Antenna structure, communication base station and active antenna unit

[0001] This application claims priority to Chinese patent application filed on March 24, 2025, with application number 202510353347.2 and title "Antenna Structure, Communication Base Station and Active Antenna Element", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, specifically to an antenna structure, a communication base station, and an active antenna unit. Background Technology

[0003] A communication base station generally includes an antenna structure and a radio frequency (RF) device. The RF device is used to send signals to the antenna structure, enabling the antenna to transmit and receive signals from the outside world. The antenna structure includes a radiator, which is typically formed from a metal plate through a stamping process. This radiator has a relatively large mass, resulting in a large overall mass for the antenna structure. Summary of the Invention

[0004] This application provides an antenna structure, a communication base station, and an active antenna element, which can reduce the mass of the antenna structure.

[0005] In a first aspect, embodiments of this application provide an antenna structure, including: a first radiator, an antenna support, a reflector, and a feed element. The first radiator includes a conductive sheet; the antenna support is formed by folding a dielectric substrate around a preset center line, the first radiator is attached to the antenna support, and a feed line coupled to the first radiator is provided on the antenna support; the reflector is disposed on one side of the antenna support and is used to reflect signals to the first radiator; the feed element is disposed on the reflector and is coupled to the feed line.

[0006] With the above configuration, the antenna support is formed by folding a dielectric substrate around a preset center line. The first radiator includes a conductive sheet attached to the antenna support. A feed line coupled to the first radiator is provided on the antenna support. A reflector is disposed on one side of the antenna support and is used to reflect signals to the first radiator. A feed element is disposed on the reflector and coupled to the feed line to transmit signals to the first radiator. The first radiator, including the conductive sheet, is attached to the antenna support. The thickness of the first radiator can be set to be relatively small, thereby reducing the mass of the first radiator and the antenna structure.

[0007] On the other hand, the antenna support is formed by folding the dielectric substrate around a preset center, that is, the antenna support is a hollow support, which can further reduce the mass of the antenna structure; and the folded antenna support is easier to manufacture and assemble.

[0008] In some embodiments that may include the above examples, the dielectric board includes at least one of a foamed board, a resin board, and a rubber board. The foamed board can be a sheet made of a foamed material, which can be a substrate with a bubble structure formed within the substrate by physical or chemical means. Because of its bubble structure, the foamed board has a dielectric constant closer to that of air, thus reducing dielectric loss.

[0009] In some embodiments that may include the above-described examples, a groove is provided at the crease of the dielectric substrate, and the length direction of the groove is parallel to the crease. That is, the dielectric substrate bends at the groove. This design facilitates the bending of the dielectric substrate and allows control over the folding position, thereby improving the shape and dimensional accuracy of the antenna support.

[0010] Understandably, grooves can be formed through cutting, extrusion, or other methods to facilitate their formation on the substrate. The cross-section of the groove can be rectangular, triangular, approximately semi-circular, approximately elliptical, or other regular shapes. Of course, the cross-section of the groove can also be other irregular shapes.

[0011] In some embodiments that may include the above-described examples, the cross-section of the antenna support perpendicular to the preset center line is at least one of trapezoidal, rectangular, or triangular. The regular cross-sectional shape of the antenna support reduces the difficulty of bending the dielectric substrate and thus reduces the difficulty of fabricating and installing the antenna structure.

[0012] In some embodiments that may include the above-described examples, the antenna support includes a fixing plate, which is attached to the reflector and connected to it. This configuration allows for fixation between the antenna support and the reflector via the fixing plate, improving the structural compactness of the antenna structure.

[0013] In some embodiments that may include the above-described embodiments, the feed line extends to the fixed plate, and the feed line on the fixed plate is coupled to the feed component. Since the feed component is located on the reflector plate, and the fixed plate is attached to the reflector plate, the connection between the feed line and the feed component is facilitated by coupling a portion of the feed line on the fixed plate to the feed component.

[0014] In some embodiments that may include the above-described examples, a first through-hole is provided on the reflector. The power supply component includes an insulating block and a conductive component. The insulating block is disposed within the first through-hole, and the conductive component passes through the insulating block. One end of the conductive component contacts the power supply line, and the other end of the conductive component is used to receive radio frequency signals. This configuration achieves coupling between the power supply component and the power supply line through the contact between the conductive component and the power supply line. The structure is simple, the connection is reliable, and it is easy to install and disassemble.

[0015] In some embodiments that may include the above-described examples, the antenna structure further includes a crimping member connected to the reflector, with a fixing plate sandwiched between the crimping member and the reflector. This configuration allows the fixing plate to be securely fixed to the reflector via the crimping member, resulting in a reliable connection and a simple structure. It is understood that while the crimping member presses the fixing plate onto the reflector, it also ensures good contact between the conductive components and the feed line.

[0016] In some embodiments that may include the above-described embodiments, a recess may be provided on the fixing plate, and a pressing member may be disposed in the recess. The recess may restrict the position of the pressing member to prevent it from sliding on the fixing plate. In the implementation where the medium plate is a foamed board, the recess may be formed by extruding the fixing plate. The extruded foamed board has greater strength, which can prevent the foamed board in contact with the pressing member from deforming.

[0017] In some embodiments that may include the above-described examples, a connector is provided on the conductive component, and the connector is connected to the fixing plate. The conductive component and the connector can fix the fixing plate to the reflector, thereby achieving a fixed connection between the antenna support and the reflector. With this configuration, the conductive component can couple signals to the feed line, and at the same time, it can also fix the antenna support, simplifying the antenna structure.

[0018] In some embodiments that may include the above-described examples, the connector includes a fixing post, which is disposed at the end of the conductive component facing the fixing plate. The fixing plate has a fixing hole, and the fixing post passes through the fixing hole. The fixing plate and the reflector are fixed together by the cooperation between the fixing post and the fixing hole, resulting in a reliable connection and a simple structure.

[0019] In some embodiments that may include the above-described examples, the fixing post is provided with a fixing external thread, and the connector also includes a fixing nut. The fixing nut is located on the side of the fixing plate away from the reflector, and the fixing nut engages with the fixing external thread. With this configuration, the fixing plate can be disassembled and installed from the reflector simply by installing and removing the fixing nut, thus facilitating the disassembly and installation of the antenna bracket.

