A kind of phase shifter and base station antenna

Abstract

The invention relates to the field of mobile communication, and discloses a phase shifter and a base station antenna, wherein the phase shifter includes a phase shifter assembly, the phase shifter assembly includes a base plate and a sliding piece rotatably connected to the base plate, and the phase shifter assembly also includes a fixed Clip, the fixed clip is located on the side of the slide away from the substrate and the fixed clip is integrally connected to the substrate at the first end and the first end of the slide. The second end of the fixed clip is provided with a U-shaped groove, and the side of the substrate is inserted into the U In the groove, the second end of the sliding piece passes through the groove bottom of the U-shaped groove, and a supporting structure is arranged between the fixing clip and the sliding piece. In the phase shifter and base station antenna provided by the present invention, a U-shaped groove is arranged at the second end of the fixing clip to buckle the sliding piece and the substrate together, which is beneficial to improving the stability of the relative position between the sliding piece and the substrate, and further A supporting structure is set between the fixing clip and the sliding piece to press and limit the sliding piece, which is beneficial to avoid the problem of uneven gap between the sliding piece and the substrate during the rotation process, thereby ensuring stable performance of the phase shifter.

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...
