BROADBAND PHASE SHIFTER AND BROADBAND BEAM-FORMING NETWORK

摘要

Provided are a broadband phase shifter and a broadband beam-forming network. The broadband phase shifter comprises a dielectric material board, a ground board and a micro-strip transmission line, wherein the ground board and the micro-strip transmission line are respectively located at the two sides of the dielectric material board, the ground board is grounded, and the two ends of the micro-strip transmission line are an input port and an output port of the broadband phase shifter, respectively. The micro-strip transmission line comprises at least one open-circuit branch or short-circuit branch. The broadband phase shifter and the broadband beam-forming network provided in the embodiments of the present invention are used for realizing the broadband of a phase shifter and the broadband of a beam forming network.
