may also be of other structures and is not limited to tape.

[0071] Furthermore, FIG3 is a structural schematic diagram of the antenna 100 provided in an embodiment of the present application. As shown in FIG3 , the antenna 100 may include a radiation unit 30 and a reflector 40. The radiation unit 30 may also be referred to as an antenna vibrator, a vibrator, etc. The radiation unit 30 is a unit constituting the basic structure of the antenna array, which can effectively radiate or receive antenna signals. The frequencies of different radiation units 30 may be the same or different. The reflector 40 may also be referred to as a base plate, an antenna panel, or a metal reflective surface, etc. The reflector 40 may reflect the received signal and concentrate it at the receiving point. The radiation unit 30 is usually placed on one side of the reflector 40, which not only greatly enhances the signal reception or transmission capability, but also blocks and shields interference signals from the back of the reflector 40. In the present application, the back of the reflector 40 refers to the side of the reflector 40 opposite to the side for setting the radiation unit 30.

[0072] In antenna 100, a feed network system is provided between the radiating element 30 and the antenna connector 20. The feed network system can provide specific power and phase to the radiating element 30. The feed network system typically includes an adjustment unit 50 and a feed network. As shown in Figure 3, the feed network includes a phase shifter 60. The adjustment unit 50 is used to achieve different radiation beam directions, and the phase shifter 60 is used to change the maximum direction of signal radiation. By adjusting the corresponding radiating element 30 through the phase shifter 60, the electrical downtilt angle of the signal radiated by each radiating element 30 can be changed, thereby changing the radiation direction of each radiating element 30 to meet signal coverage requirements.

[0073] As shown in Figure 3, a functional module 70 can also be provided between the phase shifter 60 and the antenna connector 20. The functional module 70 can expand the performance of the antenna 100. Exemplarily, the functional module 70 can include one or a combination of at least two of a combiner, a power splitter, a filter, and a microwave circuit. A combiner or power splitter can be used in either forward or reverse directions to split one signal into multiple signals or combine multiple signals into one. A filter can be used to filter out interference signals. In some cases, the phase shifter 60 also functions as a power splitter or combiner, eliminating the need for a power splitter or combiner in the feed network system. The different components included in the feed network system can be connected via transmission lines and connectors. It should be noted that the power splitter or combiner can be located inside or outside the radome 10, and the connection relationships between the various components mentioned above are not unique. Figure 3 only illustrates one possible positional relationship and connection method for the various components.

[0074] 3 , the adjustment unit 50 may include a power mechanism 5a and a calibration network 5b. The power mechanism 5a may drive the phase shifter 60 to change the direction of different radiation beams of the antenna 100. The calibration network 5b may send a calibration signal to the power mechanism 5a to control its operation.

[0075] Taking the phase shifter 60 as an example, the principle by which the power mechanism 5a drives the phase shifter 60 to change the directionality of the different radiation beams of the antenna 100 is as follows: the power mechanism 5a drives the insulating medium of the phase shifter 60 to move relative to the metal strip line, thereby changing the relative position of the insulating medium and the metal strip line. Because the environment surrounding the metal strip line of the phase shifter 60 has a certain dielectric constant, the dielectric constant of the environment surrounding the metal strip line changes when the relative position of the insulating medium and the metal strip line changes. Since the metal strip line is electrically connected to the radiating element 30 of the antenna 100, changing the dielectric constant of the environment surrounding the metal strip line can adjust the phase of the antenna signal transmitted through the metal strip line, thereby adjusting the directivity of the signal radiation direction of the antenna 100.

[0076] In current antennas, the phase shifter and power mechanism are typically designed as two independently constructed components, meaning they are designed separately and then installed and laid out separately within the antenna. Furthermore, the power mechanism of the feed network system in current antennas typically utilizes a rotating motor, a rack and pinion, and a drive rod. The drive rod is connected to the rack and pinion and the insulating medium of the phase shifter. This allows the rotating motor to drive the gear, which in turn drives the rack in linear motion. The drive rod, driven by the rack, then drives the insulating medium in linear motion relative to the metal wire. Because the rotating motor itself is relatively large, and its rotational motion must be transmitted to the drive rod via the rack and pinion before being transferred to the insulating medium, the intermediate transmission mechanisms between the rotating motor and the insulating medium are numerous. This results in a larger and heavier power mechanism, and its cost is high. Consequently, the feed network system occupies a larger space within the antenna, failing to meet current development requirements for antenna miniaturization and lightweighting.

[0077] In view of this, the feed network system provided in this application integrates the power mechanism and the feed network so that the power mechanism and the feed network can be installed and arranged as a whole in the antenna. This helps to reduce the space occupied by the feed network system in the antenna, thereby helping to meet the requirements of the antenna's miniaturization design. To facilitate understanding of the technical solution of this application, the feed network system provided in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0078] In this application, integrated design means that multiple structures are connected directly or indirectly so as to be moved or installed as a whole. This is conducive to improving the compactness of the multiple structures adopting integrated design, and can achieve the effect of structural simplification by sharing some structures, thereby helping to reduce the space occupied by the multiple structures.

[0079] Referring to Figure 4, Figure 4 is a structural schematic diagram of a feed network system provided in an embodiment of the present application. The feed network system includes a feed network 6 and a power mechanism 5a, wherein the feed network 6 includes a first shell 601. The first shell 601 can serve as a supporting structure for the feed network 6 to ensure the structural reliability of the entire feed network 6. In addition, when the first shell 601 can form a closed cavity, the first shell 601 can also provide signal shielding and protection for other structures of the feed network 6; and when the feed network 6 does not require signal shielding, the first shell 601 can also be a frame structure to reduce the weight of the feed network 6.

[0080] In addition, in the feed network system shown in FIG4 , the power mechanism 5a includes a second housing 501, and the first housing 601 is fixedly connected to the second housing 501, so that the feed network 6 and the power mechanism 5a are integrated into a whole. This facilitates the miniaturization of the feed network system and improves the layout flexibility of the feed network system.

[0081] It is worth mentioning that the present application does not limit the specific connection method between the first shell 601 and the second shell 501. For example, the first shell 601 and the second shell 501 can be detachably connected by a threaded connection, which is conducive to improving the maintenance convenience of the feeding network 6 and the power mechanism 5a. In addition, the first shell 601 and the second shell 501 can also be fixedly connected by welding, riveting or bonding to improve the reliability of the connection between the two. In addition, the first shell 601 and the second shell 501 can be directly connected, or they can be indirectly connected through an intermediate transition structure, as long as the power mechanism 5a and the feeding network 6 can be connected and integrated into a whole. In some possible embodiments, the first shell 601 and the second shell 501 can also be an integrally molded structure, which can make the structure of the feeding network system more compact, so as to facilitate the reduction of the volume of the feeding network system.

[0082] Referring to Figure 5 , Figure 5 is an exploded view of the feed network system shown in Figure 4 . In this embodiment of the present application, the first housing 601 includes a first surface 6011, which is used to connect to the second housing 501. The first surface 6011 is the end surface of the first housing 601 facing the second housing 501. The first surface 6011 is a hollow surface to facilitate the connection between the components of the feed network 6 and the components of the power mechanism 5a. Alternatively, the other surfaces of the first housing 601 may be closed surfaces, so that the first housing 601 can provide protection for other components of the feed network 6.

