[0002] This application claims priority to Chinese Patent Application No. 202411451225.9, filed on October 16, 2024, entitled "A Control Device, Feeding Network, Antenna and Communication Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of communication technology, and in particular to a control device, a power supply network, an antenna, and a communication device. Background Technology

[0004] The antenna feed network is the circuit that feeds radio frequency (RF) signals to the various radiating elements of the antenna. Adjustable feed network design is a crucial development direction for realizing intelligent and digital antennas, and RF switches are essential components for achieving this adjustable design. RF switches are connected in the feed network to control its on / off state, short circuits, offsets, and so on. For example, by controlling the on / off state of the feed network, RF switches can control the number or state of the radiating elements operating in the antenna, thereby adjusting the antenna beamwidth. Existing RF switches often suffer from problems such as excessive friction during state switching and poor control precision, which limits the adjustment of the feed network's state. Summary of the Invention

[0005] This application provides a control device, a power supply network, an antenna, and a communication device to improve the control accuracy and reliability of the control device.

[0006] In a first aspect, this application provides a control device comprising a movable plate, a fixed plate, and a drive structure. The movable plate and the fixed plate are disposed opposite each other along a first direction, and the movable plate is movable relative to the fixed plate along the first direction. A control element is disposed on the side surface of the movable plate facing the fixed plate, and a transmission conductor is disposed on the side surface of the fixed plate facing the movable plate. The orthographic projection of the transmission conductor in the first direction is in contact with or at least partially coincides with the orthographic projection of the control element in the first direction. The drive structure is drively connected to the movable plate and is used to drive the movable plate to move toward the fixed plate so that the control element contacts the transmission conductor; or, the drive structure is used to drive the movable plate to move away from the fixed plate so that the control element separates from the transmission conductor. The transmission conductor is used to connect to the feeder of a power supply network. In both cases where the control element contacts or separates from the transmission conductor, the transmission parameters or on / off state of the transmission conductor changes, thereby allowing control of the state of the feeder of the power supply network.

[0007] In this application, a movable plate reciprocates along a first direction to bring the control unit into contact with or separate from the transmission conductor, thereby regulating the state of the power supply network. During the contact or separation process between the control unit and the transmission conductor, the movable plate moves towards or away from the fixed plate. Therefore, there is no motion friction between the movable plate and the fixed plate, or between the control unit and the transmission conductor, thus eliminating the risk of frictional resistance and wear, and improving the reliability of the control device. Furthermore, based on the positional relationship between the movable plate and the fixed plate, the relative position of the control unit and the transmission conductor in the first direction remains constant. Therefore, even when the control unit is in contact with the transmission conductor, the control effect of the control unit on the transmission conductor can be guaranteed, thereby contributing to improved control accuracy of the control device.

[0008] In some embodiments, the control device may further include a housing and a base, with the base disposed within the housing and slidable relative to the housing in a first direction. The base is located on the side of the movable plate facing away from the fixed plate, and is fixedly connected to the movable plate. The base is also drive-connected to the drive structure. Therefore, the drive structure can drive the movable plate to move via the base, reducing the difficulty of the drive structure and the movable plate's transmission connection.

[0009] In some implementations, the control device also includes an elastic element disposed between the base and the movable plate. The elastic element can apply an elastic force to the movable plate in a direction away from the base. When the control device is in contact with the transmission conductor, the elastic force of the elastic element on the movable plate can make the control device fit more tightly against the transmission conductor, thereby ensuring the reliability of the control device.

[0010] For example, the elastic element can be an elastic block made of materials such as rubber. Alternatively, the elastic element can be a coil spring, a rubber spring, etc.

[0011] In some implementations, the drive structure includes a stud, a gear, and a drive rod. One end of the stud is fixed to the surface of the base facing away from the moving plate, and the other end extends in a first direction away from the base. The gear is rotatably mounted on the housing about the first direction, and its gear hole has an internal thread. The gear is threadedly connected to the stud through the threaded hole. The drive rod has a rack that meshes with the gear. The drive rod drives the gear to rotate during movement, causing the gear to drive the stud to move along the first direction, thereby driving the base and the moving plate to move synchronously, achieving the driving effect on the moving plate. Furthermore, based on the screw drive mechanism formed by the gear and stud, the gear can drive the stud with a relatively large rotational stroke to achieve a relatively small linear stroke. Therefore, the stroke control accuracy of the stud is relatively high, which also allows for better control of the movement accuracy of the moving plate.

[0012] In some embodiments, the housing includes a top wall with a through hole. The housing includes a bracket disposed on the outer wall of the top wall. The bracket includes a limiting wall and a connecting wall. The limiting wall and the top wall are opposite to and spaced apart along a first direction. The connecting wall connects the limiting wall and the top wall, and the limiting wall provides support and fixation. Along the first direction, a gear is positioned between the top wall and the limiting wall. A stud extends through the through hole between the top wall and the limiting wall to facilitate threaded connection with the gear. Due to the limiting effect of the top wall and the limiting wall on the gear in the first direction, the gear, driven by the drive rod, only undergoes rotational motion around the first direction. Therefore, the gear can reliably drive the stud to move along the first direction during rotation.

[0013] In some embodiments, the drive rod includes a drive surface, the height of which is set along a first direction; the drive surface is provided with a first protrusion, a second protrusion, and a third protrusion, the first protrusion, the second protrusion, and the third protrusion being spaced apart along the length direction of the drive rod, and along the first direction, the heights of the first protrusion, the second protrusion, and the third protrusion decreasing sequentially; a rack is disposed on the drive surface, the rack including a first sub-rack and a second sub-rack, the first sub-rack being located between the first protrusion and the second protrusion along the length direction of the drive rod, and the second sub-rack being located between the second protrusion and the third protrusion; along the first direction, at least a portion of the height of the first sub-rack is higher than the height of the second protrusion, and at least a portion of the height of the second sub-rack is lower than the height of the second protrusion;

[0014] The gear includes a first end face and a second end face disposed opposite to each other along a first direction. The gear includes a first tooth portion, a second tooth portion, a third tooth portion, a first tangential wall, and a second tangential wall. The first tooth portion and the first tangential wall are arranged along the first direction. The first tooth portion is disposed near the first end face, and at least a portion of each tooth in the first tooth portion extends beyond the first tangential wall along the radial direction of the gear. The second tooth portion and the second tangential wall are arranged along the first direction. The second tooth portion is disposed near the second end face, and at least a portion of each tooth in the second tooth portion extends beyond the second tangential wall along the radial direction of the gear. Along the circumferential direction of the gear, the third tooth portion connects the first tooth portion and the second tooth portion, and the teeth of the third tooth portion extend from the first end face to the second end face. The first tooth portion is used to mesh with the first sub-rack, and the height of the first tooth portion is higher than the height of the second convex ridge. The second tooth portion is used to mesh with the second sub-rack, and the height of the second tooth portion is lower than the height of the second convex ridge.

[0015] Through the above structural design of the drive rod and gear, the drive structure can reliably drive the moving plate to reciprocate along the first direction, and can also lock the moving plate in a state of contact or separation between the control device and the transmission conductor by disengaging the drive rod and gear, thereby effectively improving the working reliability of the control device. Furthermore, when the drive rod and gear are not engaged, the drive rod can also serve as a drive component for other parts in the power supply network, driving them to perform their corresponding functions. This simplifies the structural composition of the power supply network, reduces its layout space, and can reduce its cost to some extent.

[0016] In some implementations, the first end face and the second end face of the gear may be provided with bosses respectively. During the rotation of the gear, the boss on the first end face can prevent the limiting wall from rubbing against the gear teeth, and the boss on the second end face can prevent the top wall from rubbing against the gear teeth, thus improving the structural reliability of the gear.

[0017] In some implementations, along the direction perpendicular to the first tangential wall, the maximum length of each tooth in the first gear portion extending beyond the first tangential wall is L1; along the direction perpendicular to the drive surface, the thickness of the second convex strip is D2, and the thickness of the third convex strip is D3; L1, D2, and D3 satisfy: L1≤D2, L1≤D3. This dimensional design can reduce the sliding friction between the teeth of the first gear portion and the drive surface, thereby reducing gear wear and transmission resistance of the drive structure.

[0018] In some implementations, along the direction perpendicular to the second tangential wall, the maximum length of each tooth in the second gear portion extending beyond the second tangential wall is L2; ​​along the direction perpendicular to the drive surface, the thickness of the first convex strip is D1, and the thickness of the second convex strip is D2; L2, D2, and D3 satisfy: L2≤D1, L2≤D2. This dimensional design can reduce the sliding friction between the teeth of the second gear portion and the drive surface, thereby reducing gear wear and transmission resistance of the drive structure.

[0019] In some embodiments, the drive rod includes a drive surface, the height of which is set along the first direction; the drive surface is provided with a first protrusion and a second protrusion, the first protrusion and the second protrusion being spaced apart along the length direction of the drive rod; a rack is disposed on the drive surface, along the length direction of the drive rod, the rack is located between the first protrusion and the second protrusion, and along the first direction, at least a portion of the height of the rack is lower than the height of the first protrusion, and at least a portion of the height of the rack is lower than the height of the second protrusion;

[0020] The gear includes a first end face and a second end face disposed opposite each other along a first direction. The gear includes a first tooth portion, a second tooth portion, a third tooth portion, a first tangential wall, and a second tangential wall. The first tooth portion and the first tangential wall are arranged along the first direction. The first tooth portion is disposed near the second end face, and at least a portion of each tooth in the first tooth portion extends beyond the first tangential wall along the radial direction of the gear. The second tooth portion and the second tangential wall are arranged along the first direction. The second tooth portion is disposed near the second end face, and at least a portion of each tooth in the second tooth portion extends beyond the second tangential wall along the radial direction of the gear. Along the circumferential direction of the gear, the third tooth portion connects the first tooth portion and the second tooth portion, and the teeth of the third tooth portion extend from the first end face to the second end face. The first tooth portion is used to mesh with the rack, and the height of the first tooth portion is lower than the height of the first convex ridge. The second tooth portion is used to mesh with the rack, and the height of the second tooth portion is lower than the height of the second convex ridge.

[0021] Through the above structural design of the drive rod and gear, the drive structure can reliably drive the moving plate to reciprocate along the first direction, and can also lock the moving plate in a state of contact or separation between the control device and the transmission conductor by disengaging the drive rod and gear, thereby effectively improving the working reliability of the control device. Furthermore, when the drive rod and gear are not engaged, the drive rod can also serve as a drive component for other parts in the power supply network, driving them to perform their corresponding functions. This simplifies the structural composition of the power supply network, reduces its layout space, and can reduce its cost to some extent.

[0022] In some embodiments, along the direction perpendicular to the first tangential wall, the maximum length of each tooth in the first gear portion extending beyond the first tangential wall is L1', and along the direction perpendicular to the drive surface, the thickness of the first convex strip is D1'; L1' and D1' satisfy: L1'≤D1'. This dimensional design can reduce sliding friction between the first gear portion and the drive surface, thereby helping to reduce gear wear and transmission resistance of the drive structure.

