Phase shifter, phase shifting assembly comprising phase shifter, and phase shifting feed network

Abstract

The utility model discloses a phase shifter, a phase shifting assembly comprising the phase shifter and a phase shifting feed network. The phase shifting feed network comprises a plurality of phase shifters, a plurality of power dividing units and a transmission unit, wherein the phase shifter comprises a suspended strip line structure formed by sequentially arranging a conductor shielding cover, a second dielectric plate, U-shaped coupling lines on the second dielectric plate, parallel coupling lines, a first dielectric plate where the parallel coupling lines are located and a metal ground in a stacked mode. The first dielectric plates of the phase shifters are arranged in a one-piece mode so as to form a one-piece dielectric plate; the power dividing units are arranged on the one-piece dielectric plate; the phase shifters are symmetrically arranged in two columns, the parallel coupling lines of the adjacent phase shifters in the single column are connected through the power dividing units; and the transmission unit is connected with the second dielectric plate of each phase shifter so as to drive the plurality of second dielectric plates to move, thereby enabling the U-shaped coupling lines to move relative to the parallel coupling lines, and realizing phase shifting of signals. The phase shifting feed network is a mixed phase shifting feed network comprising suspended strip lines and microstrip lines, thereby being capable of realizing phase shifting of an electrically adjustable antenna with a higher integration level, better expansibility and more excellent performance.