[0083] In addition, in the feed network system shown in Figure 5, the second shell 501 includes a second surface 5011, which is the end surface of the second shell 501 facing the first shell 601. The second surface 5011 can be a hollow surface to facilitate the connection of the components in the power mechanism 5a with the components in the feed network 6. In addition, the other surfaces of the second shell 501 can all be closed surfaces, so that the second shell 501 can protect the other components in the power mechanism 5a and reduce the leakage of magnetic signals that may be generated in the power mechanism 5a, which is conducive to reducing the interference of the power mechanism 5a with the antenna radiation signal. Alternatively, in other possible embodiments of the present application, for example, when whether or not magnetic components are provided in the feed network 6 does not interfere with the antenna radiation signal, all surfaces of the second shell 501 can be hollow surfaces. In this case, the second shell 501 can be understood as a frame structure, which is conducive to reducing the weight of the power mechanism 5a, thereby reducing the weight of the feed network system as a whole, so as to improve the convenience of transportation and installation of the feed network system.

[0084] In an embodiment of the present application, in order to facilitate the connection between the components in the feed network 6 and the components in the power mechanism 5a, in addition to setting the first surface 6011 of the first shell 601 and the second surface 5011 of the second shell 501 as hollow surfaces, it is also possible to set only a first slot (not shown in FIG5 ) on the first surface 6011 of the first shell 601, and the other parts of the first surface 6011 except the first slot can be closed surfaces. In addition, the second surface 5011 of the second shell 501 is provided with a second slot (not shown in FIG5 ), and the other parts of the second surface 5011 except the second slot are closed surfaces. Among them, the first slot and the second slot are arranged relative to each other, so that the components in the feed network 6 and the components in the power mechanism 5a can be connected through the first slot and the second slot. It is understandable that the shape and size of the first slot and the second slot can be specifically set according to the design requirements of the components connected between the feed network 6 and the power mechanism 5a, and are not limited in this application.

[0085] It is understandable that FIG4 shows a schematic diagram of an arrangement of the feed network 6 and the power mechanism 5a, wherein the first surface 6011 is a larger end surface of the first shell 601 of the feed network 6. When the feed network system is used in a specific application, the arrangement of the feed network 6 and the power mechanism 5a can also be adaptively adjusted according to the layout space of the specific application scenario or the specific structure of the feed network 6 and the power mechanism 5a. For example, in the feed network system shown in FIG6, the power mechanism 5a is connected to the smaller end surface of the first shell 601 of the feed network 6. For example, in the feed network system shown in FIG7, the power mechanism 5a is arranged on another larger end surface of the feed network 6. For example, in the feed network system shown in FIG8, the first shell 601 of the feed network 6 is a hollow structure, and the first shell 601 includes a hollow area 6012. The power mechanism 5a can be installed in the hollow area 6012 of the first shell 601, which can make the overall structure formed by the assembly of the feed network 6 and the power mechanism 5a more compact. The above are just a few exemplary descriptions of the arrangement of the feed network 6 and the power mechanism 5a. On this basis, the arrangement of the two can also be adaptively modified. They will not be introduced one by one here, but they should all be understood to fall within the scope of protection of this application.

[0086] Referring to Figure 9, which is a cross-sectional view taken along line AA of the feed network system shown in Figure 4, the feed network 6 further includes a fixing member 602 and a sliding member 603. The fixing member 602 and the sliding member 603 are mounted on the first housing 601. The fixing member 602 is connected to the first housing 601 by, but not limited to, snap-fit ​​connection, riveting, bonding, or threaded connection. Furthermore, the fixing member 602 and the first housing 601 may be connected directly or indirectly via an intermediate connection structure, as long as the relative movement between the fixing member 602 and the first housing 601 is restricted.

[0087] 9 , the power mechanism 5a further includes a driving device 502, which can be mounted on the second housing 501. In the present application, the fixing member 602, the sliding member 603 and the driving device 502 are integrated, which helps to reduce the volume and weight of the feed network system.

[0088] The driving device 502 can be used to drive the sliding member 603 to slide relative to the fixed member 602. It is understood that, based on the design requirements of a specific application scenario, the driving device 502 can be specifically configured so that the driving device 502 can drive the sliding member 603 to slide relative to the fixed member 602. The sliding trajectory of the sliding member 603 relative to the fixed member 602 can be a straight line or a predetermined curve, which is not specifically limited in this application.

[0089] Furthermore, as can be understood from the above description of the first housing 601 of the feed network 6 and the second housing 501 of the power mechanism 5a, when the first surface 6011 of the first housing 601 and the second surface 5011 of the second housing 501 are hollowed-out surfaces, the drive device 502 can be connected to the slider 603 via the hollowed-out areas of the first surface 6011 and the second surface 5011. Furthermore, when the first surface 6011 of the first housing 601 is provided with a first slot and the second surface 5011 of the second housing 501 is provided with a second slot, the drive device 502 can be connected to the slider 603 via the first slot and the second slot. In this case, the specific arrangement of the first slot and the second slot must also take into account the sliding trajectory of the slider 603 to avoid interference with the movement of the slider 603.

[0090] It is worth mentioning that in the embodiment of the present application, in order to facilitate the connection between the driving device 502 and the sliding member 603, part of the sliding member 603 can be located in the second shell 501, and the driving device 502 can be connected to the part of the sliding member 603 located in the second shell 501.

[0091] In addition, in some possible embodiments of the present application, the power mechanism may not be provided with a second shell 501, which can also be understood as the feeding network 6 and the power mechanism 5a sharing the first shell 601, which is conducive to simplifying the structure of the feeding network system and is conducive to realizing a miniaturized and lightweight design of the feeding network system.

[0092] To facilitate understanding of the feed network system provided in the present application, as shown in FIG9 , the specific configuration of the feed network system will be described below using the feed network 6 as a dielectric phase shifter as an example. In the dielectric phase shifter, the fixing member 602 includes a metal strip line 6021, which may be, but is not limited to, a sheet metal strip line, and its material may be, but is not limited to, copper. Furthermore, the fixing member 602 may also include a support frame (not shown in FIG9 ) made of an insulating material, which may be connected to the first housing 601 and the metal strip line 6021 to support the metal strip line 6021; or the fixing member 602 includes a printed circuit board, and the metal strip line 6021 is a metal trace in the printed circuit board. Furthermore, the sliding member 603 in the dielectric phase shifter includes an insulating medium.

[0093] As can be seen from the above description of the dielectric phase shifter, the metal strip line 6021 can be used to connect to the antenna's radiating element to achieve directional adjustment of the antenna signal's radiation direction by the dielectric phase shifter. Based on this, it can be understood that the metal strip line 6021 can be provided with a functional circuit for adjusting the phase of the antenna signal. The insulating dielectric of the slider 603 covers a portion of the metal strip line 6021. This allows the metal strip line 6021 to be partially covered by the insulating dielectric, while another portion of the metal strip line 6021 is not covered by the insulating dielectric. Consequently, the dielectric constants of the environments surrounding each portion of the metal strip line 6021 differ. In this way, in the process of the power mechanism 5a driving the sliding part 603 to slide relative to the fixed part 602, the part of the metal strip line 6021 covered by the insulating medium changes, thereby causing the dielectric constant of the environment in which the entire metal strip line 6021 is located to change, so that the electrical performance of the metal strip line 6021 changes, which can change the electrical length of the antenna signal transmitted through the metal strip line 6021, thereby realizing the phase adjustment of the antenna signal by the dielectric phase shifter.

