[0037] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] With the development of wireless communication technology, in mobile communication technology, it is necessary to adjust the radiation angle of the base station antenna to cover different mobile communication areas. The antenna introduces a phase shifter device to adjust the antenna phase and thus adjust the antenna electrical downtilt angle. The adjustable phase antenna has a huge advantage in use relative to the fixed tilt antenna, and can quickly and conveniently adjust the electrical downtilt angle, thereby optimizing signal coverage.

[0039] However, with the popularization and promotion of multi-frequency electrically steerable antennas, the antenna frequency bands need to be continuously increased in the limited space of the antenna cover, resulting in increasingly cramped internal space of the antenna, making it difficult to assemble and repair the phase shifter.

[0040] Therefore, the embodiment of the present application proposes a phase shifter with a compact overall structure, reduced volume, convenient assembly, performance debugging and maintenance, and capable of meeting the requirements of multi-frequency antennas for small-size phase shifters.

[0041] See also Figure 1 , Figure 7 and Fig. 9As shown, the embodiment of the present application proposes a phase shifter 100, including a support assembly 10 and a phase shift assembly 20 installed on the support assembly 10, and the phase shift assembly 20 includes a first circuit board 21, a second circuit board 22, a first scribe 23, a second scribe 24 and a connector 25. The first circuit board 21 is provided with a first solder pad 211 for connecting the first cable 200, and the second circuit board 22 is provided with a second solder pad 221 for connecting the second cable 300, and the second circuit board 22 is stacked with the first circuit board 21. The first scribe 23 is rotatably arranged on the side of the first circuit board 21 facing away from the second circuit board 22, and the second scribe 24 is rotatably arranged on the side of the second circuit board 22 facing away from the first circuit board 21. The connector 25 is used to connect the first scribe 23 and the second scribe 24, and the connector 25 is configured to be able to receive an applied force, and the applied force here can be an externally applied driving force to drive the first scribe 23 and the second scribe 24 to rotate, so as to adjust the downtilt angle of the antenna. The first circuit board 21 and the second circuit board 22 are located on the same side of the support assembly 10 , and the first solder pad 211 is located on the side of the first circuit board 21 facing away from the support assembly 10 , and the second solder pad 221 is located on the side of the second circuit board 22 facing away from the support assembly 10 .

[0042] The phase shifter 100 provided in the embodiment of the present application sets the first circuit board 21 and the second circuit board 22 on the same side of the support assembly 10, that is, the first circuit board 21 and the second circuit board 22 can be both set on the upper side of the support assembly 10, at this time, the support assembly 10 plays a bearing and supporting role, and the first circuit board 21 and the second circuit board 22 are stacked and installed on the upper side of the support assembly 10 as a whole through the connector 25. At the same time, the first pad 211 is set on the side of the first circuit board 21 facing away from the support assembly 10, and the second pad 221 is set on the side of the second circuit board 22 facing away from the support assembly 10, that is, the first pad 211 and the second pad 221 can be both set upward, so that the overall structure is compact, the volume can be minimized, and the convenience of operation can be ensured, and assembly, performance debugging and maintenance are convenient.

[0043] Exemplarily, a first conductive circuit is provided on the side of the first scribe 23 opposite to the first circuit board 21 and coupled to the first circuit board 21, a plurality of second conductive circuits are provided on the side of the first circuit board 21 opposite to the first scribe 23 and coupled to the first scribe 23, which are concentrically arranged, have proportional radii and are arc-shaped, and the first scribe 23 rotates relative to the first circuit board 21 around the axis where the center of the second conductive circuit is located; a third conductive circuit is provided on the side of the second scribe 24 opposite to the second circuit board 22 and coupled to the second circuit board 22, a plurality of fourth conductive circuits are provided on the side of the second circuit board 22 opposite to the second scribe 24 and coupled to the second scribe 24, which are concentrically arranged, have proportional radii and are arc-shaped, and the second scribe 24 rotates relative to the second circuit board 22 around the axis where the center of the fourth conductive circuit is located.

