Abstract

The invention relates to a phase shifter assembly and a base station antenna. The phase shifter assembly includes at least two coupling sheets; each coupling sheet includes a coupling line; a feed network includes at least two radiation output units in mutually electrical connection; the radiation output units and the coupling sheets are in corresponding arrangement and are same in quantity; eachradiation output unit includes a phase shifter line, a power divider line and a radiation output end; the phase shifter lines are connected to the coupling lines of the corresponding coupling sheets and can move phases; the power divider lines are electrically connected to the phase shifter lines and the radiation output ends; and the radiation output ends are used for electrically connecting radiation units. Each radiation unit of the base station antenna is corresponding to a phase shift function unit which can independently perform phase changing, so that phase changing can be independentlyperformed on each radiation unit, and therefore, the phase shift flexibility of the base station antenna can be enhanced.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to a phase shifter assembly and a base station antenna. Background technique [0002] In mobile communication network coverage, base station antenna is one of the key devices for optimizing network coverage. Traditional base station antennas typically have multiple radiating elements. The phase-shifting process of each radiating element is centralized and inflexible, which makes it difficult to optimize and debug the antenna. For example, in the application process of the base station antenna, phase shift is required, and the phase shift will affect the pattern. The pattern affects the radiation coverage of the antenna. Due to the centralized and inflexible phase-shifting process of traditional base station antennas, it is difficult to correct the pattern, thus affecting the antenna coverage effect. Contents of the invention [0003] Based on this, it is necessary t...