[0094] In the present application, the driving device 502 and the sliding member 603 can be directly connected, that is, the driving device 502 and the sliding member 603 can be directly contacted and transmission-connected, so that the force output by the driving device 502 can be directly transmitted to the sliding member 603, which is beneficial to improving the transmission efficiency of the force between the driving device 502 and the sliding member 603, and is beneficial to reducing the volume of the feeding network system.

[0095] When specifically setting up the driving device 502, reference may be made to FIG9 . In this embodiment of the present application, the driving device 502 may be a piezoelectric driving device, and when specifically setting up the driving device 502, reference may be made to FIG10 , which is a schematic structural diagram of the driving device 502 provided in an embodiment of the present application. The driving device 502 includes a device fixing frame 5021 and a resonance component 5022. The device fixing frame 5021 is fixedly connected to the first shell 601, or the device fixing frame 5021 is fixedly connected to the second shell 501, or the device fixing frame 5021 is part of the second shell 501. In this embodiment of the present application, the device fixing frame 5021 may serve as a supporting component for the entire driving device 502 to support other structures of the driving device 502.

[0096] 9 and 10 , the resonant component 5022 is located on a side of the device holder 5021 facing away from the first housing 601. In this application, for ease of description, the arrangement direction of the resonant component 5022 and the device holder 5021 is defined as the Y direction.

[0097] Referring to Figure 11 , Figure 11 is a schematic diagram of the structure of the resonant component 5022 of the driving device 502 shown in Figure 10 . The resonant component 5022 includes a metal elastic body 50221 and a piezoelectric material layer 50222. The metal elastic body 50221 can be made of a deformable metal material such as stainless steel or phosphor bronze, and the piezoelectric material layer 50222 can include multiple stacked piezoelectric ceramic layers. The piezoelectric material layer 50222 is disposed on at least one surface of the metal elastic body 50221 and can be connected to the surface of the metal elastic body 50221 by bonding or other means.

[0098] In the embodiment of the present application, the number of piezoelectric material layers 50222 in the resonant component 5022 is not limited and can be selected according to specific needs. For example, in the resonant component 5022 shown in FIG11 , it includes two piezoelectric material layers 50222. The two piezoelectric material layers 50222 are disposed on the first surface 502211 of the metal elastic body 50221, wherein the first surface 502211 of the metal elastic body 50221 faces away from the device fixing frame 5021. In addition, in the resonant component 5022 shown in FIG11 , the two piezoelectric material layers 50222 are arranged adjacent to each other. In the embodiment of the present application, for ease of description, the arrangement direction of the two piezoelectric material layers 50222 in the resonant component 5022 shown in FIG11 can be defined as the X direction.

[0099] Referring to Figure 12, Figure 12 is a schematic structural diagram of the resonant assembly 5022 shown in Figure 11 from another angle. The metal elastic body 50221 further includes a driving foot 502213, which is disposed on the second surface 502212 of the metal elastic body 50221. The driving foot 502213 protrudes from the second surface 502212 along the direction from the first surface 502211 to the second surface 502212, wherein the second surface 502212 of the metal elastic body 50221 is disposed opposite to the first surface 502211. This application does not limit the number of driving feet 502213 of the metal elastic body 50221. For example, in the resonant assembly 5022 shown in Figure 12, the metal elastic body 50221 has two driving feet 502213. Alternatively, in other possible embodiments, the metal elastic body 50221 may have one, three, four, or more driving feet 502213.

[0100] In the present application, the metal elastomer 50221 can be an integrally molded structure, that is, the driving foot 502213 is a part of the metal elastomer 50221, the two are made of the same material, and they are processed through a single processing process to simplify the structure of the metal elastomer 50221 and improve production efficiency; or the driving foot 502213 can be an independent structure, which can be fixed to the second surface 502212 of the metal elastomer 50221 by welding or bonding. At this time, the materials of the driving foot 502213 and the metal elastomer 50221 can be the same or different, which is conducive to improving the setting flexibility of the driving foot 502213.

[0101] Continuing with FIG11 , the resonant assembly 5022 further includes a power supply module 50223, which is electrically connected to each piezoelectric material layer 50222, so that the power supply module 50223 can be used to apply a voltage to each piezoelectric material layer 50222. Thus, when the high-frequency voltages applied by the power supply module 50223 to the two piezoelectric material layers 50222 disposed on the first surface 502211 of the metal elastic body 50221 have a certain phase difference, the metal elastic body 50221 can be driven to deform in a predetermined pattern, for example, to perform a microscopic elliptical motion, thereby driving the driving foot 502213 to move synchronously.

[0102] The driving device 502 shown in FIG10 further includes a resonance component bracket 5023 and a resonance component fixing frame 5024, wherein the metal elastic body 50221 of the resonance component 5022 is connected to the resonance component bracket 5023, and the connection method thereof can be, but is not limited to, threaded connection, welding, or riveting.

[0103] The resonant component fixing frame 5024 is located between the device fixing frame 5021 and the resonant component bracket 5023, and is fixedly connected to the device fixing frame 5021. The resonant component fixing frame 5024 includes a mounting groove 50241 that extends through the resonant component fixing frame 5024 along the alignment direction of the resonant component fixing frame 5024 and the device fixing frame 5021.

[0104] The resonant assembly bracket 5023 is mounted in the mounting slot 50241 of the resonant assembly fixing frame 5024, and the resonant assembly bracket 5023 overlaps the side of the resonant assembly fixing frame 5024 facing away from the device fixing frame 5021. It is worth noting that in the present application, there is no connection between the resonant assembly bracket 5023 and the resonant assembly fixing frame 5024. Therefore, when the metal elastic body 50221 of the resonant assembly 5022 performs microscopic elliptical motion according to a predetermined pattern, the resonant assembly bracket 5023 can be driven to move synchronously with the metal elastic body 50221.

[0105] 10 , along the X direction, the mounting groove 50241 includes a first groove wall 502411 and a second groove wall 502412 opposite to each other, and a lateral pre-compression assembly 5025 is provided between the resonant assembly bracket 5023 and at least one of the first groove wall 502411 and the second groove wall 502412 .

[0106] In the present application, the lateral preload assembly 5025 includes a lateral preload elastic member 50251 and a first rolling member 50252. The lateral preload elastic member 50251 may be, but is not limited to, an elastic structural member such as a leaf spring, a wave spring, a compression spring, or a tension spring. For example, in the case where the lateral preload assembly 5025 is disposed between the resonant assembly bracket 5023 and the first groove wall 502411, one end of the lateral preload elastic member 50251 abuts the first groove wall 502411, and the other end of the lateral preload elastic member 50251 abuts the first rolling member 50252. As a result, the elastic force of the lateral preload elastic member 50251 presses the first rolling member 50252 toward the end of the resonant assembly bracket 5023 facing the first groove wall 502411. This allows the lateral preload assembly 5025 to limit the movement of the resonant assembly bracket 5023 along the alignment direction of the first groove wall 502411 and the second groove wall 502412 during its movement with the metal elastic body 50221, thereby preventing the resonant assembly bracket 5023 from moving in this direction. Furthermore, because the end surface of the resonant assembly bracket 5023 facing the first groove wall 502411 abuts the first rolling element 50252, the provision of the lateral preload assembly 5025 does not affect the movement of the resonant assembly bracket 5023 with the metal elastic body 50221. Therefore, by providing the lateral preload assembly 5025 between the resonant assembly bracket 5023 and the first groove wall 502411, the stability of the movement of the resonant assembly bracket 5023 can be effectively improved, thereby improving the stability of the movement of the resonant assembly 5022, which in turn improves the stability of the driving force output by the resonant assembly 5022 via the driving foot 502213.