[0023] In some embodiments, along the direction perpendicular to the second tangential wall, the maximum length of each tooth in the second gear portion extending beyond the second tangential wall is L2', and along the direction perpendicular to the drive surface, the thickness of the second convex strip is D2'; L2' and D2' satisfy: L2'≤D2'. This dimensional design can reduce sliding friction between the second gear portion and the drive surface, thereby helping to reduce gear wear and transmission resistance of the drive structure.

[0024] In some implementations, the control unit is a live wire. Depending on the relative position of the control unit and the transmission conductor, when the control unit is in contact with the transmission conductor, the control unit can be used to connect the input and output terminals of the transmission conductor, or to change the transmission parameters of the transmission conductor, thereby achieving regulation of the transmission conductor and enabling the control device to regulate the power supply network.

[0025] In some implementations, the transmission conductor includes a first sub-transmission conductor and a second sub-transmission conductor. One end of the first sub-transmission conductor is the input terminal of the transmission conductor, and one end of the second sub-transmission conductor is the output terminal. The other ends of the first and second sub-transmission conductors are spaced apart, and the orthographic projections of the first and second sub-transmission conductors in the first direction do not coincide. The orthographic projection of the first sub-transmission conductor in the first direction is connected to or at least partially coincides with the orthographic projection of the control unit in the first direction, and the orthographic projection of the second sub-transmission conductor in the first direction is connected to or at least partially coincides with the orthographic projection of the control unit in the first direction. When the control unit is separated from the transmission conductor, the input terminal and the output terminal of the transmission conductor are disconnected; when the control unit is in contact with the transmission conductor, the input terminal and the output terminal of the transmission conductor are connected through the control unit. Therefore, the control device can change the conduction state of the power supply network during state switching.

[0026] In some implementations, the transmission conductor includes a first sub-transmission conductor, a second sub-transmission conductor, and a third sub-transmission conductor. One end of the first sub-transmission conductor is the input terminal of the transmission conductor. One ends of the second and third sub-transmission conductors are respectively the first and second output terminals of the transmission conductor. The other end of the second sub-transmission conductor is electrically connected to the other end of the first sub-transmission conductor. The other end of the third sub-transmission conductor is spaced apart from the other end of the first sub-transmission conductor. The orthographic projection of the third sub-transmission conductor in a first direction does not coincide with the orthographic projection of the first sub-transmission conductor in the first direction, nor does it coincide with the orthographic projection of the second sub-transmission conductor in the first direction. The orthographic projection of the first sub-transmission conductor in the first direction is connected to or at least partially coincides with the orthographic projection of the adjustment control in the first direction. The orthographic projection of the third sub-transmission conductor in the first direction is connected to or at least partially coincides with the orthographic projection of the adjustment control in the first direction. When the adjustment control is separated from the transmission conductor, the input terminal and the second output terminal of the transmission conductor are disconnected; when the adjustment control is in contact with the transmission conductor, the input terminal and the second output terminal of the transmission conductor are connected through the adjustment control. Therefore, the control device can change the conduction state of the power supply network when switching states.

[0027] In some implementations, the control unit includes a first sub-control unit and a second sub-control unit. The orthographic projection of the first sub-transmission conductor in a first direction is connected to or at least partially coincides with the orthographic projection of the first sub-control unit in the first direction. The orthographic projection of the third sub-transmission conductor in the first direction is connected to or at least partially coincides with the orthographic projection of the first sub-control unit in the first direction. The orthographic projection of the second sub-transmission conductor in the first direction is at least partially coincident with the orthographic projection of the second sub-control unit in the first direction. When the control unit is in contact with the transmission conductor, the first sub-control unit can connect the input terminal of the transmission conductor to the second output terminal, and the second sub-control unit can be at least partially attached to the second sub-transmission conductor, so that the second sub-control unit can adjust the transmission parameters of the second sub-transmission conductor, thereby adjusting the transmission state of the power supply network.

[0028] In some implementations, the control unit can be a strip wire or a dielectric block. The transmission conductor includes a first sub-transmission conductor, a second sub-transmission conductor, and a third transmission conductor. One end of the first sub-transmission conductor is the input terminal of the transmission conductor. One end of the second sub-transmission conductor and one end of the third sub-transmission conductor are respectively the first and second output terminals of the transmission conductor. The other ends of the first, second, and third sub-transmission conductors are interconnected. The orthographic projection of the third sub-transmission conductor in a first direction at least partially coincides with the orthographic projection of the control unit in the first direction. When the control unit is in contact with the transmission conductor, it can at least partially abut against the third sub-transmission conductor. Therefore, the control unit can adjust the transmission parameters of the third sub-transmission conductor, thereby controlling the transmission state of the power supply network.

[0029] In some implementations, the control line can be a strip or a dielectric block. The transmission conductor is a continuous, integral structure, and its orthographic projection in the first direction at least partially coincides with the orthographic projection of the control line in the first direction. When the control unit is in contact with the transmission conductor, the control unit can at least partially abut against the transmission conductor, thus allowing the control unit to regulate the transmission parameters of the transmission conductor, and consequently, regulate the transmission state of the power supply network.

[0030] Secondly, this application also provides a feed network, which includes a feed line and a control device as described in any of the embodiments of the first aspect. The control device can be used to control the state of the feed line, such as the feed line being on or off, short-circuited, or offset, thereby adjusting the working state of the radiating element connected to the feed network and realizing the adjustment of the antenna beam.

[0031] In some implementations, the feeder network also includes a phase shifter connected in the feeder. A drive structure is driven by the phase shifter and is also used to drive the phase shifter to switch between operating and non-operating states. In this application, the phase shifter and the control device can share the same drive structure, thus simplifying the structure of the feeder network, reducing the layout space of the feeder network, and reducing the cost of the feeder network to a certain extent.

[0032] For example, the drive rod can drive the phase shifter to switch between an active and inactive state while disengaged from the gear.

[0033] Thirdly, this application also provides an antenna, which includes multiple radiating elements and the feed network described in the second aspect. The feed line of the feed network includes a radio frequency (RF) input terminal and multiple RF output terminals. The RF input terminal is used to receive RF signals, and the multiple RF output terminals are respectively connected to multiple radiating elements. The input terminal of a phase shifter is connected to the RF input terminal, and the output terminal of the phase shifter is connected to at least one RF output terminal to adjust the phase of at least one radiating element corresponding to at least one RF output terminal. The input terminal of the transmission conductor of a control device is connected to the RF input terminal, and the output terminal of the transmission conductor of the control device is connected to at least one RF output terminal to control the state of the feed network. Exemplarily, the control device can control the feed line state between the RF input terminal and at least one RF output terminal, such as feed line on / off, short circuit, offset, etc.

[0034] Fourthly, this application also provides a communication device, which includes a radio frequency (RF) processing unit and the antenna described in the third aspect. The RF processing unit is connected to the RF input terminal of the feed line of the feed network. The feed network can feed the RF signal received from the RF processing unit to the radiating unit according to a certain amplitude and phase, or transmit the wireless signal received by the radiating unit to the RF processing unit according to a certain amplitude and phase, thereby enabling the communication device to achieve wireless communication functionality.

[0079] Figure 2 is a schematic diagram of a communication device 1000 provided in an embodiment of this application. Figure 2 illustrates the communication device 1000 as a base station. In the following embodiments, the base station and the communication device 1000 use the same reference numerals. Referring to Figure 2, the base station 1000 includes a base station antenna feeder system. In practical applications, the base station antenna feeder system mainly includes an antenna 100, a cable 200, and a grounding device 300, etc. The antenna 100 can be mounted on a mast 500 using a mounting bracket 400. The mounting bracket 400 can adjust the downtilt angle of the antenna 100 to adjust the signal coverage range of the antenna 100 to a certain extent.

[0080] In this embodiment, the base station 1000 may further include a radio frequency (RF) processing unit 600 and a baseband processing unit 700. The RF processing unit 600 can perform frequency selection, amplification, and down-conversion processing on the signal received by the antenna 100, converting it into an intermediate frequency (IF) signal or a baseband signal and sending it to the baseband processing unit 700. Alternatively, the RF processing unit 600 can up-convert and amplify the IF signal emitted by the baseband processing unit 700, converting it into a wireless signal and transmitting it through the antenna 100. The baseband processing unit 700 can be connected to the feed network of the antenna 100 via the RF processing unit 600. In some embodiments, the RF processing unit 600 may also be referred to as a remote radio unit (RRU), and the baseband processing unit 700 may also be referred to as a baseband unit (BBU).

[0081] The radio frequency (RF) processing unit 600 and the baseband processing unit 700 can be connected via a cable. In one embodiment, the RF processing unit 600 and the baseband processing unit 700 may be located at the distal end of the antenna 100. In another embodiment, the RF processing unit 600 may be integrated with the antenna 100, and the baseband processing unit 700 may be located at the distal end of the antenna 100. In this example, the RF processing unit 600 and the antenna 100 may be collectively referred to as an active antenna unit (AAU).

[0082] Figure 3 is a schematic diagram of the structure of an antenna 100 provided in an embodiment of this application. Referring to Figure 3, in this embodiment, the antenna includes a feed network 110 and multiple radiating elements 120. The feed network 110 can feed radio frequency signals received from the radio frequency processing unit to the radiating elements 120 according to a certain amplitude and phase, or transmit wireless signals received by the radiating elements 120 to the radio frequency processing unit according to a certain amplitude and phase. The radiating element 120 can also be called an antenna element, vibrator, or radiator. The radiating element 120 is a unit constituting the basic structure of the antenna 100, and it can effectively transmit or receive electromagnetic waves. The radiating elements 120 can be divided into single-polarized and dual-polarized types. In practical applications, the type of radiating element can be reasonably selected according to actual needs.

[0083] In some embodiments, the antenna 100 further includes a reflector 130, and the radiating elements 120 can be arranged in an array on the reflector 130. The reflector 130 can also be referred to as a floor, antenna panel, or reflective surface, etc. When the antenna 100 receives a signal, the reflector 130 can reflect and focus the antenna signal on the receiving point. When the antenna 100 transmits a signal, the signal can be directed to the reflector 130 and reflected back by the reflector 130.

[0084] In some embodiments, the antenna 100 further includes a radome 140, which can be used to house the aforementioned feed network 110, radiating element 120, reflector 130, and other components. The radome 140 has good electromagnetic wave penetration to ensure normal transmission and reception of electromagnetic waves between the radiating element 120 and the outside world. In addition, the radome 140 also has good stress resistance and oxidation resistance to withstand the corrosion of harsh external environments. Exemplarily, the material of the radome 140 includes, but is not limited to, thermosetting and thermoplastic materials such as fiberglass, polyvinyl chloride (PVC), or plastics copolymerized from styrene, acrylonitrile, and acrylate rubber (ASA plastic).