[0044] The second conductive circuit of the first circuit board 21 is arranged symmetrically, and the fourth conductive circuit of the second circuit board 22 is arranged symmetrically, and the two ends of the second conductive circuit and the fourth conductive circuit are electrically connected to the radiation unit of the antenna through the first cable 200 and the second cable 300 respectively, and one end of the first scriber 23 and the second scriber 24 relative to the rotation center is connected to the feed source through capacitive coupling. When the first conductive circuit is coupled with the second conductive circuit, the third conductive circuit is coupled with the fourth conductive circuit, and the first scriber 23 and the second scriber 24 are rotated relative to the first circuit board 21 and the second circuit board 22, the physical path length of the electromagnetic wave signal from the main feed source to each radiation unit changes with the rotation angle of the first scriber 23 and the second scriber 24, so as to change the phase of the electromagnetic wave signal, thereby realizing the adjustment of the downtilt angle of the antenna beam.

[0045] In some embodiments, Figure 7 As shown, the first pad 211 and the second pad 221 are staggered so that the first cable 200 and the second cable 300 are staggered, thereby making it convenient for users to assemble, debug and repair the first cable 200 and the second cable 300 from above.

[0046] In some embodiments, the first circuit board 21 is located between the second circuit board 22 and the support assembly 10, and the size of the first circuit board 21 is larger than that of the second circuit board 22. In this embodiment, the first circuit board 21 and the second circuit board 22 are set to have different sizes, and the first pad 211 and the second pad 221 can be staggered through the staggered design of the upper small and the lower large, so that the first cable 200 and the second cable 300 are both facing the upper side of the support assembly 10 during welding, which is convenient for the assembly, performance debugging and maintenance of the phase shifter 100, and at the same time, the size of the phase shifter 100 is compressed, which can minimize the volume and ensure the convenience of operation.

[0047] In some embodiments, Figure 8 and Fig. 9As shown, the phase shifting assembly 20 further includes an isolation plate 26, and the isolation plate 26 is closely attached between the first circuit board 21 and the second circuit board 22. In the embodiment of the present application, the first circuit board 21 and the second circuit board 22 are attached to opposite sides of the isolation plate 26, and the isolation plate 26 can be made of a metal material or a non-metallic material with a metalized surface, which can prevent signal interference between the first circuit board 21 and the second circuit board 22 on the one hand, and can improve the overall rigidity of the phase shifter 100 and prevent deformation on the other hand.

[0048] In some embodiments, Figure 7-Figure 9 As shown, the phase shifting assembly 20 further includes a rotating shaft 27, which is disposed through the first circuit board 21 and the second circuit board 22. The rotating shaft 27 has a first end 271 and a second end 272 opposite to each other. The first scriber 23 is rotatably connected to the first end 271, and the second scriber 24 is rotatably connected to the second end 272, so that the connecting member 25 can drive the first scriber 23 and the second scriber 24 to rotate within a preset range with the rotating shaft 27 as the center. In the embodiment of the present application, the preset range can be set according to the rotation range required for the actual application. The first scriber 23 and the second scriber 24 are assembled through the rotating shaft 27 and the connecting member 25 to form a connection rotation structure with the rotating shaft 27 as the center. When the end of the connecting member 25 for receiving the force is toggled, the first scriber 23 and the second scriber 24 will rotate with the rotating shaft 27 as the center. Exemplarily, the rotating shaft 27 can be realized by rivets, which has a simple structure and is easy to assemble. The setting of the rotating shaft 27 can facilitate the rotation of the first scriber 23 and the second scriber 24, thereby realizing the adjustment of the downtilt angle of the antenna.

[0049] Exemplarily, the rotation axis 27 extends along the height direction of the phase shifter 100 , and the planes where the rotation tracks of the first scribing blade 23 and the second scribing blade 24 are located are perpendicular to the height direction of the phase shifter 100 .

[0050] In some embodiments, Figure 8 As shown, the connector 25 is configured to provide a force to the first scribe 23 and the second scribe 24, where the force can be the elastic force of the connector 25 itself, so that the first scribe 23 and the second scribe 24 have a relative force to clamp the first circuit board 21 and the second circuit board 22. In this embodiment, the connector 25 is configured to be able to apply a force to clamp the first circuit board 21 and the second circuit board 22 through the first scribe 23 and the second scribe 24, so that the performance of the phase shifter 100 is stable.

[0051] In some embodiments, Figure 8 and Fig.10As shown, the connecting member 25 includes a first clamping portion 251, a second clamping portion 252 and a force-bearing portion 253. The first clamping portion 251 and the second clamping portion 252 are arranged opposite to each other and connected by the force-bearing portion 253 to form a C-shaped clamp. The first clamping portion 251 and the second clamping portion 252 are respectively used to abut against the opposite sides of the first scribe 23 and the second scribe 24, so as to clamp the first circuit board 21 and the second circuit board 22 through the first scribe 23 and the second scribe 24. The force-bearing portion 253 is used to receive a driving force provided by the outside to drive the first scribe 23 and the second scribe 24 to rotate through the first clamping portion 251 and the second clamping portion 252. The C-shaped clamp can be made of plastic material, and its own plastic elasticity is used to form a positive pressure to clamp the first scribe 23, the second scribe 24, the first circuit board 21 and the second circuit board 22 toward the middle.