[0107] It is understood that in order to ensure stable contact between the first rolling element 50252 and the end of the resonant assembly bracket 5023, a groove may be provided at the end of the resonant assembly bracket 5023 facing the first groove wall 502411. At least a portion of the first rolling element 50252 may be accommodated in the groove, and the sidewalls of the first rolling element 50252 may fit into contact with the groove walls, allowing the first rolling element 50252 to roll relative to the groove.

[0108] In the embodiment of the present application, the first rolling element 50252 can be, for example, a roller. Furthermore, a lateral pre-load assembly 5025 can be provided between the resonant assembly support 5023 and the second groove wall 502412, or it can be omitted. When a lateral pre-load assembly 5025 is provided between the resonant assembly support 5023 and the second groove wall 502412, its specific configuration can be described in the aforementioned embodiment and will not be further described here. Alternatively, only one first rolling element 50252 can be provided between the resonant assembly support 5023 and the second groove wall 502412, thereby improving the stability of the resonant assembly support 5023 while simplifying the structure of the piezoelectric drive device.

[0109] The power mechanism provided in this application also includes a follower 5026, which is used to connect to the sliding member 603. The follower 5026 can be located between the driving foot 502213 and the sliding member 603. In this application, the driving force output by the resonant assembly 5022 through the driving foot 502213 can act on the follower 5026, thereby driving the follower 5026 to move in a straight line. In a specific implementation, referring to Figure 10, along the Y direction, the follower 5026 is located between the device fixing frame 5021 and the resonant assembly 5022. The surface of the follower 5026 facing the resonant assembly 5022 abuts the driving foot 502213 of the resonant assembly 5022, so that the follower 5026 moves with the driving foot 502213 due to the friction between the follower 5026 and the driving foot 502213.

[0110] Since the friction force between the follower 5026 and the driving foot 502213 is the key to ensuring the movement stability of the follower 5026, in order to increase the friction force between the follower 5026 and the driving foot 502213, the piezoelectric driving device provided in this application also includes a friction member 5027. In the driving device 502 shown in Figure 10, the friction member 5027 is arranged on the surface of the follower 5026 facing the resonant component 5022, and the driving foot 502213 of the resonant component 5022 can abut against the friction plate 50271.

[0111] In the present application, the friction member 5027 can be a metal sheet, and the friction member 5027 is fixedly connected to the surface of the follower 5026 facing the resonant assembly 5022. The connection method can be, but is not limited to, welding, bonding, or clamping. Alternatively, the friction member 5027 and the follower 5026 are integrally formed. In this case, the friction member 5027 can be a portion of the surface of the follower 5026 facing the resonant assembly 5022 that has a higher friction coefficient formed by a grinding process.

[0112] In addition, to ensure that the driving foot 502213 of the resonant assembly 5022 abuts the driven member 5026, the driving device provided in the embodiment of the present application further includes a positive preload assembly 5028. The positive preload assembly 5028 is located on a side of the resonant assembly 5022 facing away from the device fixing frame 5021. The positive preload assembly 5028, under the action of an elastic force, presses the resonant assembly 5022 toward the driven member 5026. In a specific implementation, as shown in FIG10 , the positive preload assembly 5028 may include a positive preload elastic member 50281 and a pressure plate 50282. The positive preload elastic member 50281 may be located on a side of the pressure plate 50282 facing away from the resonant assembly 5022, so that the positive preload elastic member 50281, under the action of an elastic force, presses the pressure plate 50282 toward the resonant assembly 5022, thereby pressing the resonant assembly 5022 toward the driven member 5026. In the present application, the positive preload elastic member 50281 can be, but is not limited to, an elastic structural member such as a leaf spring, a wave spring, a compression spring, or a tension spring.

[0113] In the driving device 502 shown in Figure 10, a receiving groove 502821 can also be provided on the side of the pressure plate 50282 facing the positive prestressing elastic member 50281, and a portion of the positive prestressing elastic member 50281 can be accommodated in the receiving groove 502821 of the pressure plate 50282 to improve the structural reliability of the positive prestressing component 5028.

[0114] It is worth mentioning that in the driving device 502 shown in FIG10 , since the piezoelectric material layer 50222 is located on the side of the metal elastic body 50221 facing the positive preloading component 5028, to prevent the positive preloading component 5028 from damaging the piezoelectric material layer 50222, the piezoelectric driving device may further include a buffer pad 5029. The buffer pad 5029 is located between the positive preloading component 5028 and the resonant component 5022, and the positive preloading component 5028 presses the buffer pad 5029 toward the resonant component 5022 under the action of an elastic force. This application does not limit the material of the buffer pad 5029, and it can be exemplarily a flexible material layer such as foam.

[0115] Continuing with FIG. 10 , the piezoelectric drive device further includes a cover plate 50210. A positive preload assembly 5028 is positioned between the cover plate 50210 and the resonant assembly 5022. The cover plate 50210 is fixedly connected to the resonant assembly fixing frame 5024. The connection method may be, but is not limited to, a threaded connection, so that the cover plate 50210 and the resonant assembly fixing frame 5024 are detachably connected, facilitating maintenance or replacement of the resonant assembly 5022. In some possible embodiments, the cover plate 50210 and the resonant assembly fixing frame 5024 may also be fixedly connected by welding, bonding, or riveting to improve the connection reliability between the cover plate 50210 and the resonant assembly fixing frame 5024.

[0116] In addition, it can be understood that the positive prestressing elastic member 50281 of the positive prestressing assembly 5028 is located between the cover plate 50210 and the pressure plate 50282, and the positive prestressing elastic member 50281 can abut against the cover plate 50210 and the pressure plate 50282, and the pressure plate 50282 abuts against the resonance component 5022. In this way, the positive prestressing assembly 5028 can be pressed toward the resonance component 5022 through the connection between the cover plate 50210 and the resonance component fixing frame 5024, so that the positive prestressing assembly 5028 applies positive pressure along the normal direction to the resonance component 5022, so that the positive prestressing assembly 5028 presses the driving foot 502213 of the resonance component 5022 toward the follower 5026.

[0117] As described above, the follower 5026 can move linearly relative to the device mounting frame 5021 under the influence of the resonant assembly 5022. To enhance the stability of the follower 5026's movement, the device mounting frame 5021 includes a guide groove 50211, as shown in FIG10 . It will be appreciated that the guide groove 50211 is a linear guide groove extending along the X-direction. Furthermore, the follower 5026 can further include a slider (not shown in FIG10 ), which can be located on a side of the follower 5026 facing away from the resonant assembly 5022. The slider can be inserted into the guide groove 50211, and then, driven by the resonant assembly 5022, the slider of the follower 5026 can slide along the guide groove 50211.

