Description

Technical Field

[0001] This application relates to the field of antennas, and more particularly to a phase shifter phase compensation assembly and antenna. Background Technology

[0002] In wireless communication systems, the radiation performance of base station antennas directly affects signal coverage quality and communication efficiency. As a core component of the antenna system, the phase shifter functions to achieve beam pointing control and sidelobe suppression by adjusting the phase of electromagnetic waves. Traditional cableless phase shifters consist of integrated, synchronously equidistant phase-shifting units, with each unit's output directly connected to the vibrator interface. While this design simplifies assembly, it reveals significant drawbacks in actual deployment: because the phase shifter is a fixed module, the amplitude and phase output to the vibrator may differ from the preset values ​​due to factors such as manufacturing process quality and material errors. Furthermore, due to the complex and variable environment of the antenna array, the vibrator is susceptible to electromagnetic influences from adjacent vibrators or the array itself, easily leading to impedance characteristic discrepancies. Since the amplitude and phase of the phase shifter cannot be adjusted at any time, when the amplitude and phase of the phase shifter and the impedance divergence of the vibrator coexist, the amplitude and phase of the radiated electromagnetic wave will deviate from the preset amplitude and phase, causing the main lobe of the beam to shift and causing abnormal fluctuations in the sidelobe level at different frequencies. This manifests as random shifts in the sidelobe position and uneven suppression strength, which seriously affects the controllability and stability of the antenna pattern, and consequently affects the coverage quality of the base station signal. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a phase shifter phase compensation combination device and antenna.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] This application provides:

[0006] A phase shifter phase compensation assembly includes:

[0007] A phase shifter, wherein the phase shifter has at least one connection port;

[0008] A circuit board is disposed at each of the connection ports and is connected to the phase shifter;

[0009] A matching medium, which is slidably disposed on the circuit board and is movable relative to the circuit board;

[0010] An oscillator assembly is connected to the circuit board, and the oscillator assembly is connected to the phase shifter via the circuit board.

[0011] Furthermore, a connector is provided at the connection port, and the phase shifter is connected to the circuit board through the connector.

[0012] Furthermore, the circuit board includes a dielectric layer, a circuit is provided on the side of the dielectric layer away from the phase shifter, and a ground layer is provided on the side of the dielectric layer facing the phase shifter. Clearance grooves are provided on the dielectric layer, the circuit, and the ground layer.

[0013] Furthermore, at least one through slot is provided through the surface of the matching medium parallel to the circuit board.

[0014] Furthermore, the through groove is rectangular, oblong, elliptical, or circular in shape.

[0015] Furthermore, the oscillator assembly includes a base, and a plurality of radiators are provided at the end of the base away from the phase shifter. Two feed plates connected to the circuit board are also mounted on the base.

[0016] Furthermore, the base has multiple mounting holes, the power supply plate passes through the mounting holes and connects to the circuit board, and the radiator has a through-hole groove.

[0017] Furthermore, the two feed plates are arranged in a cross shape.

[0018] Furthermore, the hollowed-out groove is rectangular, triangular, or circular in shape.

[0020] This application, by setting a slidingly adjustable matching medium and circuit board matching structure, can dynamically compensate for the phase shift caused by the impedance discretization of the oscillator assembly. By using the sliding of the matching medium relative to the circuit board to change the dielectric constant distribution of the electromagnetic wave transmission path, the phase output of the phase shifter to the oscillator assembly is compensated for phase, thereby maintaining the phase consistency of the electromagnetic waves radiated by each oscillator assembly, effectively suppressing the main lobe direction shift and abnormal fluctuations in the sidelobe level, and improving the linearity of the antenna pattern and the stability of sidelobe suppression.

[0040] Existing phase shifters typically employ an integrated fixed power supply network structure, with the phase shifting unit directly connected to the oscillator. While this simplifies the assembly process, it is easily affected by external factors and cannot be adjusted. To address this, this application sets a phase compensation device at each outlet of the phase shifter. Each outlet is compensated by the phase compensation device before being connected to the oscillator, thereby enabling individual phase adjustment of each oscillator.

[0041] This application provides a phase shifter phase compensation assembly, which includes a phase shifter 100, a circuit board 200, a matching medium 300, and an oscillator assembly 400. Specifically, the phase shifter 100 has at least one connection port 110, the circuit board 200 is disposed at each of the connection ports 110, the circuit board 200 is connected to the phase shifter 100, the matching medium 300 is slidably disposed on the circuit board 200, the matching medium 300 is movable relative to the circuit board 200, and the oscillator assembly 400 is connected to the circuit board 200 and is connected to the phase shifter 100 through the circuit board 200.