[0020] In some embodiments that may include the above-described examples, the side of the fixing plate facing away from the reflector is provided with solder for welding to the fixing post. Connecting the fixing post and the fixing plate by welding can improve the connection strength between the fixing post and the fixing plate, and also facilitates the assembly of the fixing post and the fixing plate.

[0021] In some embodiments that may include the above-described examples, the conductive component has a first threaded hole at the end facing the fixed plate, and the fixed post has a first external thread that engages with the first threaded hole. A cap is provided at the end of the fixed post facing away from the reflector, and the cap abuts against the side of the fixed plate facing away from the reflector. For example, the cap can be an integral part of the fixed post for ease of manufacturing. Furthermore, the installation and removal of the fixed post and the conductive component can be achieved by twisting the cap, facilitating the installation and removal of the antenna bracket.

[0022] In some embodiments that may include the above-described examples, the connector further includes a clamping block disposed within a fixing hole. The clamping block has a clamping groove on its outer wall, and a fixing plate at the edge of the fixing hole clamps within the clamping groove. The clamping block has a second threaded hole, and the fixing post has a second external thread that engages with the second threaded hole. With this configuration, installation and disassembly of the clamping block and the fixing post can be achieved by twisting the clamping block, thereby facilitating the installation and disassembly of the antenna bracket.

[0023] In some embodiments that may include the above-described examples, the connector further includes a card that connects to the fixing plate. The card has a locking hole, and a locking block is provided on the inner wall of the locking hole. The fixing post passes through the locking hole, and the locking block abuts against the fixing post, preventing the fixing post from moving within the locking hole. With this configuration, fixing the fixing plate and the reflector can be achieved simply by inserting the fixing post through the locking hole, resulting in a simple structure and convenient installation.

[0024] In some embodiments that may include the above-described examples, the connector includes an expansion joint disposed on a conductive component. A fixing hole is provided on the fixing plate, and the expansion joint is disposed within the fixing hole. After expansion, the expansion joint connects to the fixing plate. This configuration allows the expansion joint to be expanded using an expansion tool after being installed in the fixing hole, thus facilitating its connection to the fixing plate and simplifying the fixing of the fixing plate.

[0025] In some embodiments that may include the above-described embodiments, the expansion joint may include a first fixed arm and a second fixed arm spaced apart. One end of each of the first and second fixed arms is connected to a conductive element, and the other end of each of the first and second fixed arms is provided with a limiting block. After the expansion joint is installed in the fixing hole, the expansion joint is placed between the first and second fixed arms. The expansion joint tooling causes the first and second fixed arms to undergo plastic deformation and move away from each other. At this time, the first and second fixed arms can be interference-fitted with the fixing hole, and the limiting block abuts against the surface of the fixing plate away from the reflector to fix the fixing plate.

[0026] In some embodiments that may include the above-described examples, the feed element includes a conductive post connected to the reflector. The conductive post is coupled to the feed line and is used to receive radio frequency signals. This configuration allows for the fixing of the mounting plate and the reflector via the conductive post, while also enabling signal coupling to the feed line, thus simplifying the antenna structure.

[0027] In some embodiments that may include the above examples, the conductive post and the antenna support are integrated into a single structure to reduce the fabrication difficulty of the antenna structure. It is understood that the conductive post may include a portion of the dielectric substrate and a conductive sidewall located on the outer side of the dielectric substrate. One end of the conductive sidewall is connected to the feed line, and the other end is used to receive radio frequency signals. Of course, in other implementations, the conductive post can also be connected to the mounting plate by means of adhesive bonding, bolting, snap-fitting, etc.

[0028] In the implementation of the dielectric plate including the foamed plate, the conductive post can be formed by extruding the dielectric plate. The extruded dielectric plate has greater strength, which can improve the connection force between the fixed plate and the reflector.

[0029] In the implementation of the feed component including connectors, a recessed portion can be provided on the fixing plate, and the connector can be connected to the recessed portion. Part of the connector can be located within the recessed portion to facilitate the miniaturization of the antenna structure. In the implementation where the dielectric substrate is a foamed board, the recessed portion can be formed by extruding the fixing plate. The extruded foamed board has greater strength, which can prevent the foamed board in contact with the connector from deforming.

[0030] In some embodiments that may include the above-described embodiments, the antenna structure further includes an auxiliary support and a second radiator. The auxiliary support is disposed on the side of the antenna support opposite to the reflector, and the second radiator is disposed on the auxiliary support. The first radiator is used to couple signals to the second radiator. With this configuration, the first radiator can simultaneously transmit signals outward and couple signals to the second radiator, enabling the second radiator to transmit signals outward, thereby improving the gain of the antenna structure and enhancing its communication performance.

[0031] For example, the auxiliary support is plate-shaped and arranged parallel to the reflector, with a gap between it and the antenna support; the second radiator includes a conductive sheet and is attached to the auxiliary support. This arrangement results in a smaller thickness and mass of the second radiator, thus reducing the overall mass of the antenna structure.

[0032] In some embodiments that may include the above-described embodiments, the feed line includes a first line and a second line spaced apart, and the feed element includes a first feed element and a second feed element spaced apart on the reflector. The first feed element is coupled to the first line, and the second feed element is coupled to the second line. The first feed element is used to receive a first signal, causing the first radiator to generate a first polarization signal, and the second feed element is used to receive a second signal, causing the first radiator to generate a second polarization signal. This configuration allows the first and second polarization signals to have different polarization directions, enabling the antenna structure to transmit and receive signals with different polarization directions, thus improving the versatility of the antenna structure.

[0033] In some embodiments that may include the above-described embodiments, a limiting rib is provided between the antenna support and the reflector. This configuration limits the distance between the antenna support and the reflector, i.e., limits the distance between the first radiator and the reflector, improving the positional accuracy between the antenna support and the reflector, thus ensuring that the signal reflected by the reflector can be received by the first radiator.

[0034] In some implementations, the limiting rib can be made of insulating materials such as plastic or rubber, in which case the limiting rib can cover the feed lines on the antenna support. In other implementations, the limiting rib can be made of conductive materials such as copper, aluminum, or iron. In this case, the limiting rib needs to avoid the feed lines on the antenna support to prevent interference with the feed lines.