[0118] To improve the smoothness of the movement of the follower 5026 relative to the device mounting frame 5021, the driving device 502 provided in this embodiment of the present application further includes a second rolling member 502110. The second rolling member 502110 is located between the follower 5026 and the device mounting frame 5021, and both the follower 5026 and the device mounting frame 5021 abut against the surface of the second rolling member 502110. Thus, during the movement of the follower 5026 relative to the device mounting frame 5021, the friction pair between the follower 5026 and the device mounting frame 5021 is a rolling friction pair, which can reduce the resistance to the relative movement between the follower 5026 and the device mounting frame 5021, thereby facilitating reduced power consumption of the driving device 502.

[0119] The specific type of the second rolling element 502110 is not limited in this application; exemplary embodiments include rollers or balls. It is understood that to improve the movement reliability of the second rolling element 502110, at least one of the device mounting frame 5021 and the follower 5026 may further include a limiting groove 50212. For example, in FIG10 , the device mounting frame 5021 includes a limiting groove 50212, and at least a portion of the second rolling element 502110 is accommodated within the limiting groove 50212. In this embodiment of the present application, both the device mounting frame 5021 and the follower 5026 may include limiting grooves 50212, with the limiting grooves 50212 disposed opposite each other. In this manner, a portion of the second rolling element 502110 is located within the limiting groove 50212 of the device mounting frame 5021, and a portion of the second rolling element 502110 is located within the limiting groove 50212 of the follower 5026.

[0120] The present application does not limit the number of second rolling elements 502110; illustratively, the number may be two, three, or more, and the number may be specifically determined based on the spacing between the device mounting bracket 5021 and the follower 5026. Furthermore, the present application does not limit the shape of the retaining groove 50212; illustratively, the retaining groove 50212 of the device mounting bracket 5021 may have a V-shaped or U-shaped cross-section, and the retaining groove 50212 of the follower 5026 may have a V-shaped or U-shaped cross-section, thereby preventing the second rolling element 502110 from falling out from between the device mounting bracket 5021 and the follower 5026.

[0121] In the present application, to facilitate the connection between the follower 5026 and the sliding member 603, refer to FIG13, which is an enlarged view of the partial structure at B in FIG10. The end of the follower 5026 facing the sliding member 603 includes a protrusion 50262, and the end of the sliding member 603 facing the follower 5026 includes a groove 6031. Alternatively, in some possible embodiments, the end of the sliding member 603 facing the follower 5026 may include a protrusion, and the end of the follower 5026 facing the sliding member 603 may include a groove. In this way, the follower 5026 and the sliding member 603 can be connected by a snap-fitting manner by inserting the protrusion into the groove.

[0122] In addition, referring to Figure 14 , Figure 14 is a schematic diagram of another connection method between the follower 5026 and the sliding member 603 provided in an embodiment of the present application. The end of the follower 5026 facing the sliding member includes a gear 50263, and the end of the sliding member 603 facing the follower 5026 includes a rack surface 6032. The gear surface of the gear 50263 meshes with the rack surface 6032. Thus, the follower 5026 and the sliding member 603 are connected in a transmission manner through the meshing of the gear surface and the rack surface 6032.

[0123] Based on the above introduction to the connection method between the follower 5026 and the sliding member 603, the connection method between the two can also be adaptively modified. For example, the follower 5026 and the sliding member 603 can also be provided with hooks, and the two can be connected by the hooks, or the two can be connected by welding, riveting or threaded connection. They are not listed one by one here, but they should all be understood to fall within the scope of protection of this application.

[0124] The power mechanism 5a provided in the above-described embodiment of the present application utilizes piezoelectric drive to directly output linear driving force by bringing the driving foot 502213 of the metal elastic body 50221 of the resonant assembly 5022 into frictional contact with the follower 5026, thereby converting the microscopic motion of the resonant assembly 5022 into macroscopic linear motion of the follower 5026. This eliminates the need for an intermediate transmission mechanism, resulting in a simpler, smaller, and lighter power mechanism. This facilitates miniaturization and lightweight design of a feed network system when the power mechanism 5a is applied. Furthermore, since the power mechanism 5a lacks magnetic components, interference with antenna signals when the feed network system including the power mechanism 5a is used, thereby improving the antenna's signal radiation performance.

[0125] Based on the above-mentioned embodiment's introduction to the driving principle of the driving device 502 provided in the present application, a series of variations can also be made to the specific structure of the driving device 502. For example, refer to FIG15 , which is another structural schematic diagram of the driving device 502 provided in the embodiment of the present application. The driving device 502 shown in FIG15 is slightly different from the above-mentioned embodiment. Specifically, in the driving device 502 shown in FIG15 , the resonant component 5022 includes four piezoelectric material layers 50222, two of the four piezoelectric material layers 50222 are arranged on the first surface 502211 of the metal elastomer 50221, and the other two of the four piezoelectric material layers 50222 are arranged on the second surface 502212 of the metal elastomer 50221. FIG15 only shows the two piezoelectric material layers 50222 arranged on the first surface 502211 of the metal elastomer 50221. In this embodiment of the present application, the arrangement direction of the two piezoelectric material layers 50222 arranged on the first surface 502211 of the metal elastic body 50221 is the same as the arrangement direction of the two piezoelectric material layers 50222 arranged on the second surface 502212 of the metal elastic body 50221, and they are both arranged along the X direction.

[0126] In addition, referring to Figure 16, Figure 16 is an exploded view of the driving device 502 shown in Figure 15. The metal elastic body 50221 includes a hollow area 502214. Two piezoelectric material layers 50222 disposed on the first surface 502211 of the metal elastic body 50221 are respectively located on either side of the hollow area 502214. Furthermore, two piezoelectric material layers 50222 disposed on the second surface 502212 of the metal elastic body 50221 are respectively located on either side of the hollow area 502214.

[0127] In a possible embodiment of the present application, the two piezoelectric material layers 50222 arranged on the first surface 502211 of the metal elastomer 50221 and the two piezoelectric material layers 50222 arranged on the second surface 502212 of the metal elastomer 50221 can be arranged in a one-to-one correspondence, so that the two piezoelectric material layers 50222 arranged on the first surface 502211 of the metal elastomer 50221 and the two piezoelectric material layers 50222 arranged on the second surface 502212 of the metal elastomer 50221 are symmetrically arranged relative to the metal elastomer 50221, which is conducive to the miniaturized design of the resonant component 5022, thereby facilitating the reduction of the volume of the driving device 502.

[0128] Continuing with FIG16 , the metal elastic body 50221 includes two actuating feet 502213, which are located on either side of the aforementioned hollow region 502214. The arrangement of the two actuating feet 502213 intersects with the arrangement of the two piezoelectric material layers 50222 disposed on the same surface of the metal elastic body 50221. For example, the arrangement of the two actuating feet 502213 is perpendicular to the arrangement of the two piezoelectric material layers 50222 disposed on the same surface of the metal elastic body 50221. Furthermore, each actuating foot 502213 protrudes from a corresponding side surface of the metal elastic body 50221 in a direction away from the hollow region 502214.