[0052] Alternatively, if Fig. 9 As shown, the connector 25 may also be provided with an elastic compression spring 254, the second end 272 of the rotating shaft 27 is provided with a blocking portion (when the rotating shaft 27 is a rivet, the end with a cap forms the blocking portion), and the first end 271 of the rotating shaft 27 is connected to the elastic compression spring 254, so that the C-type clamp and the elastic compression spring 254 cooperate to clamp the first circuit board 21 and the second circuit board 22.

[0053] In some embodiments, Figure 1-Figure 2 , Figure 11-Figure 12 As shown, the support assembly 10 includes a base 11 and a transmission structure 12, the phase shift assembly 20 is mounted on the base 11, a mounting position 111 is provided on the base 11, the transmission structure 12 is slidably connected to the mounting position 111, the transmission structure 12 interferes with the connecting member 25, and is used to connect the driving structure, so as to drive the connecting member 25 to rotate under the action of the driving structure, thereby driving the first scriber 23 and the second scriber 24 to rotate. In the embodiment of the present application, the base 11 can be mounted to the reflector 400 of the antenna to play a bearing and supporting role, the transmission structure 12 can be connected to the driving structure, and the driving structure can be a device such as a motor that can provide a driving force. The driving structure can realize the driving transmission structure 12 to slide at the mounting position 111, thereby driving the first scriber 23 and the second scriber 24 to rotate through the connecting member 25, so as to adjust the downtilt angle of the antenna.

[0054] In some embodiments, Figure 7-Figure 14As shown, the connecting member 25 is provided with a guide column 255, and the transmission structure 12 includes a guide member 121 and a pulling member 122. The guide member 121 is used to connect the driving structure so as to move linearly under the action of the driving structure. The pulling member 122 is connected to the guide member 121, and the pulling member 122 is provided with a movable groove 1221 for the guide column 255 to pass through. The pulling member 122 is used to move with the guide member 121, and the guide column 255 cooperates with the movable groove 1221 to drive the connecting member 25 to rotate, thereby driving the first scriber 23 and the second scriber 24 to rotate. In the embodiment of the present application, the guide member 121 can move along the front-to-back direction of the phase shifter 100 under the drive of the driving structure. The guide column 255 is arranged on the force-bearing portion 253 of the connecting member 25 and extends in the direction away from the supporting assembly 10, that is, extends upward. The guide column 255 is arranged as a portion of the connecting member 25 for receiving the force. The guide column 255 can be movably inserted into the movable groove 1221 of the pulling member 122 so as to interfere with the movable groove 1221. The structure is simple and easy to implement, so that the pulling member 122 can be driven by the guide member 121 to drive the connecting member 25 to move through the interference between the guide column 255 and the movable groove 1221, so as to drive the first scriber 23 and the second scriber 24 to swing back and forth in a circle with the rotating shaft 27 as the center, so as to adjust the downtilt angle of the antenna.

[0055] In some embodiments, Figure 7-Figure 10 As shown, a first limiting column 256 and a second limiting column 257 can be provided on the force-bearing portion 253 of the connecting member 25, the first limiting column 256 is provided on the side of the force-bearing portion 253 facing the supporting assembly 10, that is, the lower side of the force-bearing portion 253, a first limiting hole 231 opposite to the first limiting column 256 is provided on the first scriber 23, the second limiting column 257 is provided on the side of the force-bearing portion 253 facing away from the supporting assembly 10, that is, the upper side of the force-bearing portion 253, and a second limiting hole 231 opposite to the second limiting column 257 is provided on the second scriber 24. The first limiting post 256 is inserted into the first limiting hole 231 and the second limiting post 257 is inserted into the second limiting hole 241 during installation, thereby assembling the first scriber 23, the second scriber 24 and the connector 25 into one body. At the same time, the connector 25 provides long-term positive pressure to the first scriber 23 and the second scriber 24 through interference fit during installation, thereby ensuring that the first scriber 23 and the second scriber 24 can clamp the first circuit board 21, the second circuit board 22 and the isolation plate 26 therebetween, thereby ensuring stable performance.

