Abstract

The invention relates to the field of mobile communication, and discloses a phase shifter and a base station antenna. The phase shifter comprises a phase shifter assembly. The phase shifter assembly comprises a substrate and a sliding sheet rotatably connected to the substrate. The phase shifter assembly further comprises a fixing clamp. The fixing clamp is located on the side, away from the substrate, of the sliding sheet, the first end of the fixing clamp and the first end of the sliding sheet are integrally and rotationally connected to the substrate; and a U-shaped groove is formed in thesecond end of the fixing clamp, the side edge of the substrate is inserted into the U-shaped groove, the second end of the sliding sheet penetrates out of the bottom of the U-shaped groove, and a supporting structure is arranged between the fixing clamp and the sliding sheet. According to the phase shifter and the base station antenna, the U-shaped groove is formed in the second end of the fixingclamp to buckle the sliding sheet and the substrate together, so that the stability of the relative position between the sliding sheet and the substrate is improved; the supporting structure is further arranged between the fixing clamp and the sliding sheet to abut against and limit the sliding sheet, so that the problem that the gap between the sliding sheet and the substrate is uneven in the rotating process of the sliding sheet is solved, and the stable performance of the phase shifter can be guaranteed.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a phase shifter and a base station antenna. Background technique [0002] As the final control terminal of the mobile communication network, the antenna of the communication base station makes the final adjustment to the network provided to the user. The electric downtilt function of the electric adjustable antenna can meet the needs of the same type of antenna in different use areas and different communication load areas, and realize remote control and adjustment of the downtilt angle, so as to provide greater network capacity, reduce communication interference, and reduce labor costs. . [0003] As a key component of the electronically adjustable base station antenna, the phase shifter can change the antenna pattern by changing the phase of the signal arriving at the antenna, and realize continuous adjustment of the downtilt of the base station antenna beam. The widely use...