[0129] As shown in FIG16 , the friction member 5027 is located on the side of the driven member 5026 facing the resonant assembly 5022. The friction member 5027 is connected to the surface of the driven member 5026 facing the resonant assembly 5022. The connection method may be, but is not limited to, welding, bonding, or clamping. Furthermore, the friction member 5027 includes two opposing friction plates 50271 (see also FIG15 and FIG16 ). The metal elastic body 50221 is located between the two friction plates 50271, and the two driving feet 502213 abut against the two friction plates 50271 in a one-to-one correspondence. In the driving device 502 shown in Figure 16 of the present application, the surface of the follower 5026 facing the resonant component 5022 may also include a fixing frame 50264, which protrudes from the surface of the follower 5026 along the direction from the follower 5026 to the resonant component 5022. The two friction plates 50271 can be connected to the fixing frame 50264, which can improve the convenience and reliability of the connection between the friction plates 50271 and the follower 5026.

[0130] Continuing with Figures 15 and 16 , the positive preload assembly 5028 is connected to the surface of the follower 5026 facing the resonant assembly 5022 by, but not limited to, welding, bonding, or clamping. The positive preload assembly 5028 abuts against the surface of each friction plate 50271 facing away from the metal elastic body 50221 , and can apply a normal positive pressure to each friction plate 50271 , such that, under the action of the elastic force, the positive preload assembly 5028 presses each friction plate 50271 toward the corresponding driving foot 502213 .

[0131] It is worth mentioning that in the driving device 502 shown in Figure 16 of the present application, the positive pre-load assembly 5028 may include a claw-shaped spring, at least one elastic claw portion of the claw-shaped spring abuts against the surface of a friction plate 50271 facing away from the metal elastomer 50221, and at least one elastic claw portion of the claw-shaped spring abuts against the surface of another friction plate 50271 facing away from the metal elastomer 50221, so as to apply positive pressure in the normal direction to each friction plate 50271, thereby pressing each friction plate 50271 toward the corresponding driving foot 502213. Furthermore, to increase the friction between the friction plate 50271 and the driving foot 502213, the squeezing force applied by the positive preload assembly 5028 to the friction plate 50271 can be increased. Specifically, the positive preload assembly 5028 can include two or more claw-shaped springs, with at least one elastic claw portion of each claw-shaped spring abutting against the surface of one friction plate 50271 facing away from the metal elastic body 50221, and at least one elastic claw portion of each claw-shaped spring abutting against the surface of another friction plate 50271 facing away from the metal elastic body 50221. Furthermore, the two or more claw-shaped springs of the positive preload assembly 5028 can be detachably connected to enhance the flexibility of the positive preload assembly 5028.

[0132] The other structures of the driving device 502 shown in FIG. 15 and FIG. 16 may be configured with reference to any of the above embodiments, and will not be described in detail here.

[0133] In the driving device 502 shown in Figures 15 and 16 , the power supply module 50223 applies the same voltage to the two piezoelectric material layers 50222 disposed on the same side surface of the metal elastic body 50221. When the high-frequency voltages applied by the power supply module 50223 to the piezoelectric material layers 50222 disposed on the two surfaces of the metal elastic body 50221 have a certain phase difference, the metal elastic body 50221 can produce a regular microscopic elliptical motion, thereby driving the synchronous motion of the driving feet 502213. Furthermore, because each driving foot 502213 abuts against the corresponding friction plate 50271, the friction force between the driving foot 502213 and the corresponding friction plate 50271 causes the driving foot 502213 to drive the friction plate 50271 in linear motion, thereby converting the microscopic motion of the resonant component 5022 into macroscopic linear motion of the friction plate 50271. Furthermore, since the friction plate 50271 is connected to the driven member 5026 , the driven member 5026 can achieve synchronous linear motion with the friction plate 50271 .

[0134] Referring to Figure 17 , Figure 17 is another schematic diagram of the structure of a driving device 502 provided in an embodiment of the present application. In this driving device 502, a resonant component 5022 includes a metal elastic body 50221 and a piezoelectric material layer 50222, as well as a driving shaft 50224. The specific configuration of the resonant component 5022 can be seen in Figure 18 , which is an exploded view of the driving device 502 shown in Figure 17 . The resonant component 5022 includes two piezoelectric material layers 50222, one of which is disposed on a first surface 502211 of the metal elastic body 50221, and the other piezoelectric material layer 50222 is disposed on a second surface 502212 of the metal elastic body 50221. The drive shaft 50224 passes through the two piezoelectric material layers 50222 and the metal elastic body 50221. The drive foot (not shown in FIG. 18 ) of the metal elastic body 50221 is connected to the drive shaft 50224, and the connection method may be, but is not limited to, bonding. In this way, the drive shaft 50224 can move synchronously with the drive foot, and the drive shaft 50224 can also be understood as the drive foot of the metal elastic body 50221.

[0135] The resonant assembly 5022 is located on one side of the device mounting bracket 5021. The device mounting bracket 5021 includes a first mounting portion 50213 and a second mounting portion 50214 disposed opposite each other. The first mounting portion 50213 includes a first mounting hole 502131, and the second mounting portion 50214 includes a second mounting hole 502141. The drive shaft 50224 sequentially passes through the first mounting hole 502131 and the second mounting hole 502141, so that the ends of the drive shaft 50224 are respectively mounted on the first mounting portion 50213 and the second mounting portion 50214. Furthermore, in the present application, the metal elastic body 50221 can be connected to the first mounting portion 50213 to achieve a connection between the metal elastic body 50221 and the device mounting bracket 5021.

[0136] 18 , in the drive device 502, the friction member 5027 includes two clamping portions 50272, which are interlocked with each other on either side of the drive shaft 50224 so that the drive shaft 50224 is clamped between the two clamping portions 50272. This allows the friction member 5027 to move linearly along the drive shaft 50224 under the drive of the high-frequency linear vibration output by the resonant assembly 5022.

[0137] Furthermore, the positive preload assembly 5028 can be used to apply normal positive pressure to each of the two clamping portions 50272, thereby pressing the two clamping portions 50272 toward the drive shaft 50224. In other words, the friction member 5027 can be pressed toward the drive shaft 50224, so that the two clamping portions 50272 clamp the drive shaft 50224, thereby increasing the friction between the clamping portions 50272 and the drive shaft 50224. In this embodiment of the present application, the positive preload assembly 5028 can include two springs, each located at two opposite ends of the friction member 5027, and connected to corresponding ends of the two clamping portions 50272. The connection method can be, but is not limited to, a threaded connection, so that each spring presses the corresponding ends of the two clamping portions 50272 together.

[0138] 17 and 18 , the friction member 5027 is positioned between the device mounting bracket 5021 and the driven member 5026. A first engaging portion 50267 is provided on the surface of the driven member 5026 facing the friction member 5027. Furthermore, the friction member 5027 has two clamping portions 50272 arranged along the direction from the device mounting bracket 5021 to the driven member 5026. For ease of description, the two clamping portions 50272 may be designated as a first clamping portion 50272 and a second clamping portion 50272, respectively. The first clamping portion 50272 is closer to the driven member 5026 than the second clamping portion 50272. Therefore, a second engaging portion (not shown in FIG. 18 ) may be provided on the surface of the first clamping portion 50272 facing the driven member 5026. In this way, the first clamping portion 50267 of the above-mentioned follower 5026 can be clamped with the second clamping portion of the first clamping portion 50272, so that the first clamping portion 50272 and the follower 5026 are clamped, thereby realizing the clamping of the follower 5026 and the friction member 5027, so that the friction member 5027 can drive the follower 5026 to move linearly therewith.