[0056] For example, Fig. 9 and Fig.10As shown, two second limiting columns 257 can be provided, and the two second limiting columns 257 are arranged on both sides of the guide column 255. The second scriber 24 is provided with two second limiting holes 241 corresponding to the two second limiting columns 257, and the first limiting column 256 is arranged opposite to the guide column 255. The above-mentioned structural arrangement is stable, so that the force-bearing part 253 can drive the first scriber 23 and the second scriber 24 to rotate at the same time.

[0057] In some embodiments, the guide member 121 and the pulling member 122 can be integrally formed to provide a stable structure, or they can be connected in parts and assembled together after being processed separately to facilitate disassembly, assembly and subsequent maintenance.

[0058] In some embodiments, Fig.12 and Fig.13 As shown, a plurality of mounting positions 111 are provided on the base 11, and the plurality of mounting positions 111 are arranged side by side along a first direction, and the first direction is a horizontal direction and is perpendicular to the moving direction of the transmission structure 12. In the embodiment of the present application, when the moving direction of the transmission structure 12 is the front-rear direction of the phase shifter 100, the first direction is the left-right direction of the phase shifter 100, and more than two mounting positions 111 can be provided, for example, two, three, four or more. By providing a plurality of mounting positions 111, the transmission structure 12 can be installed at the mounting positions 111 at appropriate positions according to the size of the phase shifting component 20. When the size of the phase shifting component 20 is small, it can be installed at the mounting position 111 close to the inner side of the base 11, and when the size of the phase shifting component 20 is large, it can be installed at the mounting position 111 close to the outer side of the base 11, so that it can adapt to the installation and use of phase shifting components 20 of different types and sizes, and improve the versatility of the material.

[0059] Alternatively, if Figure 11-Figure 12 As shown, a detachable mounting buckle 112 is provided on the base 11, and the mounting buckle 112 has a through groove running through the front and back. The mounting buckle 112 is installed corresponding to the mounting position 111 to stabilize the transmission structure 12 so that the transmission structure 12 can stably slide on the mounting position 111. The guide member 121 is movably penetrated in the through groove to guide the guide member 121 to move forward and backward under the drive of the driving structure, so as to drive the pulling member 122 to move forward and backward. At this time, the movable groove 1221 of the pulling member 122 will interfere with the guide column 255 of the connecting member 25, so as to drive the connecting member 25 to rotate by moving the guide column 255, thereby driving the first scriber 23 and the second scriber 24 to rotate, so as to adjust the downward tilt angle of the antenna.

[0060] Exemplarily, a plurality of mounting buckles 112 arranged side by side along the first direction may be provided to correspond to the plurality of mounting positions 111 . The plurality of mounting buckles 112 may be provided separately or integrally formed, that is, one mounting buckle 112 may cover the plurality of mounting positions 111 .

[0061] For example, along the moving direction of the transmission structure 12, a plurality of mounting buckles 112 may be provided, such as two, three or four, so as to prevent the transmission structure 12 from shifting in position and shaking in other directions, thereby improving stability.

[0062] In some embodiments, Figure 11-13 As shown, the base 11 is provided with a wire clamping structure 113 to fix the first cable 200 and the second cable 300. In the embodiment of the present application, the wire clamping structure 113 can be provided with a plurality of clamping grooves corresponding to the first cable 200 and the second cable 300 along the first direction to fix the first cable 200 and the second cable 300 to improve the stability of the antenna.

[0063] For example, Figure 7 and Fig.11 As shown, the first circuit board 21 is provided with a first solder pad 211 on both sides of the second direction, and the second circuit board 22 is provided with a second solder pad 221 on both sides of the second direction, so the first circuit board 21 is connected with a first cable 200 on both sides of the second direction, and the second circuit board 22 is connected with a second cable 300 on both sides of the second direction, and the second direction is the moving direction of the transmission structure 12. The base 11 is provided with a clamping structure 113 on both sides of the second direction corresponding to the first cable 200 and the second cable 300 on both sides, so as to fix the first cable 200 and the second cable 300 on both sides of the second direction, so as to improve the stability of the antenna.

[0064] In some embodiments, Figure 3 and 12 As shown, the phase shifter 100 further includes a first bracket 30 and a second bracket 40 mounted on both sides of the base 11 in the second direction, and the second direction is the moving direction of the transmission structure 12. In the embodiment of the present application, the base 11 is used to support the phase shifting component 20, and plays a supporting and bearing role. The base 11 can be mounted on the reflector 400 of the antenna through the first bracket 30 and the second bracket 40.