[0085] Figure 4 is a partial structural schematic diagram of an antenna 100 provided in an embodiment of this application. Referring to Figure 4, the feed network 110 includes a feed line 111, a phase shifter 112, and a control device 113. The feed line 111 includes a radio frequency input terminal 111a and multiple radio frequency output terminals 111b. The radio frequency input terminal 111a is connected to the radio frequency processing unit of a communication device, and the multiple radio frequency output terminals 111b are respectively connected to multiple radiating elements 120 to transmit signals between the radio frequency processing unit and the radiating elements 120. The number of phase shifters 112 and control devices 113 can both be one or more. The input terminal of each phase shifter 112 is connected to the radio frequency input terminal 111a, and the output terminal of each phase shifter 112 is connected to at least one radio frequency output terminal 111b to adjust the phase of at least one radiating element 120 corresponding to the at least one radio frequency output terminal 111b; the input terminal of each control device 113 is connected to the radio frequency input terminal 111a, and the output terminal of each control device 113 is connected to at least one radio frequency output terminal 111b to control the state of the feed network 110, such as the on / off state, short circuit, offset, etc. of the feed line 111 of the feed network 110.

[0086] In some embodiments, the power supply network further includes a housing, within which the feeder 111 can be housed to protect it from corrosion or damage caused by the external environment, thereby enabling the feeder 111 to stably transmit signals between the radio frequency processing unit and the radiation unit 120. The phase shifter 112 and the control device 113 may be housed within or outside the housing; this application does not limit their placement in this regard.

[0087] In this embodiment, a sub-feed line is formed between the RF input terminal 111a and each RF output terminal 111b of the feed line 111, and each sub-feed line outputs an RF signal to a corresponding radiating element 120. In one implementation, at least two sub-feed lines have different physical lengths. In this case, the phase delay of the RF signals transmitted in the sub-feed lines with different physical lengths will also be different, thereby achieving a non-uniform phase feeding effect. In other words, the feed network 110 in this implementation is a non-uniform feed network. The non-uniform feed network can, to a certain extent, disrupt the periodicity of each radiating element 120, thereby suppressing grating lobes and helping to improve the radiation performance of the antenna 100. Of course, in another implementation, multiple sub-feed lines can also have the same physical length. In this case, the feed network 110 is an equiphase feed network.

[0088] Multiple RF output terminals 111b can be connected in parallel or in series, and this application does not impose any restrictions on this. For example, the embodiment shown in Figure 4 illustrates a case where multiple RF output terminals 111b are connected in parallel. In this embodiment, the feeder 111 includes multiple branches 1111, and each branch 1111 can include multiple sub-branches 11111. The input terminal of each branch 1111 is connected to the RF input terminal 111a, and the multiple output terminals of each branch 1111 are respectively connected to the input terminals of the multiple sub-branches 11111. The multiple output terminals of each sub-branch 11111 can each serve as the RF output terminal 111b of the feeder 111.

[0089] In the feed network 110 of the above form, the phase shifter 112 can be disposed at the radio frequency input terminal 111a, in which case the phase shifter 112 can adjust the phase of all radiating elements 120; or, the phase shifter 112 can be disposed at the input terminal of branch 1111, in which case the phase shifter 112 can adjust the phase of multiple radiating elements 120 corresponding to the output terminals of multiple sub-branches 11111 in the branch 1111; or, the phase shifter 112 can be disposed at the input terminal of sub-branch 11111, in which case the phase shifter 112 can adjust the phase of multiple radiating elements 120 corresponding to multiple output terminals of the sub-branch 11111; or, the phase shifter 112 can be disposed between the input terminal of sub-branch 11111 and one or more output terminals of sub-branch 11111, in which case the phase shifter 112 can adjust the phase of radiating elements 120 corresponding to one or more output terminals of the sub-branch 11111. Figure 4 shows one implementation of the phase shifter 112 being located at the radio frequency input terminal 111a.

[0090] Similarly, the control device 113 can be located at the RF input terminal 111a, in which case the control device 113 can control the feed line state between the RF input terminal 111a and all the radiating units 120; or, the control device 113 can be located at the input terminal of the branch 1111, in which case the control device 113 can control the feed line state between the RF input terminal 111a and the multiple radiating units 120 corresponding to the branch 1111; or, the control device 113 can be located at the input terminal of the sub-branch 11111, in which case the control device 113 can control the feed line state between the RF input terminal 111a and the multiple radiating units 120 corresponding to the sub-branch 11111; or, the control device 113 can be located between the input terminal of the sub-branch 11111 and one or more output terminals of the sub-branch 11111, in which case the control device 113 can control the feed line state between the RF input terminal 111a and one or more output terminals of the sub-branch 11111. Figure 4 shows one implementation of the control device 113 being located at the input of sub-branch 11111.

[0091] It should be noted that the structure of the power supply network 110 shown in Figure 4 is only an example. In other implementations, the power supply network 110 can also adopt other design forms, such as the parallel form of more levels of branches 1111, or the form of series-parallel combination, etc., which will not be elaborated in detail here.

[0092] In the embodiments of this application, the phase shifter 112 can be, but is not limited to, a reflective phase shifter, a loaded-line phase shifter, a switch-line phase shifter, a filter-type phase shifter, etc., and this application does not impose any limitations on this. Taking a reflective phase shifter as an example, its basic principle is to connect a reactive load in a uniform transmission conductor, and use the switching to change the impedance characteristics of the load, thereby changing the phase of the load reflection coefficient, so as to generate a phase shift between the incident signal and the output signal. As another example, the loaded-line phase shifter's basic principle is to connect a controllable reactive element in parallel or series in a uniform transmission conductor, and introduce a phase shift in the line by changing the reactance value. Although the phase shifting principles of different types of phase shifters 112 are different, all types of phase shifters 112 basically achieve the phase shifting function by changing their own operating state. Therefore, phase shifters 112 are generally equipped with a driving component to change the operating state of the phase shifter 112. The structure of the driving component is not limited, as long as it can be connected to the relevant components in the phase shifter 112 that affect its operating state.

[0093] Figure 5 is a schematic diagram of an installation structure of the control device 113 provided in an embodiment of this application; Figure 6 is a partial structural schematic diagram of the control device 113 shown in Figure 5; and Figure 7 is an exploded view of the control device 113 shown in Figure 5. Referring together to Figures 5 to 7, the control device 113 includes a moving plate 1132, a fixed plate 1133, and a driving structure 1134. The movable plate 1132 and the fixed plate 1133 are arranged opposite each other along a first direction, and the movable plate 1132 can move relative to the outer shell 1131 along the first direction. An adjustment control 11321 is provided on the side surface of the movable plate 1132 facing the fixed plate 1133. A transmission conductor 11331 is provided on the side surface of the fixed plate 1133 facing the movable plate 1132. The orthographic projection of the transmission conductor 11331 in the first direction is connected to or at least partially overlaps with the orthographic projection of the adjustment control 11321 in the first direction. The driving structure 1134 is used to drive the movable plate 1132 to move along the first direction toward or away from the fixed plate 1133, so that the adjustment control 11321 of the movable plate 1132 contacts or separates from the transmission conductor 11331 of the fixed plate 1133.

[0094] In this embodiment, the control device 113 may further include a housing 1131, and a movable plate 1132 may be slidably disposed on the housing 1131 along a first direction. The housing 1131 may be fixed to the housing 114 of the power supply network to achieve its installation and positioning in the power supply network. The housing 1131 includes a top wall 11311, a first side wall 11312, and a second side wall 11313. The first side wall 11312 and the second side wall 11313 are disposed opposite to each other, and the first side wall 11312 and the second side wall 11313 are respectively fixedly connected to the top wall 11311 to enclose and form an accommodating space for accommodating the movable plate 1132. Along the first direction, the top wall 11311 is disposed opposite to the fixed plate 1133, and the movable plate 1132 may reciprocate within the space between the top wall 11311 and the fixed plate 1133.

[0095] In some embodiments, the fixing plate 1133 can also be fixed to the housing 114 of the power supply network to achieve relative fixation with the outer shell 1131. In other embodiments, the fixing plate 1133 can also be directly fixedly connected to the outer shell 1131. For example, the fixing plate 1133 can be fixedly connected to the first side wall 11312 and the second side wall 11313 of the outer shell 1131.

[0096] Referring again to Figures 5 to 7, in this embodiment, the control device 113 may further include a base 1135. The base 1135 is slidably disposed within the housing 1131 along a first direction, and the base 1135 is located on the side of the movable plate 1132 facing away from the fixed plate 1133. The side of the base 1135 facing the movable plate 1132 is fixedly connected to the movable plate 1132, and the side of the base 1135 facing away from the movable plate 1132 is drive-connected to the drive structure 1134. In this way, the drive structure 1134 can drive the movable plate 1132 to move through the base 1135, reducing the difficulty of the drive structure 1134 and the movable plate 1132 in transmission connection.

[0097] In one implementation, a fixing post 11351 is provided on the side surface of the base 1135 facing the movable plate 1132. Correspondingly, the movable plate 1132 is provided with a fixing hole 11322. Along a first direction, the fixing post 11351 is fixed opposite to the fixing hole 11322. The fixing post 11351 can be fixed in the fixing hole 11322 by interference fit or snap-fit, thereby achieving a fixed connection between the base 1135 and the movable plate 1132. There can be multiple fixing posts 11351 and fixing holes 11322, with each fixing post 11351 fixed in a corresponding fixing hole 11322. The connection strength between the base 1135 and the movable plate 1132 is improved through the cooperation between multiple pairs of fixing posts 11351 and fixing holes 11322. It is worth mentioning that the fixing hole 11322 can be located on the movable plate 1132, avoiding the area of ​​the adjustment control 11321, to prevent affecting the routing direction of the adjustment control 11321.

[0098] Figure 8a is a side sectional view of the control device 113 shown in Figure 7 in a first state, and Figure 8b is a side sectional view of the control device 113 shown in Figure 7 in a second state. Referring to Figures 8a and 8b together, when the driving structure 1134 drives the moving plate 1132 to move away from the fixed plate 1133 until the control switch 11321 separates from the transmission conductor 11331, the transmission conductor 11331 is not affected by the control switch 11321, or in other words, the control switch 11321 has no control effect on the transmission conductor 11331, and the control device 113 is in the first state; when the driving structure 1134 moves the moving plate 1132 towards the fixed plate 1133 until the control switch 11321 contacts the transmission conductor 11331, the control switch 11321 can change the transmission parameters or on / off state of the transmission conductor 11331, and the control device 113 is in the second state. As can be seen, in this embodiment, the moving plate 1132 is driven to reciprocate along the first direction by the driving structure 1134, which can switch the control device 113 between the first state and the second state. During the state switching process, the moving plate 1132 moves closer to or further away from the fixed plate 1133. Therefore, there is no motion friction between the moving plate 1132 and the fixed plate 1133, and between the control device 11321 and the transmission conductor 11331. This eliminates the risk of frictional resistance and wear.