[0035] In the implementation of a power supply line including a first line and a second line, and a power supply component including a first power supply component and a second power supply component, a limiting rib made of conductive material can be set between the first power supply component and the second power supply component. The limiting rib can achieve isolation between the first power supply component and the second power supply component to prevent the signals in the first power supply component and the second power supply component from interfering with each other.

[0036] Secondly, embodiments of this application also provide a communication base station, including: a radio frequency device and an antenna structure as described above, wherein the radio frequency device is coupled to a feeding device. The communication base station provided in this application includes the antenna structure of any of the above embodiments, and therefore can achieve the same technical effects and solve the same technical problems, which will not be elaborated further here.

[0037] Thirdly, embodiments of this application also provide an active antenna unit, including: a radio frequency device and the antenna structure described above, wherein the radio frequency device is integrated into the antenna structure. The active antenna unit provided in this application includes the antenna structure of any of the above embodiments, and therefore can achieve the same technical effects and solve the same technical problems, which will not be elaborated further here.

Detailed Implementation

[0067] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0068] This application provides a communication base station that enables communication with electronic devices such as mobile phones. For example, the communication base station can receive wireless signals from electronic devices and transmit wireless signals to them. Referring to Figure 1, the communication base station may include an antenna structure 10 and a radio frequency (RF) device. The antenna structure 10 is used to receive and transmit wireless signals, and the RF device is coupled to the antenna structure 10, enabling the RF device to transmit RF signals to and receive signals from the antenna structure 10. The RF device may include filters, amplifiers, etc., and can transmit RF signals to and process signals from the antenna structure 10. For example, the RF device may include a Remote Radio Unit (RRU), which can transmit and receive RF signals.

[0069] It is understood that the coupling in the embodiments of this application can be understood as direct coupling and / or indirect coupling. Direct coupling can also be called "electrical connection", which can be understood as the physical contact and electrical conduction of components; it can also be understood as the form of connection between different components in the circuit structure through physical lines such as copper foil of printed circuit board (PCB) or wires that can transmit electrical signals; "indirect coupling" can be understood as two conductors conducting electricity in a way that is airtight or non-contact.

[0070] In some embodiments, the communication base station further includes a mounting frame 20 and a pole 201. The pole 201 can be erected on the ground or on a building (such as a rooftop, wall, etc.). The pole 201 serves as a base, the mounting frame 20 is connected to the pole 201, and the antenna structure 10 is connected to the mounting frame 20 to fix the antenna structure 10.

[0071] For example, the mounting bracket 20 includes a frame 204, a first clamp 202, and a second clamp 203. The first clamp 202 and the second clamp 203 are detachably connected to the mounting rod 201. The first clamp 202 is connected to one end of the frame 204, the other end of the frame 204 is connected to the top of the antenna structure 10, and the second clamp 203 is connected to the bottom of the antenna structure 10. By rotating the first clamp 202 and the second clamp 203 relative to the centerline of the mounting rod 201, the coverage area of ​​the antenna structure 10 can be adjusted.

[0072] In some implementations, the frame 204 may include a first rod and a second rod. One end of the first rod is hinged to a first clamp 202, and the other end of the first rod is hinged to one end of the second rod. The other end of the second rod is hinged to the antenna structure 10. A limiting structure is also provided between the first rod and the second rod to limit the included angle between the first rod and the second rod, thereby adjusting the elevation angle of the antenna structure 10. For example, the limiting structure may include a first limiting plate, a second limiting plate, and a limiting pin. The first limiting plate is connected to the first rod, and the second limiting plate is connected to the second rod. The rotation axes of the first and second limiting plates coincide with the hinge axis between the first and second rods. The first limiting plate has multiple first limiting holes arranged at equal central angles around the rotation axis of the first limiting plate. The second limiting plate has a second limiting hole, and the limiting pin passes through the second limiting hole and one of the first limiting holes to prevent the first rod and the second rod from rotating relative to each other. By inserting the limiting pin into the second limiting hole and different first limiting holes, the angle between the first rod and the second rod can be adjusted, thereby adjusting the elevation angle of the antenna structure 10.

[0073] Referring to Figure 2, in this embodiment, the antenna structure 10 includes a first radiator 120, which includes a conductive sheet. It is understood that the conductive sheet may include a metal sheet, graphite sheet, etc., and this embodiment does not limit the material of the conductive sheet. A radiator is a device for receiving and transmitting electromagnetic wave radiation. It converts guided wave energy from a radio frequency device into radio waves, or converts radio waves into guided wave energy, for transmitting and receiving wireless signals. The conductive sheet may have a specific shape and size, such as a wire. In one embodiment, a groove or slot is formed on the conductive sheet, and wireless signals are transmitted and received through the slot and the conductive sheet surrounding the slot.

[0074] Referring again to Figure 2, in some embodiments, there may be multiple first radiators 120, which can be arranged in an array. Multiple first radiators 120 can simultaneously receive and transmit wireless signals to improve signal reception and transmission power. Exemplarily, the antenna structure 10 may also include a phase shifter. The first radiators 120 are coupled to the radio frequency device via the phase shifter, which can adjust the phase of the radio frequency signal. In some implementations, the antenna structure 10 further includes an adjustment device connected to the phase shifter, which can adjust the phase shift amount of the phase shifter. The phase shifter may include a capacitive phase shifter, comprising a first conductive plate and a second conductive plate arranged parallel and spaced apart. The adjustment device may include a driving mechanism connected to the first conductive plate, which can drive the first conductive plate to rotate or move, thereby changing the overlapping area of ​​the first and second conductive plates, and thus adjusting the impedance of the phase shifter to achieve phase shift adjustment. The driving mechanism may include a driving rod or a driving handle, etc. The overlapping area of ​​the first conductive plate and the second conductive plate can be adjusted by twisting or moving the driving mechanism; of course, the driving mechanism may also include a motor, the main shaft of which is connected to the first conductive plate, and the first conductive plate can also be driven to rotate or move by the motor.