[0139] In an embodiment of the present application, the first clamping portion 50267 can be a protrusion or a groove, and the second clamping portion can be a groove or a protrusion, as long as the follower 5026 can be clamped with the first clamping portion 50272. Of course, the follower 5026 and the friction member 5027 can also be connected in other possible ways, which will not be introduced one by one here, but they should all be understood to fall within the scope of protection of this application. In addition, in another possible embodiment of the present application, the first clamping portion 50272 and the follower 5026 can also be an integrally formed structure, which is conducive to improving the movement consistency of the follower 5026 and the friction member 5027, thereby improving the driving accuracy of the resonance component 5022 on the displacement of the follower 5026, and further helping to improve the adjustment accuracy of the electrical parameters of the feed network system using the driving device.

[0140] The other structures of the driving device 502 shown in FIG17 may be configured with reference to any of the above embodiments, and will not be described in detail here.

[0141] In an embodiment of the present application, the driving device 502 of the power mechanism 5a can be, in addition to the form set based on the piezoelectric driving principle as described above, other miniaturized driving devices. For example, referring to Figure 19, in the feed network system shown in Figure 19, the driving device 502 of the power mechanism 5a includes a micro motor (not shown in Figure 19). In addition, the power mechanism 5a also includes a gear 503 and a rack 504, and the gear 503 and the rack 504 can serve as the driven member in the power mechanism 5a. During specific implementation, the gear 503 is engaged with the rack 504, and the rack 504 is connected to the sliding member 603. In this embodiment, the micro motor is used to drive the gear 503 to rotate, so that the rotation of the gear 503 can be converted into the linear motion of the rack 504, so that the gear 503 drives the rack 504 to move in a straight line, and then the rack 504 drives the sliding member 603 to move in a straight line.

[0142] It is worth mentioning that in the embodiment shown in FIG. 19 above, the rack 504 can be an independent structural member. The rack 504 and the sliding member 603 can be connected in the same manner as the connection between the driven member 5026 and the sliding member 603 in the embodiments shown in FIG. 13 and FIG. 14 above, and a detailed description thereof will not be given here. In addition, in some possible embodiments, the rack 504 and the sliding member 603 can be formed as an integral structure, that is, a rack surface is provided on the end of the sliding member 603 facing the drive device 502. This can effectively simplify the structure of the power mechanism 5a and make the structure of the feed network system more compact, thereby facilitating the miniaturization of the feed network system.

[0143] Referring to Figure 20, Figure 20 is another structural schematic diagram of the feed network system provided in an embodiment of the present application. In this feed network system, the driving device 502 of the power mechanism 5a also includes a micro motor (not shown in Figure 20). In addition, the power mechanism 5a also includes a worm gear 505 and a worm 506, and the worm gear 505 and the worm 506 can serve as the driven member in the power mechanism 5a. During specific implementation, the worm gear 505 and the worm 506 are meshed, and the worm 506 is connected to the sliding member 603. In this embodiment, the micro motor can be used to drive the worm gear 505 to rotate, so that the rotation of the worm gear 505 can be converted into the linear motion of the worm 506, so that the worm 506 drives the sliding member 603 to move in a straight line.

[0144] It is worth noting that in the embodiment shown in FIG. 20 , the worm 506 and the slider 603 can also be connected in the same manner as in the embodiments shown in FIG. 13 and FIG. 14 , and further description thereof is omitted. Furthermore, the other structures of the feed network system shown in FIG. 20 can be configured in the same manner as in any of the above-described embodiments, and further description thereof is omitted.

[0145] In addition, in a possible embodiment of the present application, the power mechanism 5a can also include a worm gear 505, and the sliding member 603 can include a worm 506. In this way, the power mechanism 5a and the sliding member 603 can be connected to each other through the engagement of the worm gear 505 and the worm 506. This can make the power mechanism 5a and the feeding network 6 more compact, thereby facilitating the miniaturization of the feeding network system.

[0146] Referring to Figure 21, Figure 21 is another structural schematic diagram of the feed network system provided in an embodiment of the present application. In this feed network system, the driving device 502 of the power mechanism 5a also includes a micro motor (not shown in Figure 21). In addition, the power mechanism 5a also includes a worm 506 and a rack 504, and the worm 506 and the rack 504 can serve as the driven members in the power mechanism 5a. During specific implementation, the worm 506 and the rack 504 are meshed, and the rack 504 is connected to the sliding member 603. In addition, the micro motor can be used to drive the worm 506 to rotate. In this way, the rotation of the worm 506 can be converted into the linear motion of the rack 504, so that the rack 504 drives the sliding member 603 to move in a straight line.

[0147] It is worth mentioning that in the embodiment shown in FIG. 21 above, the rack 504 can be an independent structural member. The rack 504 and the sliding member 603 can be connected in the same manner as the connection between the driven member 5026 and the sliding member 603 in the embodiments shown in FIG. 13 and FIG. 14 above, and a detailed description thereof will not be given here. In addition, in some possible embodiments, the rack 504 and the sliding member 603 can be formed as an integral structure, that is, a rack surface is provided on the end of the sliding member 603 facing the drive device 502. This can effectively simplify the structure of the power mechanism 5a and make the structure of the feed network system more compact, thereby facilitating the miniaturization design of the feed network system.

[0148] Referring to Figure 22, Figure 22 is a schematic diagram of another structure of a feed network system provided in an embodiment of the present application. In this feed network system, the drive device 502 of the power mechanism 5a includes a linear motor 502120. The output end of the linear motor 502120 can be directly connected to the sliding member 603, thereby driving the sliding member 603 in linear motion via the linear motor 502120. Because the linear force output by the linear motor 502120 can directly act on the sliding member 603 in this embodiment, no intermediate adapter is required between the two. This facilitates the simplification of the structure of the power mechanism 5a, thereby facilitating the miniaturization of the feed network system.

[0149] The above embodiments are only some exemplary descriptions of the driving device 502 of the power mechanism 5a of the feeding network system provided by the present application. On this basis, some adaptive deformations can be made to the driving device 502. For example, the structure of the follower arranged between the driving device 502 and the sliding member 603 can be adjusted to make the sliding member 603 move along a set curve, etc. They are not listed one by one here, but they should all be understood to fall within the scope of protection of the present application.

[0150] In the present application, in addition to being a dielectric phase shifter, the feed network 6 can also be a feed network with other possible configurations. For example, in the feed network system shown in FIG23 , the feed network 6 is a physical phase shifter, wherein, in the feed network 6, the fixing member 602 includes a metal strip line 6021, and the metal strip line 6021 is provided with a functional circuit, wherein the metal strip line 6021 can be a sheet metal strip line, and its material can be, but is not limited to, copper. In addition, the fixing member 602 can also include a support frame of insulating material (not shown in FIG23 ), which can be connected to the first shell 601 and the metal strip line 6021 to support the metal strip line 6021; or the fixing member 602 includes a printed circuit board, and the metal strip line 6021 is a metal trace in the printed circuit board. In addition, the sliding member 603 can be a metal slide, which is coupled and electrically connected to the metal strip line 6021 of the fixing member 602. In the feed network system, the phase of the output port of the phase shifter can be changed by sliding the sliding member 603 relative to the metal strip line 6021 of the fixing member 602 .