[0099] The transmission conductor 11331 includes an input terminal and one or more output terminals. The input terminal can be used to connect to the RF input terminal of the feed network, and the one or more output terminals can be used to connect to the RF output terminal of the feed network. For example, in the feed network 110 shown in FIG. 4, the transmission conductor 11331 includes an input terminal and an output terminal. The input terminal of the transmission conductor 11331 is connected to the input terminal of the sub-branch 11111, and thus to the RF input terminal 111a of the feed network 110. The output terminal of the transmission conductor 11331 is connected to the output terminal of the sub-branch 11111, that is, to the RF output terminal 111b of the feed network 110. When the control device 113 switches between the first state and the second state, the feeder state between the input terminal and the output terminal of the sub-branch can be controlled.

[0100] In some embodiments, an elastic element 1136 may be provided between the base 1135 and the movable plate 1132. The deformation direction of the elastic element 1136 is arranged along a first direction, and the elastic element 1136 elastically abuts against both the base 1135 and the movable plate 1132. Therefore, the elastic element 1136 can apply an elastic force to the movable plate 1132 in a direction away from the base 1135. When the control device 113 is in the second state, the downward pressing force of the elastic element 1136 on the movable plate 1132 can make the movable plate 1132 fit more tightly against the fixed plate 1133, thereby enabling the control control 11321 to reliably contact the transmission conductor 11331 and improving the operational reliability of the control device 113 in the second state.

[0101] The specific type of the elastic element 1136 is not limited. For example, in the embodiments shown in Figures 8a and 8b, the elastic element 1136 is an elastic block made of materials such as rubber. Alternatively, referring to the side sectional view of another control device 113 provided in the second state of the embodiment of this application shown in Figure 9, in this embodiment, the elastic element 1136 can be a metal spring. Of course, in some other embodiments, the elastic element 1136 can also be a structure with elastic deformation characteristics such as a coil spring or a rubber spring, which will not be illustrated here.

[0102] Please continue referring to Figures 7, 8a, and 8b. In this embodiment, the drive structure 1134 may include a stud 11341, a gear 11342, and a drive rod 11343. The stud 11341 is fixed to the base 1135. Specifically, the stud 11341 is fixed to the side of the base 1135 facing away from the moving plate 1132, and extends along a first direction. The gear 11342 is rotatably mounted on the housing 1131, and its rotation axis is oriented along the first direction. The gear hole of the gear 11342 has an internal thread, allowing it to be threadedly connected to the stud 11341. Therefore, the gear 11342 and the stud 11341 can form a lead screw mechanism. The gear 11342 can be considered as the nut of the lead screw mechanism, and the stud 11341 can be considered as the lead rod of the lead screw. The drive rod 11343 is slidably mounted on the housing 114 of the power supply network. The drive rod 11343 is provided with a rack 113431, which meshes with the gear 11342. The drive rod 11343 can drive the gear 11342 to rotate when moving. Based on the working principle of the lead screw structure, the gear 11342 can drive the stud 11341 to move in the first direction when rotating, thereby driving the base 1135 and the moving plate 1132 to move synchronously, realizing the driving effect on the moving plate 1132.

[0103] As those skilled in the art will know, a lead screw mechanism is a transmission mechanism that drives a small stroke (linear motion) with a large stroke (rotational motion). Specifically, in this embodiment, the gear 11342 can drive the stud 11341 with a relatively large rotational stroke to achieve a relatively small linear stroke. Therefore, the stroke control accuracy of the stud 11341 is relatively high, which also allows for better control of the movement accuracy of the moving plate 1132. In addition, this transmission method also has the characteristics of low resistance and high stability in the motion process, thus enabling efficient and reliable switching of the state of the control device 113.

[0104] It should be understood that the direction of movement of the drive rod 11343 determines the direction of rotation of the gear 11342, and the direction of rotation of the gear 11342 determines the direction of movement of the stud 11341, the base, and the moving plate 1132. Therefore, by controlling the direction of movement of the drive rod 11343, the moving plate 1132 can be controlled to move towards or away from the fixed plate 1133.

[0105] In some embodiments, the drive structure 1134 may further include a drive motor, which is connected to the drive rod 11343 to drive the drive rod 11343 to reciprocate. In one implementation, the drive motor is a rotary motor, which can be connected to the drive rod 11343 via a transmission mechanism to convert the rotational motion output by the rotary motor into linear motion. In another implementation, the drive motor is a linear motor, which can directly output linear motion to the drive rod 11343.

[0106] In this embodiment, the top wall 11311 of the outer casing 1131 is provided with a bracket 11314, which includes a limiting wall 113141 and a connecting wall 113142. The limiting wall 113141 and the top wall 11311 are positioned opposite each other and spaced apart along a first direction; the connecting wall 113142 connects the limiting wall 113141 and the top wall 11311 to support and fix the limiting wall 113141. Exemplarily, the limiting wall 113141 and the top wall 11311 may be substantially parallel, and the distance between them is equal to or slightly greater than the thickness of the gear 11342. There may be two connecting walls 113142, which are respectively supported on both sides of the limiting wall 113141.

[0107] Gear 11342 is located between top wall 11311 and limiting wall 113141, and the teeth of gear 11342 are positioned beyond the edge of limiting wall 113141 where they are not connected to connecting wall 113142, so as to mesh with rack 113431 of drive rod 11343. In addition, top wall 11311 is provided with through hole 113111, through which stud 11341 extends to the space between top wall 11311 and limiting wall 113141, so as to thread it with gear 11342. Since the two ends of the gear 11342 are restricted by the top wall 11311 and the limiting wall 113141, the gear 11342 only has rotational motion around the first direction under the drive of the drive rod 11343. This enables the gear 11342 to reliably drive the stud 11341 to move along the first direction during rotation.

[0108] Figure 10a is a structural schematic diagram of a drive rod 11343 provided in an embodiment of this application, and Figure 10b is a plan view of the drive rod 11343 shown in Figure 10a. Referring to Figures 10a and 10b together, in this embodiment of the application, the drive rod 11343 includes a drive surface 11343a. The height direction of the drive surface 11343a is set along a first direction. The drive surface 11343a is provided with a first protrusion 113432, a second protrusion 113433, and a third protrusion 113434. The first protrusion 113432, the second protrusion 113433, and the third protrusion 113434 are arranged at intervals along the length direction of the drive rod 11343. Along the first direction, the height of the first protrusion 113432 is higher than the height of the second protrusion 113433, and the height of the second protrusion 113433 is higher than the height of the third protrusion 113434. For example, the first protrusion 113432 is disposed near the top surface of the drive rod 11343 along the height direction, the third protrusion 113434 is disposed near the bottom surface of the drive rod 11343 along the height direction, and the second protrusion 113433 is disposed centrally in the height direction of the drive surface 11343a. A rack is disposed on the drive surface 11343a, and the rack includes a first sub-rack 113435 and a second sub-rack 113436. Along the length direction of the drive rod 11343, the first sub-rack 113435 is located between the first protrusion 113432 and the second protrusion 113433, and the second sub-rack 113436 is located between the second protrusion 113433 and the third protrusion 113434; and, along the first direction, at least a portion of the height of the first sub-rack 113435 is higher than... The height of the second protrusion 113433 is such that at least a portion of the height of the second sub-rack 113436 is lower than the height of the second protrusion 113433. That is to say, the first sub-rack 113435 may be higher in overall height than the second protrusion 113433, or it may be higher in a partial height than the second protrusion 113433. The second sub-rack 113436 may be lower in overall height than the second protrusion 113433, or it may be lower in a partial height than the second protrusion 113433.

[0109] Figure 11a is a structural schematic diagram of a gear 11342 provided in an embodiment of this application, and Figure 11b is a plan view of the gear 11342 shown in Figure 11a. Referring to Figures 11a and 11b together, in this embodiment of the application, the gear 11342 includes a first end face 11342a and a second end face 11342b disposed opposite to each other along a first direction. The gear 11342 includes a first tooth portion 113421, a second tooth portion 113422, a third tooth portion 113423, a first tangential wall 113424, and a second tangential wall 113425. A first tooth portion 113421 and a first tangential wall 113424 are arranged along a first direction. The first tooth portion 113421 is disposed near a first end face 11342a, and the first tangential wall 113424 is disposed near a second end face 11342b. Along the radial direction of the gear 11342, at least a portion of each tooth in the first tooth portion 113421 extends beyond the first tangential wall 113424. A second tooth portion 113422 and a second tangential wall 113425 are arranged along the first direction. The second tooth portion 113422 is disposed near a second end face 11342b, and the second tangential wall 113425 is disposed near a first end face 11342a. Along the radial direction of the gear 11342, at least a portion of each tooth in the second tooth portion 113422 extends beyond the second tangential wall 113425. Along the circumference of gear 11342, the third tooth 113423 connects the first tooth 113421 and the second tooth 113422, and the teeth of the third tooth 113423 can extend from the first end face 11342a to the second end face 11342b.

[0110] In one implementation, the first end face 11342a and the second end face 11342b of the gear 11342 may be provided with bosses 113426 respectively. During the rotation of the gear 11342, the bosses 113426 on the first end face 11342a can prevent the limiting wall from rubbing against the teeth of the gear 11342, and the bosses 113426 on the second end face 11342b can prevent the top wall from rubbing against the teeth of the gear 11342. Therefore, the structural reliability of the gear 11342 can be improved.

[0111] In this embodiment, the positions of the first tangential wall 113424 and the second tangential wall 113425 on the periphery of the gear 11342 can be designed according to the requirements of the rotational stroke of the gear 11342. For example, in the embodiment shown in FIG11b, the angle between the normal of the first tangential wall 113424 and the normal of the second tangential wall 113425 is approximately 180°.

[0112] Of course, in some other embodiments, the angle between the normal of the first tangential wall 113424 and the normal of the second tangential wall 113425 can also be other angles, such as 60°, 90°, 120°, 240°, etc. For example, Figure 11c shows a case where the angle between the normal of the first tangential wall 113424 and the normal of the second tangential wall 113425 is 60°, and Figure 11d shows a case where the angle between the normal of the first tangential wall 113424 and the normal of the second tangential wall 113425 is 90°.

[0113] Figures 12a to 12h are schematic diagrams of the transmission connection of the drive rod 11343 shown in Figure 10a and the gear 11342 shown in Figure 11a in different states. Referring also to Figures 12a to 12h, in the embodiment of this application, the first tooth 113421 is used to mesh with the first sub-rack 113435, and the second tooth 113422 is used to mesh with the second sub-rack 113436. The height of the first tooth 113421 is higher than the height of the second protrusion 113433, and the height of the second tooth 113422 is lower than the height of the second protrusion 113433. The first tangential wall 113424 can fit with the first protrusion 113432 and the second protrusion 113433, and the second tangential wall 113425 can fit with the second protrusion 113433 and the third protrusion 113434. The driving process of the driving structure in this embodiment will be described below with reference to the two states of the control device 113 shown in Figures 8a and 8b.