[0075] The antenna structure 10 may also include a combiner or a filter. The phase shifter is coupled to the radio frequency device through the combiner or filter. The filter can filter out noise in the radio frequency signal to improve the communication effect. The combiner enables the first radiator 120 to transmit and receive wireless signals in multiple frequency bands, thereby improving the operating bandwidth of the antenna assembly.

[0076] Figure 3 is a cross-sectional view of the antenna structure provided in this application embodiment along a direction approximately perpendicular to the center line of the antenna support 110. Figure 4 is a perspective view of the antenna support 110 in the antenna structure shown in Figure 3. Referring to Figures 3 and 4, the antenna structure 10 also includes the antenna support 110. The antenna support 110 is formed by folding the dielectric substrate 111 around a preset center line. That is, the antenna support 110 can be approximately columnar, and the center line of the antenna support 110 can be set parallel to the preset center line.

[0077] The cross section of the antenna support 110 perpendicular to the preset center line can be in a trapezoidal, rectangular, triangular or other regular shape to reduce the difficulty of bending the dielectric substrate 111 and reduce the difficulty of manufacturing and installing the antenna structure 10; of course, the cross section of the antenna branch perpendicular to the preset center line can also be in other irregular shapes, and this application embodiment does not limit this.

[0078] Referring again to Figure 4, in this embodiment, the first radiator 120 includes a conductive sheet with a relatively small thickness (less than the thickness of the dielectric substrate 111). The first radiator 120 is attached to the antenna support 110, that is, the first radiator 120 is attached to the dielectric substrate 111 to fix the first radiator 120 to the antenna support 110, thereby achieving fixation of the first radiator 120. For example, the first radiator 120 can be connected to the surface of the antenna support 110 by adhesive, or the first radiator 120 can be connected to the surface of the antenna support 110 by pressing. This embodiment does not limit this.

[0079] For example, the first radiator 120 can be attached to the outer surface of the antenna bracket 110 so that the first radiator 120 can receive and transmit wireless signals; of course, the first radiator 120 can also be attached to the inner surface of the antenna bracket 110 so as to prevent external objects from contacting the first radiator 120 and scratching it.

[0080] As shown in Figures 3 and 4, in the implementation where the cross-section of the antenna support 110 perpendicular to the preset center line is trapezoidal, the portion of the dielectric substrate 111 corresponding to the upper base (the shorter base) of the trapezoid can be positioned approximately facing the coverage area, and correspondingly, the first radiator 120 can be attached to the portion of the dielectric substrate 111 corresponding to the upper base. Alternatively, as shown in Figures 5 and 6, the portion of the dielectric substrate 111 corresponding to the lower base (the longer base) of the trapezoid can be positioned facing the coverage area, and correspondingly, the first radiator can be attached to the portion of the dielectric substrate 111 corresponding to the lower base.

[0081] As shown in Figure 7, in the implementation of the antenna support 110 having a rectangular cross-section perpendicular to the preset center line, the portion of the dielectric substrate 111 corresponding to one side of the rectangle is generally set facing the coverage area, and the first radiator can be attached to the portion of the dielectric substrate 111 corresponding to that side.

[0082] As shown in Figure 8, in the implementation of the antenna support 110 having a triangular cross section perpendicular to the preset center line, the portion of the dielectric plate 111 corresponding to the two sides of one vertex of the triangle can be set to face the coverage area. Correspondingly, the first radiator 120 can be attached to the portion of the dielectric plate 111 corresponding to these two sides.

[0083] In the above embodiments, the antenna support 110 formed by folding the dielectric substrate 111 can be a closed support, that is, the dielectric substrate 111 is folded around a preset center line. Alternatively, as shown in FIG3, the antenna support 110 is a support with an opening 115, that is, the dielectric substrate 111 is folded less than one revolution around the preset center line to form an opening 115. For example, in the implementation where the cross-section of the antenna support 110 is trapezoidal, when the first radiator 120 is placed on the dielectric substrate 111 corresponding to the upper base of the trapezoid, the portion of the dielectric substrate 111 corresponding to the lower base of the trapezoid can form an opening 115; or, as shown in FIG5, when the first radiator 120 is placed on the dielectric substrate 111 corresponding to the lower base of the trapezoid, the portion of the dielectric substrate 111 corresponding to the upper base of the trapezoid can form an opening 115. As shown in FIG8, in the implementation where the cross-section of the antenna support 110 is triangular, an opening 115 can be formed near the edge corresponding to the vertex facing the coverage area. As shown in Figure 7, in the implementation where the cross-section of the antenna support 110 is rectangular, an opening 115 can be provided on the portion of the dielectric substrate 111 opposite to where the first radiator 120 is located. By providing the opening 115, the mass of the antenna support 110 can be reduced while ensuring that the antenna support 110 has sufficient strength.

[0084] In this embodiment, the dielectric board 111 may include at least one of a foamed board, a resin board, and a rubber board. This embodiment does not limit the material of the dielectric board 111. The foamed board can be a sheet made of a foamed material, which can be a substrate with a bubble structure. This bubble structure can be formed inside the substrate by physical or chemical means. Because the foamed board has a bubble structure, its dielectric constant is closer to that of air, which can reduce dielectric loss.

[0085] Referring again to Figure 3, the antenna structure 10 in this embodiment further includes a reflector 130. The reflector 130 is disposed on one side of the antenna support 110. The reflector 130 is used to reflect signals to the first radiator 120. That is, the reflector 130 is disposed on the side of the first radiator 120 away from the coverage area. The reflector 130 can reflect external wireless signals to the first radiator 120 to improve the received signal strength. At the same time, the reflector 130 can also reflect signals emitted by the first radiator 120 in the direction away from the coverage area back to the coverage area to improve the signal transmission power of the antenna structure 10.

[0086] For example, the material of reflector 130 may include a metal plate such as copper or aluminum; of course, the material of reflector 130 may also include a non-metallic conductive plate such as graphite. In some examples, reflector 130 may be configured to be grounded or have a certain potential.