[0042] See Figure 1 and Figure 2 As shown, two phase shifters 100 are arranged side by side, and each phase shifter 100 has a connection port 110. The connection port 110 is connected to the internal power supply network of the phase shifter 100. In other words, the connection port 110 serves as a bypass function, facilitating the connection between the circuit board 200 and the internal power supply network of the phase shifter 100. When phase adjustment is required, phase compensation can be achieved by driving the matching medium 300, and then the phase-compensated signal is sent to the oscillator assembly 400 for transmission.

[0043] In some embodiments, regarding how to move the matching medium 300 to achieve phase adjustment, for example, the matching medium 300 can be moved linearly by means of a pull rod, and then the pull rod connected to the matching medium 300 can be moved by a linear drive device, thereby realizing the position movement of the matching medium 300 relative to the circuit board 200, that is, phase adjustment can be achieved. In practice, the linear drive device can be selected and used according to actual needs, and no specific limitation is made here.

[0044] In some embodiments, during the equipment commissioning process, the matching medium 300 can also be moved manually to achieve phase adjustment.

[0045] In this embodiment, the matching medium 300 mentioned above represents a dielectric material that has the function of changing the wavelength of electromagnetic waves in the medium. Examples include polytetrafluoroethylene, ceramic-filled polymers, aluminum nitride ceramics, etc. In practice, materials can be selected and used according to actual needs, and no specific restrictions are made here.

[0046] It should be noted that after the matching medium 300 adjusts the phase compensation, that is, when the matching medium 300 is in a specific position, the matching medium 300 and the phase shifter 100 can be fixed.

[0047] At least one through slot 310 is provided through the surface of the matching medium 300 that is parallel to the circuit board 200.

[0048] See Figure 1 , Figure 2 , Figure 5 As shown in the figure, in order to achieve phase tangency adjustment, at least one through slot 310 is formed through the matching medium 300. The impedance matching is adjusted by the through slot 310. By sliding the matching medium 300, the length of the circuit board 200 covering the matching medium 300 is changed to achieve the phase compensation effect.

[0049] In this embodiment, the size of the through slot 310 can be adjusted according to the frequency of the signal being transmitted, and there is no limitation on it here. The shape of the through slot 310 can also be designed as needed.

[0050] See Figure 3 As shown, Figure 3 The diagram shows the state of the phase shifter 100 with only one connection port 110, and the circuit board 200 and the matching medium 300 set at the connection port 110.

[0051] See Figure 4 As shown, Figure 4 The diagram shows the state of the phase shifter 100 having multiple connection ports 110, with a circuit board 200 and a matching medium 300 set at each connection port 110.

A clearance groove 240 is provided on the dielectric layer 210, the line 220 and the ground layer 230.

[0056] See Figure 7 As shown, in order to enable the line 220 to be electrically connected to the phase shifter 100, a clearance groove 240 is opened at the same position in the dielectric layer 210, the line 220 and the ground layer 230. The connector 120 passes through each clearance groove 240 and contacts the line 220. Specifically, the connector 120 passing through the clearance groove 240 can be connected to the line 220 by welding.

[0057] It is understood that the shape of the clearance groove 240 should be adapted to the shape of the connector 120 so that the connector 120 can be inserted into the clearance groove 240.

[0059] See Figures 8 to 10 As shown, the power supply plate 430 is connected to the circuit board 200. The power supply plate 430 then transmits the signal current from the circuit board 200 to the radiator 420. Finally, the radiator 420 converts the signal current into electromagnetic waves and radiates them into space. Alternatively, the radiator 420 receives electromagnetic waves in space and converts them into electrical signals, which are then transmitted to the circuit board 200 via the power supply plate 430.

In this embodiment, four mounting holes 411 are provided and are evenly distributed around the base 410. There are two power supply pieces 430, and each power supply piece 430 has two antennas of different lengths, which can be referred to as a long antenna and a short antenna. The long antenna of the power supply piece 430 passes through the mounting hole 411 and connects to the circuit board 200, while the short antenna of the power supply piece 430 extends into the mounting hole 411 in the opposite direction, thereby mounting the power supply piece 430. It can be understood that the two power supply pieces 430 are arranged in a cross shape.

[0062] Please continue reading. Figure 1 , Figures 8 to 10 As shown, in this embodiment, there are four radiators 420, and each radiator 420 is located at the position of each mounting hole 411.