[0114] Referring first to Figure 12a, in this transmission state, the second tangential wall 113425 of the gear 11342 is in contact with the second protrusion 113433 of the drive rod 11343. The second tooth of the gear 11342 is located below the second protrusion 113433 of the drive rod 11343. When the drive rod 11343 moves to the left or right, since there is no meshing relationship between the drive rod 11343 and the gear 11342, the gear 11342 does not rotate, and the stud 11341 naturally does not move. The state of the control device 113 remains unchanged. For example, in the transmission state shown in Figure 12a, the control device 113 remains in the first state.

[0115] Along the direction perpendicular to the second tangential wall 113425, the maximum length of each tooth in the second tooth portion 113422 extending beyond the second tangential wall 113425 is L2 (refer to Figure 12c). Along the direction perpendicular to the drive surface 11343a, the thickness of the second protrusion 113433 is D2, and L2 and D2 satisfy: L2≤D2. When the second tooth portion 113422 is located below the second protrusion 113433, and there is relative movement between the gear 11342 and the drive rod 11343, the above-mentioned dimensional design can reduce the sliding friction between the second tooth portion 113422 and the drive surface 11343a of the drive rod 11343, thereby helping to reduce the wear of the gear 11342 and reduce the transmission resistance of the drive structure.

[0116] Referring to Figures 12a and 12b, in the state shown in Figure 12a, when the drive rod 11343 moves to the left until the second sub-rack 113436 meshes with the second tooth 113422 of the gear 11342, the gear 11342 rotates counterclockwise under the drive of the drive rod 11343, thereby driving the stud 11341 to move. For example, the counterclockwise rotation of the gear 11342 can drive the stud 11341 to move downwards, thereby causing the moving plate 1132 to move towards the fixed plate 1133, thus switching the control device 113 from the first state to the second state.

[0117] Referring to Figures 12b and 12c, in the state shown in Figure 12b, as the drive rod 11343 continues to move to the left, the second sub-rack 113436 transitions from meshing with the second tooth 113422 of the gear 11342 to meshing with the third tooth 113423 of the gear 11342, so as to continue driving the gear 11342 to rotate counterclockwise until the stud 11341 drives the moving plate 1132 to contact the fixed plate 1133, thus switching the control device 113 to the second state. After the control device 113 switches to the second state, the third protrusion 113434 of the drive rod 11343 engages with the first tangential wall 113424 of the gear 11342, and the first tooth 113421 of the gear 11342 is located above the third protrusion 113434. If the drive rod 11343 continues to move to the left, since there is no meshing relationship between the drive rod 11343 and the gear 11342, the gear 11342 will no longer rotate, and the control device 113 will remain in the second state.

[0118] Along the direction perpendicular to the first tangential wall 113424, the maximum length of each tooth in the first tooth portion 113421 extending beyond the first tangential wall 113424 is L1 (refer to Figure 12a). Along the direction perpendicular to the drive surface 11343a, the thickness of the third convex strip 113434 is D3, and L1 and D3 satisfy: L1≤D3. When the first tooth portion 113421 is located above the third convex strip 113434, and there is relative movement between the gear 11342 and the drive rod 11343, the above-mentioned dimensional design can reduce the sliding friction between the teeth of the first tooth portion 113421 and the drive surface 11343a of the drive rod 11343, thereby helping to reduce the wear of the gear 11342 and reduce the transmission resistance of the drive structure.

[0119] Referring to Figures 12c and 12d, in the state shown in Figure 12c, when the drive rod 11343 moves to the right, since the height of the first tooth 113421 of the gear 11342 is higher than the height of the second protrusion 113433 of the drive rod 11343, and the height of the second protrusion 113433 of the drive rod 11343 is higher than the height of its second sub-rack 113436, the first tooth 113421 of the gear 11342 is located above the second sub-rack 113436 of the drive rod 11343. The first tangential wall 113424 of the gear 11342 abuts against the second sub-rack 113436 of the drive rod 11343. There is no meshing relationship between the gear 11342 and the drive rod 11343, and the gear 11342 does not rotate. The control device 113 continues to remain in the second state.

[0120] Referring to Figures 12d and 12e, in the state shown in Figure 12d, the drive rod 11343 continues to move to the right. The second protrusion 113433 of the drive rod 11343 is in contact with the first tangential wall 113424 of the gear 11342. The first tooth 113421 of the gear 11342 is located above the second protrusion 113433. Therefore, there is still no meshing relationship between the gear 11342 and the drive rod 11343, and the gear 11342 does not rotate.

[0121] The maximum value L1 of the length of each tooth in the first tooth portion 113421 extending beyond the first tangential wall 113424 satisfies L1 ≤ D2 with the thickness D2 of the second convex strip 113433 (refer to Figure 12a). When the first tooth portion 113421 is located above the second convex strip 113433 and there is relative movement between the gear 11342 and the drive rod 11343, the above-mentioned dimensional design can reduce the sliding friction between the teeth of the first tooth portion 113421 and the driving surface 11343a of the drive rod 11343, thereby helping to reduce the wear of the gear 11342 and reduce the transmission resistance of the drive structure.

[0122] Referring to Figures 12e and 12f, in the state shown in Figure 12e, the drive rod 11343 continues to move to the right. When the drive rod 11343 moves to the point where the first sub-rack 113435 meshes with the first tooth 113421 of the gear 11342, the gear 11342 rotates clockwise under the drive of the drive rod 11343, thereby driving the stud 11341 to move. For example, the clockwise rotation of the gear 11342 can drive the stud 11341 to move upward, thereby causing the moving plate 1132 to move away from the fixed plate 1133, thus switching the control device 113 from the second state to the first state.

[0123] Referring to Figures 12f and 12g, in the state shown in Figure 12f, as the drive rod 11343 continues to move to the right, the first sub-rack 113435 transitions from meshing with the second tooth 113422 of the gear 11342 to meshing with the third tooth 113423 of the gear 11342, so as to continue driving the gear 11342 to rotate clockwise until the stud 11341 drives the moving plate 1132 to contact the fixed plate 1133, thus switching the control device 113 to the first state. After the control device 113 switches to the first state, the first protrusion 113432 of the drive rod 11343 engages with the second tangential wall 113425 of the gear 11342. The second tooth 113422 of the gear 11342 is located below the first protrusion 113432. If the drive rod 11343 continues to move to the right, since there is no meshing relationship between the drive rod 11343 and the gear 11342, the gear 11342 will no longer rotate, and the control device 113 will remain in the first state.

[0124] Along the direction perpendicular to the drive surface 11343a, the thickness of the first protrusion 113432 is D1. D1 and the maximum value of the lengths of each tooth in the second tooth portion 113422 extending beyond the second tangential wall 113425, L2 (refer to Figure 12c), satisfy the following condition: L2 ≤ D1. When the second tooth portion 113422 is located below the first protrusion 113432 and there is relative movement between the gear 11342 and the drive rod 11343, the above-mentioned dimensional design can reduce the sliding friction between the teeth of the second tooth portion 113422 and the drive surface 11343a of the drive rod 11343, thereby helping to reduce the wear of the gear 11342 and reduce the transmission resistance of the drive structure.

[0125] Referring to Figures 12g and 12h, in the state shown in Figure 12g, when the drive rod 11343 moves to the left, the height of the second tooth 113422 of the gear 11342 is lower than the height of the second protrusion 113433 of the drive rod 11343, and the height of the second protrusion 113433 of the drive rod 11343 is lower than the height of its first sub-rack 113435. Therefore, the second tooth 113422 of the gear 11342 is located below the first sub-rack 113435 of the drive rod 11343. The second tangential wall 113425 of the gear 11342 abuts against the first sub-rack 113435 of the drive rod 11343. There is no meshing relationship between the gear 11342 and the drive rod 11343, and the gear 11342 does not rotate. When the drive rod 11343 continues to move to the left, it returns to the state shown in Figure 12a.

[0126] Figure 13 is a schematic diagram of the travel of the drive rod 11343 shown in Figure 10a. Referring to Figures 12a to 12h and Figure 13, the analysis of the driving process of the drive structure above shows that the travel of the drive rod 11343 in both directions can be divided into three stages. In the travel of the drive rod 11343 to the left, from right to left, the stages are A1, A2, and A3. In the travel of the drive rod 11343 to the right, from left to right, the stages are B1, B2, and B3.

[0127] In this diagram, stage A1 is shown in Figure 12h, stage A2 is shown in Figure 12a, and stage A3 is shown in Figure 12b. In stages A1 and A2, the drive rod 11343 and gear 11342 are not meshed. In stage A3, the drive rod 11343 drives the gear 11342 to rotate counterclockwise, switching the control device from the first state to the second state. That is, during the initial stroke of the drive rod 11343 moving to the left, the control device is locked in the first state; during the final stroke of the drive rod 11343 moving to the left, the control device is switched from the first state to the second state.

[0128] The fourth stage B1 is shown in Figure 12d, the fifth stage B2 is shown in Figure 12e, and the sixth stage B3 is shown in Figure 12f. In the fourth stage B1 and the fifth stage B2, the drive rod 11343 and the gear 11342 are not meshed. In the sixth stage B3, the drive rod 11343 drives the gear 11342 to rotate clockwise, switching the control device from the second state to the first state. That is, during the first part of the stroke of the drive rod 11343 moving to the right, the control device is locked in the second state, and during the last part of the stroke of the drive rod 11343 moving to the right, the control device is switched from the second state to the first state.

[0129] As can be seen, the drive structure provided in this embodiment can reliably drive the control device to switch back and forth between the first and second states, and can also lock the control device in the first or second state by disengaging the drive rod 11343 from the gear 11342, effectively improving the operational reliability of the control device. Furthermore, when the drive rod 11343 and gear 11342 are not engaged, since the movement of the drive rod 11343 does not affect the state of the control device, the travel distance of the drive rod 11343 can also be used to achieve other functions. In other words, during the first stage A1 and / or the second stage A2 of the drive rod 11343 moving to the left, and the fourth stage B1 and / or the fifth stage B2 of the drive rod 11343 moving to the right, the drive rod 11343 can also serve as a drive for other components in the power supply network, driving them to achieve corresponding functions. This simplifies the structure of the power supply network, reduces its layout space, and can reduce the cost of the power supply network to a certain extent.

[0130] For example, in some embodiments, the drive rod 11343 can also serve as a drive element for the phase shifter, driving the phase shifter to perform the phase shifting function. In this way, the phase shifter and the control device can share the same drive element. Exemplarily, in the second stage of the stroke of the drive rod 11343 moving to the left, the drive rod 11343 can drive the phase shifter to switch from an operating state to a non-operating state; in the fifth stage of the stroke of the drive rod 11343 moving to the right, the drive rod 11343 can drive the phase shifter to switch from a non-operating state to an operating state.