[0087] Referring again to Figures 3 and 4, the antenna structure 10 further includes a feed element 140, which is disposed on the reflector 130. A feed line 121 is disposed on the antenna support 110. One end of the feed line 121 is coupled to the first radiator 120, and the other end is coupled to the feed element 140. The feed element 140 receives radio frequency signals from the radio frequency device and transmits these signals to the first radiator 120 via the feed line 121. For example, the feed line 121 may include metal lines attached to the surface of the dielectric substrate 111 to facilitate signal transmission to the first radiator 120 and simplify the wiring of the antenna structure 10.

[0088] The antenna structure 10 provided in this embodiment includes an antenna support 110 formed by folding a dielectric substrate 111 around a predetermined centerline. A first radiator 120 includes a conductive sheet attached to the antenna support 110. A feed line 121 coupled to the first radiator 120 is provided on the antenna support 110. A reflector 130 is disposed on one side of the antenna support 110 and is used to reflect signals to the first radiator 120. A feed element 140 is disposed on the reflector 130 and coupled to the feed line 121 to transmit signals to the first radiator 120. The first radiator 120, including the conductive sheet, is attached to the antenna support 110. The thickness of the first radiator 120 can be set to be relatively small, thereby reducing the mass of the first radiator 120 and the antenna structure 10.

[0089] On the other hand, the antenna support 110 is formed by folding the dielectric substrate 111 around a preset center, that is, the antenna support 110 is a hollow support, which can further reduce the mass of the antenna structure 10; and the folded antenna support 110 is easier to manufacture and assemble.

[0090] In this embodiment, the antenna structure 10 may further include a housing, with the antenna support 110 and the reflector 130 both disposed within the housing, so as to protect the antenna support 110 and the reflector 130 through the housing.

[0091] In some examples, the antenna structure 10 includes multiple antenna supports 110, with the multiple antennas 110 spaced apart. Each antenna support 110 is provided with at least one first radiator 120. The first radiators 120 on each antenna support 110 can simultaneously transmit and receive signals in the same frequency band to improve the transmission and reception power of the signals. Of course, among the multiple antenna supports 110, the frequency bands of the signals transmitted and received by the first radiators 120 on several antenna supports 110 can also be different from those of the signals transmitted and received by the first radiators 120 on other antenna supports 110, so that the antenna structure 10 can cover different communication frequency bands, thereby increasing the bandwidth of the antenna structure 10.

[0092] Figure 9 is a bottom view of the antenna structure shown in Figure 3. Referring to Figures 3, 4, and 9, in this embodiment, the feed line 121 includes a first line 122 and a second line 123 spaced apart. The feed element 140 includes a first feed element 168 and a second feed element 169 spaced apart on the reflector 130. The first feed element 168 is coupled to the first line 122, and the second feed element 169 is coupled to the second line 123. The first feed element 168 is used to receive a first signal, causing the first radiator 120 to generate a first polarization signal. The second feed element 169 is used to receive a second signal, causing the first radiator 120 to generate a second polarization signal. With this configuration, the first polarization signal and the second polarization signal have different polarization directions, allowing the antenna structure 10 to transmit and receive signals with different polarization directions, thus improving the versatility of the antenna structure 10.

[0093] In some implementations, the first radiator 120 includes a first sub-radiator and a second sub-radiator, a first line 122 is coupled to the first sub-radiator, and a second line 123 is coupled to the second sub-radiator. The first sub-radiator is used to transmit and receive a first polarization signal, and the second sub-radiator is used to transmit and receive a second polarization signal.

[0094] Referring to Figures 3 and 5, in the implementation where the antenna support 110 has an opening 115, the first sub-radiator can be located on the dielectric substrate 111 on one side of the opening 115, and the second sub-radiator can be located on the dielectric substrate 111 on the other side of the opening 115. In other implementations, as shown in Figure 8, the dielectric substrate 111 can have a slot 116, with the first sub-radiator disposed on the dielectric substrate 111 on one side of the slot 116, and the second sub-radiator disposed on the dielectric substrate 111 on the other side of the slot 116. By providing the opening 115 and the slot 116, isolation between the first and second sub-radiators can be achieved.

[0095] Referring again to Figure 3, in this embodiment, a limiting rib 133 is provided between the antenna support 110 and the reflector 130. Exemplarily, the limiting rib 133 can be disposed on either the antenna support 110 or the reflector 130; this embodiment does not impose any limitations on this. This arrangement limits the distance between the antenna support 110 and the reflector 130, i.e., limits the distance between the first radiator 120 and the reflector 130, thereby improving the positional accuracy between the antenna support 110 and the reflector 130 and ensuring that the signal reflected by the reflector 130 can be received by the first radiator 120.

[0096] In some implementations, the limiting rib 133 may be made of insulating materials such as plastic or rubber, in which case the limiting rib 133 can cover the feed line 121 on the antenna bracket 110. In other implementations, the limiting rib 133 may be made of conductive materials such as copper, aluminum, or iron, in which case the limiting rib 133 needs to avoid the feed line 121 on the antenna bracket 110 to prevent interference with the feed line 121.

[0097] Additionally, as shown in Figures 3 and 9, in the implementation where the power supply line 121 includes a first line 122 and a second line 123, and the power supply component 140 includes a first power supply component 168 and a second power supply component 169, a limiting rib 133 made of conductive material can be disposed between the first power supply component 168 and the second power supply component 169. The limiting rib 133 can achieve isolation between the first power supply component 168 and the second power supply component 169 to prevent the signals in the first power supply component 168 and the second power supply component 169 from interfering with each other.

[0098] Referring to Figures 10 and 11, in this embodiment, the antenna structure 10 further includes an auxiliary support 150 and a second radiator 151. The auxiliary support 150 is disposed on the side of the antenna support 110 opposite to the reflector 130, and the second radiator 151 is disposed on the auxiliary support 150. The first radiator 120 (as shown in Figure 4) is used to couple signals to the second radiator 151. With this configuration, the first radiator 120 can simultaneously transmit signals and couple signals to the second radiator 151, enabling the second radiator 151 to transmit signals, thereby increasing the gain of the antenna structure 10 and improving its communication performance.

[0099] For example, the auxiliary support 150 is plate-shaped, and is arranged parallel to the reflector 130 and spaced apart from the antenna support 110; the second radiator 151 includes a conductive sheet and is attached to the auxiliary support 150. This arrangement results in a smaller thickness and mass of the second radiator 151, thus reducing the mass of the antenna structure 10.

