Abstract

The invention relates to the technical field of a mobile communication base station antenna, aims to solve problems that processing difficulty increases because of small sizes of chambers and designing chambers in different sizes are required by phase shifters in different frequency bands existing in ultrahigh frequency phase shifters in the prior art and provides a phase shifter. The phase shifter comprises a rectangular chamber with two end openings, a power division feed network unit fixedly mounted in the rectangular chamber, two medium moving sheets arranged in the rectangular chamber, and a pull rod fixedly connected with the two medium moving sheets, wherein four transverse tail ends of the medium moving sheets are provided with direction holes, a side wall of the rectangular chamber is provided with multiple sets of openings used for eliminating resonance, and every two openings are arranged in parallel. The phase shifter is advantaged in that the side wall of the rectangular chamber is provided with the rectangular openings in different sizes, the higher mode appearance environment is broken by the openings, and a problem of prominent system resonance existing in an ultrahigh frequency micro phase shifter is solved.

Description

technical field [0001] The invention relates to the technical field of mobile communication base station antennas, in particular to a phase shifter and a base station antenna. Background technique [0002] With the rapid development of mobile communication technology, the electrical and mechanical performance requirements of base station antennas are getting higher and higher. The smart electronically adjustable antenna is a base station antenna that uses electronic methods to adjust the downtilt angle of the beam. In order to take into account co-channel interference and cell coverage, beamforming is usually performed on the vertical pattern of the antenna. The method of realizing beamforming is to optimize and adjust the feed amplitude distribution and phase distribution of each radiating element. The steering device is the key component to realize this function. [0003] At present, the working frequency band of the dielectric phase shifter is mainly concentrated in 1....