[0131] Figure 14a is a schematic diagram of another drive rod 11343 provided in an embodiment of this application, and Figure 14b is a plan view of the drive rod 11343 shown in Figure 14a. Referring to Figures 14a and 14b together, in this embodiment of the application, the drive rod 11343 has a drive surface 11343a, which is arranged along a first direction. The drive surface 11343a is provided with a first protrusion 113432 and a second protrusion 113433, which are spaced apart along the length direction of the drive rod 11343. A rack 113431 is disposed on the drive surface 11343a. Along the length direction of the drive rod 11343, the rack 113431 is located between the first boss 113426 and the second protrusion 113433. Along a first direction, at least a portion of the height of the rack 113431 is lower than the height of the first protrusion 113432, and at least a portion of the height of the rack 113431 is lower than the height of the second protrusion 113433. That is, the rack 113431 can be entirely lower than the height of the first protrusion 113432 and the second protrusion 113433, or it can be partially lower than the height of the first protrusion 113432 and the second protrusion 113433. For example, the first protrusion 113432 and the second protrusion 113433 are respectively disposed near the top surface of the drive rod 11343 along the height direction, and the rack 113431 is disposed near the bottom surface of the drive rod 11343 along the height direction.

[0132] Figure 15 is a schematic diagram of another gear 11342 provided in an embodiment of this application. Referring to Figure 15, in this embodiment, the gear 11342 includes a first end face 11342a and a second end face 11342b disposed opposite to each other along a first direction. The gear 11342 includes a first tooth portion 113421, a second tooth portion 113422, a third tooth portion 113423, a first tangential wall 113424, and a second tangential wall 113425. The first tooth portion 113421 and the first tangential wall 113424 are arranged along the first direction. The first tooth portion 113421 is disposed near the second end face 11342b, and the first tangential wall 113424 is disposed near the first end face 11342a. Along the radial direction of the gear 11342, each tooth in the first tooth portion 113421 extends at least partially beyond the first tangential wall 113424. The second tooth portion 113422 and the second tangential wall 113425 are arranged along a first direction. The second tooth portion 113422 is disposed near the second end face 11342b, and the second tangential wall 113425 is disposed near the first end face 11342a. Along the radial direction of the gear 11342, at least a portion of each tooth in the second tooth portion 113422 extends beyond the second tangential wall 113425. Along the circumferential direction of the gear 11342, the third tooth portion 113423 connects the first tooth portion 113421 and the second tooth portion 113422. The teeth of the third tooth portion 113423 can extend from the first end face 11342a to the second end face 11342b.

[0133] Similarly, in this embodiment, the first end face 11342a and the second end face 11342b of the gear 11342 may be provided with bosses 113426 respectively, so as to reduce the friction between the gear teeth of the gear 11342 and the limiting wall and the top wall during the rotation of the gear 11342, and improve the structural reliability of the gear 11342.

[0134] In addition, the positions of the first tangential wall 113424 and the second tangential wall 113425 on the periphery of the gear 11342 can also be designed according to the requirements of the rotation stroke of the gear 11342. For example, in the embodiment shown in Figure 15, the angle between the normal of the first tangential wall 113424 and the normal of the second tangential wall 113425 is approximately 180°.

[0135] Figures 16a to 16p are schematic diagrams of the transmission connection between the drive rod 11343 shown in Figure 14a and the gear 11342 shown in Figure 15 under different states. Among them, Figures 16a and 16b, Figures 16c and 16d, Figures 16e and 16f, Figures 16g and 16h, Figures 16i and 16j, Figures 16k and 16l, Figures 16m and 16n, and Figures 16n and 16p are assembly diagrams of the drive rod 11343 and the gear 11342 from different perspectives under the same transmission state. Referring to Figures 16a to 16p, in this embodiment, the first tooth 113421, the second tooth 113422, and the third tooth 113423 can respectively mesh with the rack 113431. The height of the first tooth 113421 is lower than the height of the first protrusion 113432, and the height of the second tooth 113422 is lower than the height of the second protrusion 113433. The first tangential wall 113424 can fit against the first protrusion 113432, and the second tangential wall 113425 can fit against the second protrusion 113433. The driving process of the driving structure in this embodiment will be described below with reference to the two states of the control device 113 shown in Figures 8a and 8b.

[0136] Referring first to Figures 16a and 16b, in this transmission state, the second tangential wall 113425 of the gear 11342 is in contact with the second protrusion 113433 of the drive rod 11343, and the second tooth 113422 of the gear 11342 is located below the second protrusion 113433 of the drive rod 11343 (view from Figure 16a). When the drive rod 11343 moves to the left or right, since there is no meshing relationship between the drive rod 11343 and the gear 11342, the gear 11342 does not rotate, and the stud 11341 naturally does not move, and the state of the control device 113 remains unchanged. Exemplarily, in the transmission state shown in Figures 16a and 16b, the control device 113 remains in the second state.

[0137] Along the direction perpendicular to the second tangential wall 113425, the maximum length of each tooth in the second tooth portion 113422 extending beyond the second tangential wall 113425 is L2'. Along the direction perpendicular to the drive surface 11343a, the thickness of the second convex strip 113433 is D2', and L2' and D2' satisfy: L2'≤D2'. When the second tooth portion 113422 is located below the second convex strip 113433, and there is relative movement between the gear 11342 and the drive rod 11343, the above-mentioned dimensional design can reduce the sliding friction between the second tooth portion 113422 and the drive surface 11343a of the drive rod 11343, thereby helping to reduce the wear of the gear 11342 and reduce the transmission resistance of the drive structure.

[0138] Referring to Figures 16a, 16b, 16c, and 16d, in the states shown in Figures 16a and 16b, when the drive rod 11343 moves to the right until the rack 113431 meshes with the second tooth 113422 of the gear 11342, the gear 11342 rotates clockwise under the drive of the drive rod 11343 (view from Figure 16c), thereby driving the stud 11341 to move. For example, the clockwise rotation of the gear 11342 can drive the stud 11341 to move upwards, thereby causing the moving plate 1132 to move away from the fixed plate 1133, thus switching the control device 113 from the second state to the first state.

[0139] Referring also to Figures 16c, 16d, 16e, and 16f, in the states shown in Figures 16a and 16b, as the drive rod 11343 continues to move to the right, the rack 113431 transitions from meshing with the second tooth 113422 of the gear 11342 to meshing with the third tooth 113423 of the gear 11342, so as to continue driving the gear 11342 to rotate clockwise (view from Figure 16e).

[0140] Referring to Figures 16e, 16f, 16g, and 16h, in the states shown in Figures 16e and 16f, the drive rod 11343 continues to drive the gear 11342 to rotate clockwise until the stud 11341 completely separates the moving plate 1132 from the fixed plate 1133, switching the control device 113 to the first state. After switching the control device 113 to the first state, the first protrusion 113432 of the drive rod 11343 engages with the first tangential wall 113424 of the gear 11342, and the first tooth 113421 of the gear 11342 is located below the first protrusion 113432 of the drive rod 11343 (view from Figure 16g). If the drive rod 11343 continues to move to the right, since there is no meshing relationship between the drive rod 11343 and the gear 11342, the gear 11342 will no longer rotate, and the control device 113 will remain in the first state.

[0141] Along the direction perpendicular to the first tangential wall 113424, the maximum length of each tooth in the first tooth portion 113421 extending beyond the first tangential wall 113424 is L1'. Along the direction perpendicular to the driving surface 11343a, the thickness of the first protrusion 113432 is D1', and L1' and D1' satisfy: L1'≤D1'. When the first tooth portion 113421 is located below the first protrusion 113432, and there is relative movement between the gear 11342 and the drive rod 11343, the above-mentioned dimensional design can reduce the sliding friction between the first tooth portion 113421 and the driving surface 11343a of the drive rod 11343, thereby helping to reduce the wear of the gear 11342 and reduce the transmission resistance of the drive structure.

[0142] Referring to Figures 16g, 16h, 16i, and 16j, in the states shown in Figures 16g and 16h, when the drive rod 11343 begins to move to the left, the rack 113431 has not yet engaged with the gear 11342, so the gear 11342 does not rotate, and the control device 113 continues to remain in the first state.

[0143] Referring to Figures 16i, 16j, 16k, and 16l, when the drive rod 11343 continues to move to the left and reaches a certain position, the rack 113431 of the drive rod 11343 meshes with the first tooth 113421 of the gear 11342. Under the driving action of the drive rod 11343, the gear 11342 rotates counterclockwise (view from Figure 16k), thereby driving the stud 11341 to move. For example, the counterclockwise rotation of the gear 11342 can drive downward movement, thereby causing the moving plate 1132 to move towards the fixed plate 1133, thus switching the control device 113 from the first state to the second state.

[0144] Referring to Figures 16k, 16l, 16m, and 16n, in the states shown in Figures 16i and 16j, as the drive rod 11343 continues to move to the left, the rack 113431 transitions from meshing with the first tooth 113421 of the gear 11342 to meshing with the third tooth 113423 of the gear 11342, so as to continue driving the gear 11342 to rotate counterclockwise.

[0145] Referring to Figures 16m, 16n, 16n, and 16p, in the states shown in Figures 16i and 16j, the drive rod 11343 continues to move to the left until the stud 11341 drives the moving plate 1132 to contact the fixed plate 1133, switching the control device 113 to the second state. After switching the control device 113 to the second state, the second protrusion 113433 of the drive rod 11343 engages with the second tangential wall 113425 of the gear 11342, and the second tooth 113422 of the gear 11342 is located below the second protrusion 113433 of the drive rod 11343 (view from Figure 16n). If the drive rod 11343 continues to move to the left, since there is no meshing relationship between the drive rod 11343 and the gear 11342, the gear 11342 will no longer rotate, and the control device 113 will remain in the second state.

[0146] Figure 17 is a schematic diagram of the travel stroke of the drive rod 11343 shown in Figure 14a. Referring to Figures 16a to 16p and Figure 17, the analysis of the driving process of the drive structure above shows that the travel of the drive rod 11343 in both directions can be divided into three stages. In the travel stroke of the drive rod 11343 to the right, from left to right, the stages are A1, A2, and A3 respectively. In the travel stroke of the drive rod 11343 to the left, from right to left, the stages are B1, B2, and B3 respectively.

[0147] The three stages are as follows: the first stage A1 is shown in Figures 16a and 16b; the second stage A2 is shown in Figures 16c, 16d, 16e, and 16f; and the third stage A3 is shown in Figures 16g and 16h. It can be seen that in the first stage A1 and the third stage A3, the drive rod 11343 and the gear 11342 are not meshed. In the second stage A2, the drive rod 11343 drives the gear 11342 to rotate clockwise, switching the control device 113 from the second state to the first state. That is, during the initial stroke of the drive rod 11343 moving to the right, the control device 113 is locked in the second state; during the middle stroke of the drive rod 11343 moving to the right, the control device 113 is switched from the second state to the first state; and during the final stroke of the drive rod 11343 moving to the right, the control device 113 is locked in the first state.

[0148] The fourth stage B1 is shown in Figures 16i and 16j; the fifth stage B2 is shown in Figures 16k, 16l, 16m, and 16n; and the sixth stage B3 is shown in Figures 16n and 16p. It can be seen that in the fourth stage B1 and the sixth stage B3, the drive rod 11343 and gear 11342 are not meshed. In the fifth stage B2, the drive rod 11343 drives the gear 11342 to rotate counterclockwise, switching the control device 113 from the first state to the second state. That is, during the initial stroke of the drive rod 11343 moving to the left, the control device 113 is locked in the first state; during the middle stroke of the drive rod 11343 moving to the left, the control device 113 is switched from the first state to the second state; and during the final stroke of the drive rod 11343 moving to the left, the control device 113 is locked in the second state.