[0100] For example, the auxiliary support 150 and the dielectric substrate 111 may be made of the same or different materials, and this embodiment of the application does not limit this. The auxiliary support 150 may be connected to the reflector 130 to fix the auxiliary support 150 on the side of the antenna support 110 away from the reflector 130; for example, the antenna structure 10 may include a support frame, one end of which is connected to the reflector 130, and the other end of which is connected to the auxiliary support 150 to fix the auxiliary support 150.

[0101] Referring to Figures 10 and 12, in some implementations, the antenna support 110 has an opening 115 that can face the auxiliary support 150. Referring to Figure 13, in other implementations, the antenna support 110 has a slit 116 that can face the auxiliary support 150.

[0102] Referring to Figure 14, in some embodiments, the medium plate 111 can be a flat plate, that is, the surface of the medium plate 111 is flat before folding. When folding, specific tooling is needed to limit the crease position to ensure accurate folding position.

[0103] Referring to Figure 15, in other embodiments, the dielectric substrate 111 is folded along multiple creases to form the antenna support 110. A groove 117 may be provided at the crease of the dielectric substrate 111, with the length direction of the groove 117 parallel to the crease; that is, the dielectric substrate 111 bends at the groove 117. This arrangement allows the groove 117 to facilitate the bending of the dielectric substrate 111 and also controls the folding position, thereby improving the shape and dimensional accuracy of the antenna support 110.

[0104] It is understood that the groove 117 can be formed by cutting, extrusion, or other methods to facilitate the formation of the groove 117 on the dielectric plate 111. The cross-section of the groove 117 can be a regular shape such as rectangular (as shown in Figure 15), triangular (as shown in Figure 16), approximately semi-circular (as shown in Figure 17), or approximately elliptical. Of course, the cross-section of the groove 117 can also be other irregular shapes (as shown in Figure 18), and this embodiment does not limit this.

[0105] The manufacturing process of the antenna support 110 in this embodiment can be as follows: the first radiator 120 is installed on the dielectric substrate 111, then a groove 117 is formed on the dielectric substrate 111, then the cut-off plate is folded along the groove 117, then the dielectric substrate 111 is placed in a shaping mold, the shaping mold can keep the dielectric substrate 111 in its folded shape, and then the dielectric substrate 111 is taken out from the shaping mold to form an antenna support 110 with a certain shape.

[0106] Referring again to Figure 3, in this embodiment, the antenna support 110 further includes a fixing plate 112, which is attached to the reflector 130 and connected to the reflector 130. This arrangement allows for the fixing of the antenna support 110 and the reflector 130 via the fixing plate 112, improving the structural compactness of the antenna structure 10.

[0107] For example, the fixing plate 112 can be formed by folding a portion of the dielectric plate 111, which can simplify the structure of the antenna bracket 110 and reduce the manufacturing difficulty of the antenna bracket 110.

[0108] In some embodiments, the fixing plate 112 may be located inside the space enclosed by the antenna support 110 to avoid the fixing plate 112 occupying the space outside the antenna support 110, thus facilitating the miniaturization of the antenna structure 10. Of course, the fixing plate 112 may also be located outside the space enclosed by the antenna support 110 to facilitate the connection between the fixing plate 112 and the reflector 130.

[0109] In the above implementation, the feed line 121 extends to the fixing plate 112, and a portion of the feed line 121 on the fixing plate 112 is coupled to the feed element 140. Since the feed element 140 is located on the reflector 130, and the fixing plate 112 is in contact with the reflector 130, the connection between the feed line 121 and the feed element 140 is facilitated by the coupling of a portion of the feed line 121 on the fixing plate 112 to the feed element 140.

[0110] In some examples, the feed line 121 may extend to the surface of the fixing plate 112 facing the reflector 130 to reduce the distance between the feed line 121 on the fixing plate 112 and the feed element 140. In other examples, the feed line 121 on the fixing plate 112 may be located on the surface of the fixing plate 112 away from the reflector 130; or the feed line 121 may be provided on both surfaces of the fixing plate 112. This application embodiment does not limit this.

[0111] For example, in an implementation where the power supply component 140 includes a first power supply component 168 and a second power supply component 169, the fixing plate 112 may include a first fixing plate 113 and a second fixing plate 114 spaced apart. The first line 122 may extend to the first fixing plate 113 and is coupled to the first power supply component 168. The second line 123 may extend to the second fixing plate 114 and is coupled to the second power supply component 169.

[0112] Figure 19 is a schematic diagram of the connection between the antenna support and the reflector in the antenna structure provided in this embodiment. Referring to Figure 19, in this embodiment, the reflector 130 is provided with a first through hole 131. The feed component 140 includes a conductive component 142, which is disposed in the first through hole 131. One end of the conductive component 142 is in contact with the feed line 121, and the other end of the conductive component 142 is used to receive radio frequency signals. With this configuration, the coupling between the feed component 140 and the feed line 121 is achieved through the contact between the conductive component 142 and the feed line 121. The structure is simple, the connection is reliable, and it is easy to install and disassemble.

[0113] Referring again to Figure 3, in some implementations, the power supply component 140 further includes an insulating block 141. The insulating block 141 is disposed in the first through hole 131, and the conductive component 142 passes through the insulating block 141. The insulating block 141 can achieve insulation between the conductive component 142 and the reflector 130.

[0114] It is understood that the material of the insulating block 141 may include insulating materials such as plastic and rubber to achieve insulation between the conductive element 142 and the reflector 130. The conductive element 142 may be columnar or other irregular shapes. The end of the conductive element 142 facing the fixing plate 112 may be exposed or protrude from the insulating block 141 to facilitate contact between the conductive element 142 and the feed line 121. A connector may be provided at the end of the conductive element 142 away from the fixing plate 112. The antenna structure 10 may also include a cable, which may include a coaxial cable. The inner conductor at one end of the coaxial cable may be connected to the connector, and the other end of the coaxial cable may be connected to the radio frequency device so that the radio frequency device can transmit signals to or receive signals from the antenna structure 10 through the coaxial cable.