[0065] In some embodiments, Figure 3-Figure 6 As shown, a supporting assembly 10 and a phase shifting assembly 20 are assembled to form a set of phase shifting modules 100a. The assembled phase shifting modules 100a are installed on the reflector 400 of the antenna. The structure is compact and convenient for assembly and subsequent maintenance.

[0066] Alternatively, if Figure 3 and Figure 4As shown, the number of phase shifting modules 100a can be one, and the support assembly 10 is used to be mounted on the reflector 400 of the antenna. In this embodiment, the base 11 is mounted on the reflector 400 of the antenna through the first bracket 30 and the second bracket 40, and the transmission structure 12 and the phase shifting assembly 20 are mounted on the base 11, which can be fixed by rivets, screws, etc., so as to realize the installation and use of a single set of phase shifting modules 100a.

[0067] Optionally, the number of the phase shift modules 100a may also be multiple, such as Figure 5 and Figure 6 As shown, the phase shifter 100 also includes a heightening bracket 50, which is connected to the supporting assembly 10, wherein the supporting assembly 10 of one phase shifting module 100a is used to be installed to the reflecting plate 400 of the antenna, and the remaining phase shifting modules 100a are stacked and installed along the height direction of the phase shifter 100 through the heightening bracket 50. Exemplarily, the bottom-layer raised bracket 50 can be installed on the two side edges of the second direction of the base 11 of the support assembly 10, or can be installed on the first bracket 30 and the second bracket 40. The bottom-layer group of phase shifting modules 100a is installed on the reflector 400 of the antenna through the first bracket 30 and the second bracket 40, and the raised bracket 50 is installed on the base 11. Then, the remaining phase shifting modules 100a are continued to be installed on the raised bracket 50 to achieve the superposition of multiple groups of phase shifting modules 100a. Each group of phase shifting modules 100a is supported on the front and back sides by at least two raised brackets 50. The raised brackets 50 are used for stacking and installation, which can not only meet the use of phase shifting modules 100a with multiple frequency bands and multiple outputs at the same time, but also the stacking setting has a height expansion function, and the phase shifting modules 100a can be stacked in the height direction as needed, so as to make full use of the space, have a compact structure, reduce the volume, effectively save antenna space, and achieve the sharing of multiple phase shifting modules 100a.

[0068] For example, Figure 3-Figure 6 , Figure 11-13 As shown, the base 11 may be provided with an installation interface 114 for snapping into the elevated bracket 50. When multiple sets of phase shifting modules 100a need to be installed, the lowest level elevated bracket 50 may be installed on the lowest level base 11 through the installation interface 114, and the remaining elevated brackets 50 may be installed in sequence on the base 11 of the corresponding level through the installation interface 114.

[0069] For example, Figure 6 As shown, the base 11 may be provided with a group of mounting interfaces 114 on both sides of the first direction, and each group of mounting interfaces 114 includes at least two mounting interfaces 114 spaced apart along the second direction, so that at least four elevated brackets 50 may be installed to balance the forces of the stacked phase shifting modules 100a and improve the structural stability.

[0070] In some usage scenarios, the phase shifter 100 of the embodiment of the present application can be used for base station antennas, especially for multi-frequency multi-port antennas. The phase shift component 20 adopts a staggered design, and the support component 10 can meet the use of phase shift components 20 of various frequency bands and various outputs through the setting of multiple mounting positions 111 and the pad bracket 50, which can effectively save material types and antenna system costs. At the same time, the miniaturized design can reduce the weight of the antenna, improve product reliability, and have good scalability, safety and reliability.

[0071] The embodiment of the present application further provides an antenna, comprising a reflector 400, a radiation unit and the above-mentioned phase shifter 100, wherein the radiation unit is disposed on one side of the reflector 400. The phase shifter 100 is disposed on the other side of the reflector 400, specifically, Figure 3-Figure 6 As shown, the supporting assembly 10 of the phase shifter 100 is mounted on the reflector 400, the first circuit board 21 of the phase shifter 100 is electrically connected to the radiation unit through the first cable 200, and the second circuit board 22 of the phase shifter 100 is electrically connected to the radiation unit through the second cable 300. Exemplarily, the antenna proposed in the embodiment of the present application can be a base station antenna, especially a multi-band multi-port antenna.