[0149] As can be seen, the driving structure provided in this embodiment can reliably drive the control device 113 to switch back and forth between the first state and the second state, and can also lock the control device 113 in the first state or the second state by disengaging the drive rod from the gear 11342, which effectively improves the working reliability of the control device 113.

[0150] Furthermore, similar to the aforementioned embodiments, when the drive rod 11343 and gear 11342 are not meshed, the movement stroke of the drive rod 11343 can also achieve phase shifting functionality by driving a phase shifter. For example, in the first or third stage of the movement of the drive rod 11343 to the right, the drive rod 11343 can drive the phase shifter to switch from a non-working state to a working state; in the fourth or sixth stage of the movement of the drive rod 11343 to the left, the drive rod 11343 can drive the phase shifter to switch from a working state to a non-working state.

[0151] Figure 18 is a schematic diagram showing the relative positional relationship between the fixed plate 1133 and the movable plate 1132 provided in an embodiment of this application. Referring to Figure 18, in this embodiment, the fixed plate 1133 is fixed to the housing 114 of the power supply network, and the transmission conductor 11331 has one input terminal and two output terminals, with the two output terminals respectively connected to one or more power supply output terminals of the power supply network. Exemplarily, one input terminal and two output terminals of the transmission conductor 11331 are respectively disposed near the side edge of the fixed plate 1133 for connection with the housing 114, so as to be connected to the feed line of the power supply network through conductive elements.

[0152] Figure 19a is a structural schematic diagram of the movable plate 1132 shown in Figure 18, Figure 19b is a structural schematic diagram of the fixed plate 1133 shown in Figure 18, and Figure 19c is a schematic diagram of the relative positional relationship between the adjustment control 11321 of the movable plate 1132 shown in Figure 19a and the transmission conductor 11331 of the fixed plate 1133 shown in Figure 19b. Referring to Figures 19a to 19c, in this embodiment, the transmission conductor 11331 and the control unit 11321 are both wires. The transmission conductor 11331 includes a first sub-transmission conductor 113311, a second sub-transmission conductor 113312, and a third sub-transmission conductor 113313. One end of the first sub-transmission conductor 113311 is the input terminal a of the transmission conductor 11331. One end of the second sub-transmission conductor 113312 is the first output terminal b1 of the transmission conductor 11331. The other end of the second sub-transmission conductor 113312 is connected to the other end of the first sub-transmission conductor 113311. One end of the third sub-transmission conductor 113313 is the second output terminal b2 of the transmission conductor 11331. The other end of the third sub-transmission conductor 113313 is spaced apart from the other end of the first sub-transmission conductor 113311. The orthographic projection of the third sub-transmission conductor 113313 in the first direction is connected to the orthographic projection of the adjustment control 11321 in the first direction, or at least part of their projections overlap. The orthographic projection of the first sub-transmission conductor 113311 in the first direction is connected to the orthographic projection of the adjustment control 11321 in the first direction, or at least part of their projections overlap.

[0153] Based on the design of the transmission conductor 11331 and the modulation control 11321, when the modulation device is in the first state, the input terminal a of the transmission conductor 11331 is connected to the first output terminal b1, and the input terminal a of the transmission conductor 11331 is disconnected from the second output terminal b2. When the modulation device is in the second state, the output terminal of the transmission conductor 11331 is connected to its first output terminal b1 and its second output terminal b2, respectively. Therefore, when the modulation device switches states, it can change the on / off state of the feeder between the RF input terminal a and the RF output terminal connected to the second output terminal b2 of the feed network, thereby changing the operating state of the radiating unit corresponding to the RF output terminal connected to the second output terminal b2.

[0154] In some embodiments, the modulation control 11321 includes a first sub-modulation control 113211 and a second sub-modulation control 113212. The orthographic projection of the first sub-transmission conductor 113311 in a first direction is connected to or at least partially overlaps with the orthographic projection of the first sub-modulation control 113211 in the first direction, and the orthographic projection of the third sub-transmission conductor 113313 in the first direction is connected to or at least partially overlaps with the orthographic projection of the first sub-modulation control 113211 in the first direction. Then, the first sub-modulation control 113211 is used to connect the first sub-transmission conductor 113311 and the third sub-transmission conductor 113313, so as to change the working state of the radiation unit corresponding to the radio frequency output terminal connected to the second output terminal b2 by turning the input terminal a on or off. The orthographic projection of the second sub-transmission conductor 113312 in the first direction at least partially coincides with the orthographic projection of the second sub-tuning control 113212 in the first direction. When the control device is in the second state, the second sub-tuning control 113212 is at least partially attached to the second sub-transmission conductor 113312, allowing the second sub-tuning control 113212 to control the transmission parameters (e.g., power division ratio) of the second sub-transmission conductor 113312. Based on this control effect, the electromagnetic wave amplitude of the radiating element corresponding to the RF output terminal connected to the first output terminal b1 will change. Therefore, in this embodiment, the control device can adjust both the number of radiating elements operating in the antenna and the electromagnetic wave amplitude of some of these radiating elements, thus effectively improving the functionality of the control device.

[0155] Figure 20 is a schematic diagram showing the relative positional relationship between the transmission conductor 11331 and the modulation control 11321 provided in another embodiment of this application. Referring to Figure 20, in this embodiment of the application, the transmission conductor 11331 and the modulation control 11321 are also wires. The transmission conductor 11331 has an input terminal a and an output terminal b, and the output terminal b is used to connect to one or more power supply output terminals of the power supply network. The transmission conductor 11331 includes a first sub-transmission conductor 113311 and a second sub-transmission conductor 113312. One end of the first sub-transmission conductor 113311 is the input terminal a of the transmission conductor 11331, and one end of the second sub-transmission conductor 113312 is the output terminal b of the transmission conductor 11331. The other ends of the first sub-transmission conductor 113311 and the other ends of the second sub-transmission conductor 113312 are spaced apart. The orthographic projection of the first sub-transmission conductor 113311 in the first direction is connected to the orthographic projection of the adjustment control 11321 in the first direction, or at least partially overlaps the projections of the two. The orthographic projection of the second sub-transmission conductor 113312 in the first direction is connected to the orthographic projection of the adjustment control 11321 in the first direction, or at least partially overlaps the projections of the two.

[0156] Based on the design of the transmission conductor 11331 and the modulation control 11321, when the modulation device is in the first state, the input terminal a of the transmission conductor 11331 is disconnected from its output terminal b; when the modulation device is in the second state, the input terminal of the transmission conductor 11331 is connected to its output terminal. Therefore, when the modulation device switches states, it can change the continuity state of the feed line between the RF input terminal of the feed network and the RF output terminal connected to the output terminal b of the transmission conductor 11331, thereby changing the operating state of the radiation unit corresponding to the RF output terminal connected to the output terminal b of the transmission conductor 11331.

[0157] Figure 21 is a schematic diagram showing the relative positional relationship between the transmission conductor 11331 and the modulation control 11321 according to another embodiment of this application. Referring to Figure 21, in this embodiment, the transmission conductor 11331 is a strip wire, and the modulation control 11321 can be either a strip wire or a dielectric block. The transmission conductor 11331 is a continuous integral structure, having an input terminal a and an output terminal b, whereby the output terminal b is used to connect to one or more feed output terminals of the feed network. The orthographic projection of the transmission conductor 11331 in the first direction at least partially coincides with the orthographic projection of the modulation control 11321 in the first direction.

[0158] Based on the design of the transmission conductor 11331 and the control device 11321, when the control device is in the first state, the input terminal a of the transmission conductor 11331 is connected to its output terminal b, and the control device 11321 has no control effect on the transmission conductor 11331. When the control device is in the second state, the input terminal a of the transmission conductor 11331 is also connected to its output terminal b, and at least part of the control device 11321 is attached to the transmission conductor 11331. Therefore, the control device 11321 can control the transmission parameters of the transmission conductor 11331.

[0159] When the modulation control 11321 is a strip, the electromagnetic wave amplitude of the radiating unit corresponding to the radio frequency output terminal connected to the second output terminal b2 of the transmission conductor 11331 can be changed by the modulation function of the modulation control 11321; when the modulation control 11321 is a dielectric block, the electromagnetic wave phase of the radiating unit corresponding to the radio frequency output terminal connected to the second output terminal b2 of the transmission conductor 11331 can be changed by the modulation function of the modulation control 11321.

[0160] Figure 22 is a schematic diagram showing the relative positional relationship between the transmission conductor 11331 and the modulation control 11321 according to another embodiment of this application. Referring to Figure 22, in this embodiment of the application, the transmission conductor 11331 is a strip wire, and the modulation control 11321 can be either a strip wire or a dielectric block. The transmission conductor 11331 has one input terminal a and two output terminals, and the two output terminals are respectively connected to one or more feed output terminals of the feed network. The transmission conductor 11331 includes a first sub-transmission conductor 113311, a second sub-transmission conductor 113312, and a third sub-transmission conductor 113313. One end of the first sub-transmission conductor 113311 is the input terminal a of the transmission conductor 11331; one end of the second sub-transmission conductor 113312 is the first output terminal b1 of the transmission conductor 11331; and one end of the third sub-transmission conductor 113313 is the second output terminal b2 of the transmission conductor 11331. The other ends of the first sub-transmission conductor 113311, the second sub-transmission conductor 113312, and the third sub-transmission conductor 113313 are interconnected. The orthographic projection of the third sub-transmission conductor 113313 in the first direction at least partially coincides with the orthographic projection of the adjustment control 11321 in the first direction.

[0161] Based on the design of the transmission conductor 11331 and the control device 11321, when the control device is in the first state, the input terminal a of the transmission conductor 11331 is connected to the first output terminal b1 and the second output terminal b2 respectively, and the control device 11321 has no control effect on the transmission conductor 11331. When the control device is in the second state, the input terminal of the transmission conductor 11331 is connected to its output terminal and the second transmission conductor 11331 respectively, and at least part of the control device 11321 is attached to the third sub-transmission conductor 113313. Therefore, the control device 11321 can control the transmission parameters of the third sub-transmission conductor 113313.

[0162] When the modulation control 11321 is a strip, the electromagnetic wave amplitude of the radiating unit corresponding to the radio frequency output terminal connected to the second output terminal b2 of the transmission conductor 11331 can be changed by the modulation function of the modulation control 11321; when the modulation control 11321 is a dielectric block, the electromagnetic wave phase of the radiating unit corresponding to the radio frequency output terminal connected to the second output terminal b2 of the transmission conductor 11331 can be changed by the modulation function of the modulation control 11321.