[0151] In the feeding network 6 shown in FIG23 , the phase of the output port of the phase shifter is adjusted by causing the slider 603 to move linearly relative to the metal strip line 6021 of the fixed part 602. Based on the design principle of the feeding network 6 shown in FIG23 , in some possible embodiments of the present application, the motion trajectory of the slider 603 relative to the metal strip line 6021 of the fixed part 602 can also be adaptively adjusted according to the specific application scenario. For example, referring to FIG24 a , FIG24 a is another structural schematic diagram of the feeding network 6 provided in an embodiment of the present application. In the feeding network 6 shown in FIG24 a , the slider 603 can also be a metal sheet, and the slider 603 can swing relative to the metal strip line 6021 around a rotation axis, so that the phase of the output port of the phase shifter can be changed by swinging the slider 603 relative to the metal strip line 6021 of the fixed part 602.

[0152] In addition, referring to FIG24b, FIG24b is another structural schematic diagram of a power mechanism 5a provided in an embodiment of the present application. The driving device 502 of the power mechanism 5a can be used to drive the sliding member 603 of the feed network 6 shown in FIG24a to swing. The driving device 502 may include a micro motor (not shown in FIG24b). In addition, the power mechanism 5a also includes a gear 503a and a gear 503b. The gear 503a and the gear 503b are meshed with each other. The gear 503b is connected to the sliding member 603, and the rotation center of the gear 503b coincides with the rotation center of the sliding member 603. The micro motor is used to drive the gear 503a to rotate, so that the gear 503a drives the gear 503b to rotate synchronously, thereby causing the gear 503b to drive the sliding member 603 to swing relative to the metal strip line 6021, thereby adjusting the phase of the output port of the phase shifter.

[0153] It will be appreciated that, in the present application, at least one of gear 503a and gear 503b is a half-gear structure. For example, in the power mechanism 5a shown in FIG24b , gear 503a is a complete gear structure, while gear 503b is a half-gear structure. This design helps reduce the size and weight of the power mechanism 5a, thereby facilitating a miniaturized design of the feed network system.

[0154] In addition, in a possible embodiment of the present application, the power mechanism 5a can also include a gear 503a, and the sliding member 603 can include a gear surface. In this way, the transmission connection between the power mechanism 5a and the sliding member 603 can be achieved by meshing the gear surface of the gear 503a with the gear surface of the sliding member 603. The power mechanism 5a and the feeding network 6 can be designed to be more compact, which is conducive to miniaturization of the feeding network system.

[0155] Referring to Figure 25, Figure 25 is another structural schematic diagram of the feed network system provided in an embodiment of the present application. In this embodiment, the fixed member 602 of the feed network 6 includes a printed circuit board, and the metal strip line 6021 is a metal trace in the printed circuit board. In addition, the sliding member 603 is provided with another functional circuit. In a specific implementation, as shown in Figure 25, the sliding member 603 also includes a printed circuit board, and the other functional circuit of the sliding member 603 is provided on the printed circuit board. In the embodiment of the present application, the other functional circuit of the sliding member 603 is coupled and electrically connected to the functional circuit of the metal strip line 6021. In this way, the topological form of the metal strip line 6021 can be changed by sliding the sliding member 603 relative to the metal strip line 6021, thereby changing the electrical parameters of the metal strip line 6021 to achieve the electrical function reconstruction of the metal strip line 6021.

[0156] The power mechanism of the feeding network system shown in FIG25 can be configured with reference to any of the above embodiments, and will not be described in detail here.

[0157] In the above embodiment of the present application, the plane where the sliding track of the slider 603 of the feed network 6 is located is parallel to the plane where the fixed member 602 is located, and in other possible embodiments of the present application, the plane where the sliding track of the slider 603 is located may also intersect with the plane where the fixed member 602 is located. For example, reference may be made to FIG26, which is another structural schematic diagram of the feed network provided in an embodiment of the present application. In this embodiment, the metal strip line 6021 of the fixed member 602 of the feed network 6 may be a sheet metal strip line, the material of which may be, but not limited to, copper. In addition, the fixed member 602 may further include a support frame of an insulating material (not shown in FIG26), which may be connected to the first shell 601 and the metal strip line 6021 to support the metal strip line 6021.

[0158] The slider 603 of the feed network 6 shown in FIG26 can be configured with reference to the slider 603 shown in FIG25 , and a detailed description thereof will not be repeated here. Furthermore, in FIG26 , the slider 603 can move relative to the fixed member 602 along the Z-direction, wherein the Z-direction is perpendicular to the plane on which the fixed member 602 lies. This ensures that the sliding trajectory of the slider 603 is perpendicular to the plane on which the fixed member 602 lies.

[0159] The power mechanism of the feeding network system shown in FIG26 can be configured with reference to any of the above embodiments, and will not be described in detail here.

[0160] It is worth mentioning that in the feeding network system shown in Figures 25 and 26, the feeding network 6 is a reconfigurable network. In this feeding network system, the functional circuits of the fixing part 602 and the sliding part 603 can be designed accordingly according to the specific application scenario, wherein the functional circuit of the fixing part 602 can exemplarily include at least one of a power divider, a bridge, a filter and a transmission line, and the other functional circuit of the sliding part 603 exemplarily includes at least one of a power divider, a bridge, a filter and a transmission line.

[0161] It can be understood that, in the present application, the reduction in the volume of the feed network is also conducive to the miniaturization design of the feed network system. There are many specific implementation methods for the miniaturization design of the feed network. For example, in a possible embodiment of the present application, the feed network may include multiple sub-function modules, and the functions that can be realized by the multiple sub-function modules may be the same or different. In addition, multiple sub-function modules can be stacked in the same direction or in different directions to ensure that there are at least two sub-function modules in the same projection plane, thereby realizing the layout of multiple sub-function modules in three-dimensional space, and multiple sub-function modules can be electrically connected through the adapter module according to a preset connection method. In this way, the internal space of the first shell of the feed network system can be fully utilized, which is conducive to the miniaturization design of the feed network.

[0162] In the above-mentioned feeding network, each sub-functional module may include a fixing member and a sliding member, wherein the fixing member and the sliding member of each sub-functional module may be configured with reference to any of the above-mentioned embodiments, which will not be described in detail here.

[0163] The above embodiments are only several exemplary descriptions of the feeding network and power mechanism provided in this application. On this basis, a series of variations can be made to the specific settings of the feeding network and the power mechanism, and different feeding networks and power mechanisms can be arbitrarily combined according to actual needs. They are not listed one by one here, but they should all be understood to fall within the scope of protection of this application.

[0164] In the feed network system provided in the embodiment of the present application, by integrating the power mechanism and the feed network into a whole, it is conducive to realizing the miniaturized design of the feed network system, thereby reducing the space occupied by the feed network system in the antenna, thereby improving the layout flexibility of the feed network system in the antenna, reducing the complexity of the antenna design, and facilitating the miniaturized design of the antenna.

[0165] Furthermore, when the feed network system provided in the above-described embodiments of the present application is applied to an antenna, the antenna can include at least two such feed network systems. Because the feed network system provided in the embodiments of the present application can be flexibly arranged within the antenna, at least two feed network systems can share a common control system, whereby the control system controls the drive device of each feed network system to drive the sliding member relative to the fixed member. This further enhances the antenna's integration, thereby reducing the antenna's complexity and overall size.

[0166] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
