Title:
FLAT-PANEL PASSIVE PHASED ARRAY FEED NETWORK LINE SOURCE
Document Type and Number:
WIPO Patent Application WO/2020/006805
Kind Code:
A1
Abstract:
Provided is a flat-panel passive phased array feed network line source. The flat-panel passive phased array feed network line source comprises a power splitter with multiple ports, a plurality of polarization transformers matching the power splitter in terms of the number of ports, and a power synthesizer connected in sequence, wherein the polarization transformer is composed of an input end waveguide and an output end waveguide connected through a cavity, such that a horizontal polarization wave enters the cavity through the input end waveguide, and is then output by the output end waveguide to a flat-panel waveguide after being rotationally polarized into a vertical polarization wave. The present invention does not require a polarization rotator, integrates the advantages of an E-plane waveguide and an H-plane waveguide, and has the characteristics of a compact structure, a large bandwidth, and being easy and convenient to design and manufacture.