[0163] The above embodiments only exemplify several structural designs of the transmission conductor 11331 and the control device 11321. In other embodiments, the transmission conductor 11331 and the control device 11321 can also adopt other design forms, as long as the control device 11321 can achieve the control function of the transmission conductor 11331 when the control device is in the second state. These will not be elaborated on here.

[0164] Figure 23 is a schematic diagram of another installation structure of the control device 113 provided in an embodiment of this application. Referring to Figure 23, in this embodiment of the application, multiple control devices 113 can be set in the power supply network. Taking two control devices 113 as an example, the two control devices 113 share a drive rod 11343. When the drive rod 11343 moves to one side, it can synchronously drive the two control devices 113 to switch from the second state to the first state. When the drive rod 11343 moves to the other side, it can synchronously drive the two control devices 113 to switch from the first state to the second state. Based on the design that the states of multiple control devices 113 can be switched synchronously by the drive rod 11343, the multiple control devices 113 can be regarded as being set in parallel.

[0165] The synchronous switching of states between the two control devices 113 driven by the drive rod 11343 can be achieved through a segmented design. For example, the drive rod 11343 includes a first structural segment and a second structural segment arranged along its length. The first and second structural segments can respectively adopt the design of three protruding strips and two racks as shown in Figure 10a. Correspondingly, the gears of each control device 113 can respectively adopt the structural form shown in Figure 11a; or, the first and second structural segments can respectively adopt the design of two protruding strips and one rack as shown in Figure 14a. Correspondingly, the gears of each control device 113 respectively adopt the structural form shown in Figure 15. By reasonably setting the relative positional relationship between the first structural segment and the corresponding gear, and the relative positional relationship between the second structural segment and the corresponding gear, the first and second structural segments can drive the two control devices 113 to switch states synchronously.

[0166] The driving stroke of drive lever 11343 can be referred to the relevant descriptions in Figure 13 or Figure 17, and will not be repeated here.

[0167] It should be noted that Figure 23 only illustrates the case where there are two control devices 113 in the power supply network. In other embodiments, there may be three or more control devices 113. Accordingly, the drive rod 11343 is designed as three or more structural segments to drive each control device 113 to switch states synchronously.

[0168] Figure 24a is a beam diagram of an antenna 100 in a first state when the control device 113 is in a first state according to an embodiment of this application, and Figure 24b is a beam diagram of an antenna 100 in a second state when the control device 113 is in a second state according to an embodiment of this application. Referring to Figures 24a and 24b together, in this embodiment of the application, the feed network 110 of the antenna 100 is provided with a phase shifter 112 and two control devices 113. The phase shifter 112 is disposed at the RF input terminal of the feed network 110, and the two control devices 113 are respectively disposed at the input terminals of two sub-branches. In a specific implementation, the phase shifter 112 and the two control devices 113 can be driven by the same drive rod 11343. In one phase of moving to one side, the drive rod 11343 is used to drive the phase shifter 112 to switch from a non-working state to a working state. In another phase of moving to one side, the drive rod 11343 is used to drive the two control devices 113 to switch from a second state to a first state simultaneously. Conversely, in one phase of moving to the other side, the drive rod 11343 is used to drive the two control devices 113 to switch from a first state to a second state simultaneously. In another phase of moving to the other side, the drive rod 11343 is used to drive the phase shifter 112 to switch from a working state to a non-working state.

[0169] In one implementation, the transmission conductor and control unit of the control device 113 can respectively adopt the design forms shown in Figure 20. The input end of the transmission conductor of the control device 113 is connected to the input end of the sub-branch 11111, and the output end of the transmission conductor is connected to the two output ends of the sub-branch 11111. The control device 113 is used to control the working state of the two radiation units 120 connected to the two output ends of the sub-branch 11111.

[0170] As can be seen from Figures 24a and 24b, when both control devices 113 are in the second state, the number of working radiating elements 120 in the antenna 100 is large, the beamwidth of the antenna 100 is small (manifested as a smaller β1 angle), the beam energy is concentrated, and the beam radiation distance is relatively long. When both control devices 113 are in the first state, the number of working radiating elements 120 in the antenna 100 is small, the beamwidth of the antenna 100 is large (manifested as a larger β2 angle), and the beam radiation distance is relatively short.

[0171] Figure 25 shows the phase shifting effect of phase shifter 112 in the working state in Figures 24a and 24b. Referring to Figure 25, phase shifter 112 can adjust the phase of all radiating elements 120 of antenna 100 in the working state, causing the antenna's vertical beam to shift downwards, thus adjusting the electrical downtilt angle of antenna 100 to α. Here, the electrical downtilt angle refers to the phase difference between adjacent radiating elements 120 in antenna 100. At that time, the angle between the maximum radiation direction of antenna 100 and the normal of antenna 100.

[0172] Figure 26 shows the beam superposition effect of the antenna 100 shown in Figures 24a and 24b under the combined action of the phase shifter 112 and the control device 113. Referring to Figure 26, when the phase shifter 112 is in the working state and both control devices 113 are in the second state, the antenna 100 can achieve dual-dimensional digital adjustment of the electrical downtilt angle α and the beamwidth β2, thereby optimizing the signal coverage effect of the antenna 100.

[0173] Figure 27 is a schematic diagram of another installation structure of the control device provided in an embodiment of this application. Referring to Figure 27, in this embodiment of the application, multiple control devices can also be set in the power supply network. Taking two control devices as an example, the two control devices are defined as the first control device 113a and the second control device 113b. The first control device 113a and the second control device 113b share a drive rod 11343. When the drive rod 11343 moves to one side, it can sequentially drive the first control device 113a and the second control device 113b to switch from a first state to a second state. When the drive rod 11343 moves to the other side, it can sequentially drive the two second control devices 113b and the first control device 113a to switch from the second state to the first state. Based on the design that the states of multiple first control devices 113a and second control devices 113b can be switched sequentially by the drive rod 11343, the first control devices 113a and the second control devices 113b can be regarded as being set in series.

[0174] In this embodiment, the sequential switching of the states of the first control device 113a and the second control device 113b by the drive rod 11343 can be achieved through a segmented design. For example, the drive rod 11343 includes a first structural segment and a second structural segment arranged along its length. The first structural segment and the second structural segment can respectively adopt the design of three protruding strips and two racks as shown in Figure 10a. Correspondingly, the gears of the first control device 113a and the second control device 113b can respectively adopt the structural form shown in Figure 11a; or, the first structural segment and the second structural segment can respectively adopt the design of two protruding strips and one rack as shown in Figure 14a. Correspondingly, the gears of the first control device 113a and the second control device 113b can respectively adopt the structural form shown in Figure 15. By reasonably setting the relative positional relationship between the first structural segment and the gear of the first control device 113a, and the relative positional relationship between the second structural segment and the gear of the second control device 113b, the first structural segment and the second structural segment can drive the first control device 113a and the second control device 113b to switch sequentially.

[0175] Taking the design of the first and second structural sections of the drive rod 11343, which respectively adopt the two protrusions and one rack shown in Figure 14a, as an example, the travel of the drive rod 11343 can be referred to Figure 28. The travel of the drive rod 11343 in the two directions of movement can be divided into three stages. In the travel of the drive rod 11343 to the right, from left to right, the stages are A1, A2, and A3. In the travel of the drive rod 11343 to the left, from right to left, the stages are B1, B2, and B3.

[0176] In the first stage A1, none of the structural segments of the drive rod 11343 mesh with the gears of the two control devices. In the second stage A2, the first structural segment drives the first control device 113a to switch from the second state to the first state. In the third stage A3, the second structural segment drives the second control device 113b to switch from the second state to the first state. In the fourth stage B1, the second structural segment of the drive rod 11343 drives the second control device 113b to switch from the first state to the second state. In the fifth stage B2, the first structural segment of the drive rod 11343 drives the first control device 113a to switch from the first state to the second state. In the sixth stage B3, none of the structural segments of the drive rod 11343 mesh with the corresponding gears.

[0177] Similarly, in the first stage A1 of the stroke of the drive lever 11343 moving to the left, the drive lever 11343 can be used to drive the phase shifter to switch from a non-working state to a working state; in the sixth stage B3 of the stroke of the drive lever 11343 moving to the left, the drive lever 11343 can drive the phase shifter to switch from a working state to a non-working state.

[0178] Figures 27 and 28 only illustrate one scenario of two control devices being connected in series. It should be understood that when there are three or more control devices, the drive rod 11343 can be designed accordingly as three or more structural segments, with each structural segment sequentially driving each control device to switch states.

[0179] Figures 29a to 29c show the beamform of another antenna 100 provided in this embodiment of the application with each control device 113 in different states. Referring also to Figures 29a to 29c, in this embodiment of the application, the feed network 110 of the antenna 100 is provided with a phase shifter 112 and two control devices. The phase shifter 112 is located at the RF input terminal of the feed network 110. One first control device 113a is located at the input terminal of a branch 1111, and the second control device 113b is located at the input terminal of a sub-branch 11111. The two first control devices 113a and the second control device 113b are connected in series. In the specific implementation, the phase shifter 112 and the two control devices are all driven by the same drive rod. Referring to the schematic diagram of the movement stroke of the drive rod 11343 shown in Figure 28, the drive rod 11343 moves to the right in the first stage A1 to drive the phase shifter 112 from the non-working state to the working state, in the second stage A2 to drive the first control device 113a from the second state to the first state, and in the third stage to drive the second control device 113b from the second state to the first state. Conversely, the drive rod moves to the left in the fourth stage B1 to drive the second control device 113b from the first state to the second state, in the fifth stage B2 to drive the first control device 113a from the first state to the second state, and in the sixth stage B3 to drive the phase shifter 112 from the working state to the non-working state.

[0180] In one implementation, the transmission conductors and control units of the first control device 113a and the second control device 113b can respectively adopt the design forms shown in FIG20. The input end of the transmission conductor of the first control device 113a is connected to the input end of the branch 1111, and the output end is connected to the input ends of the multiple sub-branches 11111 of the branch 1111 respectively. The first control device 113a is used to control the working state of the four radiation units 120 connected to the output ends of the multiple sub-branches 11111 in the branch 1111. The input end of the transmission conductor of the second control device 113b is connected to the input end of the sub-branch 11111, and the output end is connected to the two output ends of the sub-branch 11111. The second control device 113b is used to control the working state of the two radiation units 120 connected to the output ends of the sub-branch 11111.

[0181] Referring to Figure 29a, when both the first control device 113a and the second control device 113b are in the second state, the number of radiating elements 120 operating in the antenna 100 is large, the beamwidth of the antenna 100 is small (manifested as a smaller β1 angle), the beam energy is concentrated, and the beam radiation distance is relatively long. Referring to Figure 29b, when the first control device 113a is in the second state and the second control device 113b is in the first state, the number of radiating elements 120 operating in the antenna 100 is reduced, and the beamwidth of the antenna 100 is widened (β2 > β1). Referring to Figure 29c, when both the first control device 113a and the second control device 113b are in the first state, the number of radiating elements 120 operating in the antenna 100 is further reduced, and the beamwidth of the antenna 100 is further widened (β3 > β2).

[0182] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