[0115] In some embodiments, the antenna structure 10 further includes a crimping member 132, which is connected to the reflector 130, and a fixing plate 112 is sandwiched between the crimping member 132 and the reflector 130. This configuration allows the fixing plate 112 to be fixed to the reflector 130 via the crimping member 132, resulting in a reliable connection and a simple structure. It is understood that while the crimping member 132 presses the fixing plate 112 onto the reflector 130, it also ensures good contact between the conductive element 142 and the feed line 121.

[0116] For example, the crimping member 132 may include a crimping rod disposed on the side of the fixing plate 112 opposite to the reflector 130. The crimping rod is connected to the reflector 130 by bolts to ensure that the crimping rod presses the fixing plate 112 against the reflector 130, thereby fixing the fixing plate 112 onto the reflector 130. Alternatively, the crimping rod may be connected to the reflector 130 by a spring, so that the crimping rod presses the fixing plate 112 against the reflector 130 under the elastic force of the spring.

[0117] In the above implementation, a recess 119 can be provided on the fixing plate 112, and a pressing member 132 can be provided at the recess 119. The recess 119 can restrict the position of the pressing member 132 to prevent the pressing member 132 from sliding on the fixing plate 112. In the implementation where the medium plate 111 is a foamed board, the recess 119 can be formed by extruding the fixing plate 112. The extruded foamed board has greater strength and can prevent the foamed board in contact with the pressing member 132 from deforming.

[0118] Figure 20 is a schematic diagram of the connection between the antenna support and the reflector in the antenna structure provided in this application embodiment. Referring to Figure 20, in some embodiments, a connector 143 is provided on the conductive member 142, and the connector 143 is connected to the fixing plate 112. The fixing plate 112 can be fixed on the reflector 130 through the conductive member 142 and the connector 143, thereby realizing the fixed connection between the antenna support 110 and the reflector 130. With this configuration, the conductive member 142 can couple signals to the feed line 121, and at the same time, the conductive member 142 can also fix the antenna support 110, simplifying the structure of the antenna structure 10. It is understood that the structure of the connector 143 is not limited in this application embodiment, as long as it can fix the fixing plate 112 on the reflector 130.

[0119] In some implementations, the connector 143 includes a fixing post 144, which is disposed at the end of the conductive member 142 facing the fixing plate 112. Correspondingly, the fixing plate 112 is provided with a fixing hole 118, and the fixing post 144 passes through the fixing hole 118. The fixing plate 112 and the reflector 130 are fixed by the cooperation between the fixing post 144 and the fixing hole 118, which is reliable and simple in structure.

[0120] In some examples, the connector 143 also includes a fixing nut 145, which is located on the side of the fixing plate 112 facing away from the reflector 130. The fixing post 144 has a fixing external thread on its sidewall, which engages with the fixing nut 145 to press the fixing plate 112 onto the reflector 130, thus securing the fixing plate 112. This configuration allows for easy installation and removal of the fixing nut 145, facilitating the disassembly and installation of the antenna bracket 110.

[0121] In some implementations, the power supply line 121 is also disposed on the surface of the fixing plate away from the reflector plate 130. In this case, the power supply line 121 can be electrically connected to the conductive element 142 through the fixing nut 145 and the fixing post 144.

[0122] Figure 21 is a schematic diagram of the connection between the antenna support and the reflector in the antenna structure provided in this application embodiment. Referring to Figure 21, in some examples, the fixing post 144 passes through the fixing hole 118, and the fixing plate 112 is provided with solder 146 for welding to the fixing post 144 on the side opposite to the reflector 130. Connecting the fixing post 144 and the fixing plate 112 by welding can improve the connection strength between the fixing post 144 and the fixing plate 112, and also facilitate the assembly between the fixing post 144 and the fixing plate 112.

[0123] In some implementations, the power supply line 121 is also disposed on the surface of the fixing plate away from the reflector plate 130. In this case, the power supply line 121 can be electrically connected to the conductive element 142 through solder 146 and fixing post 144.

[0124] Figure 22 is a schematic diagram of the connection between the antenna support and the reflector in the antenna structure provided in this application embodiment. Referring to Figure 22, in some examples, the conductive element 142 has a first threaded hole 148 at the end facing the fixed plate 112, and the fixed post 144 has a first external thread that engages with the first threaded hole 148. The fixed post 144 has a cap 147 at the end facing away from the reflector 130, and the cap 147 abuts against the side of the fixed plate 112 facing away from the reflector 130. For example, the cap 147 can be an integral structure with the fixed post 144 for ease of manufacturing. In addition, the installation and disassembly of the fixed post 144 and the conductive element 142 can be achieved by twisting the cap 147, which facilitates the installation and disassembly of the antenna support 110.

[0125] In some implementations, the power supply line 121 is also disposed on the surface of the fixing plate away from the reflector plate 130. In this case, the power supply line 121 can be electrically connected to the conductive element 142 through the top cap 147 and the fixing post 144.

[0126] Figure 23 is a schematic diagram of the connection between the antenna support and the reflector in the antenna structure provided in this application embodiment. Referring to Figure 23, in some examples, the connector 143 further includes a clamping block 161. The clamping block 161 is disposed in the fixing hole 118, and a clamping groove is provided on the outer wall of the clamping block 161. The fixing plate 112 at the edge of the fixing hole 118 is clamped in the clamping groove. The clamping block 161 and the fixing plate 112 can be interference-fitted to achieve fixation between the clamping block 161 and the fixing plate 112. A second threaded hole is provided on the clamping block 161, and a second external thread is provided on the fixing post 144. The second external thread engages with the second threaded hole, and the second clamping block 161 can press the fixing plate 112 against the reflector 130 to achieve fixation between the fixing plate 112 and the reflector 130. With the above configuration, the installation and disassembly of the clamping block 161 and the fixing post 144 can be achieved by twisting the clamping block 161, thereby facilitating the installation and disassembly of the antenna support 110.

[0127] It is understood that the power supply line 121 on the fixed plate 112 is in contact with the clamping block 161, and the conductive element 142 is electrically connected to the power supply line 121 through the fixed post 144 and the clamping block 161 to couple signals to the power supply line 121.

[0128] Figure 24 is a schematic diagram of the connection between the antenna support and the reflector in the antenna structure provided in this application embodiment. Figure 25 is a schematic diagram of the card structure in Figure 24. Please refer to Figures 24 and 25. In some examples, the connector 143 also includes a card 163. The card 163 is connected to the fixing plate 112. The card 163 is provided with a card hole 164. A card block 165 is provided on the inner wall of the card hole 164. The fixing post 144 passes through the card hole 164. The card block 165 abuts against the fixing post 144. The card block 165 is used to prevent the fixing post 144 from moving within the card hole 164. During installation, when the fixing post 144 is passed through the card hole 164, the fixing post 144 abuts against the card block 165, causing the card block 165 to undergo elastic deformation. The card block 165 and the fixing post 144 are interference-fitted to prevent the fixing post 144 from moving within the card hole 164, thereby fixing the fixing plate 112. With this setup, the fixing plate 112 and the reflector 130 can be fixed simply by inserting the fixing post 144 through the clip hole 164. The structure is simple and easy to install.

[0129] In the above implementation, the card 163 can be disposed on the surface of the fixing plate 112 facing the reflector 130. In this case, the card 163 can be soldered to the feed line 121 on the surface of the fixing plate 112 facing the reflector 130 to fix the card 163 to the fixing plate 112. At the same time, the electrical connection between the conductive element 142 and the feed line 121 can be realized through the card 163 and the fixing post 144. In other implementations, the card 163 can also be disposed on the surface of the fixing plate 112 away from the reflector 130. In this case, the card 163 can press the fixing plate 112 against the reflector 130 to fix the fixing plate 112.

[0130] Figure 26 is a schematic diagram of the connection between the antenna support and the reflector in the antenna structure provided in this application embodiment. Referring to Figure 26, in some examples, the connector 143 includes an expansion joint 166 disposed on the conductive member 142. The fixing plate 112 is provided with a fixing hole 118, and the expansion joint 166 is disposed in the fixing hole 118. After the expansion joint 166 is expanded, it connects with the fixing plate 112. With this configuration, after the expansion joint 166 is installed in the fixing hole 118, the expansion joint 166 is expanded by the expansion tool to connect the expansion joint 166 with the fixing plate 112, which facilitates the fixing of the fixing plate 112.

[0131] In the above implementation, the expansion joint 166 may include a first fixed arm and a second fixed arm spaced apart. One end of each of the first and second fixed arms is connected to the conductive element 142, and the other end of each of the first and second fixed arms is provided with a limiting block. After the expansion joint 166 is installed in the fixing hole 118, the expansion joint is placed between the first and second fixed arms. The expansion joint tooling causes the first and second fixed arms to undergo plastic deformation and move away from each other. At this time, the first and second fixed arms can be interference-fitted with the fixing hole 118, and the limiting block abuts against the surface of the fixing plate 112 away from the reflector 130, thereby fixing the fixing plate 112. This arrangement facilitates the fixing between the fixing plate 112 and the reflector 130.

[0132] Figure 27 is a schematic diagram of the connection between the antenna support and the reflector in the antenna structure provided in this embodiment. Referring to Figure 27, in some examples, the feed component 140 includes a conductive post 167 connected to the reflector 130. The conductive post 167 is coupled to the feed line 121 and is used to receive radio frequency signals. With this configuration, the conductive post 167 can be used to fix the fixing plate 112 and the reflector 130, and at the same time, it can couple signals to the feed line 121, simplifying the antenna structure.

[0133] In the above implementation, the conductive post 167 can be integrated with the antenna bracket 110. It is understood that the conductive post 167 may include a portion of the dielectric substrate 111 and a conductive sidewall located on the outer side of the dielectric substrate 111. One end of the conductive sidewall is connected to the feed line 121, and the other end is used to receive radio frequency signals. Of course, in other implementations, the conductive post 167 can also be connected to the fixing plate 112 by adhesive bonding, bolt connection, snap-fitting, etc., and this application embodiment does not impose any limitations on this.

[0134] In the implementation of the dielectric plate 111 including the foamed plate, the conductive post 167 can be formed by extruding the dielectric plate 111. The extruded dielectric plate 111 has greater strength, which can improve the connection force between the fixing plate 112 and the reflector 130.

[0135] In the above implementation, the antenna structure may further include a circuit board 160. The circuit board 160 may be disposed on the side of the reflector 130 opposite to the fixed plate 112. The conductive post 167 may pass through the circuit board 160 and be soldered to the circuit board 160. Correspondingly, the phase shifter, filter, and combiner may all be disposed on the circuit board 160, so that the electrical connection between the phase shifter and the conductive post 167 can be realized through the lines on the circuit board 160.

[0136] In the implementation of the feed element 140 including the connector 143, a recess 119 may be provided on the fixing plate 112, and the connector 143 may be connected to the recess 119. Part of the connector 143 may be located within the recess 119 to facilitate miniaturization of the antenna structure. In the implementation of the dielectric substrate 111 as a foamed board, the recess 119 may be formed by extruding the fixing plate 112. The extruded foamed board has greater strength, which can prevent deformation of the foamed board in contact with the connector 143.

[0137] Figure 28 is a schematic diagram of the structure of the active antenna unit provided in the embodiment of this application. Please refer to Figure 28. The embodiment of this application also provides an active antenna unit (AUU), which includes a radio frequency device 30 and the antenna structure 10 in the above embodiment. The radio frequency device 30 is integrated into the antenna structure 10, that is, the radio frequency device 30 is integrated on the antenna structure 10. For example, the radio frequency device 30 can be disposed on the fixing plate 112 or the reflector 130 as shown in Figure 3, or the radio frequency device 30 can be disposed in the housing of the antenna structure 10. The radio frequency device 30 is coupled to the first feed element 168 and the second feed element 169. The radio frequency device 30 is used for transmitting and receiving radio frequency signals.

[0138] For example, a radio frequency device may include a remote radio unit (RRU) that can transmit and receive radio frequency signals.

[0139] Understandably, the radio frequency device 30 is integrated into the antenna structure 10, which facilitates the miniaturization and weight reduction of the active antenna unit. At the same time, it eliminates the need to connect the antenna structure 10 and the radio frequency device 30 via a coaxial cable, thereby reducing the transmission loss of radio frequency signals.
