AI Technical Summary
Technical Problem
Traditional waveguide feed networks are large in size, making it difficult to meet the miniaturization requirements of next-generation satellite communication equipment.
Method used
The design employs a structure consisting of a first rectangular waveguide segment, a U-shaped waveguide segment, a circular waveguide, and an orthogonal mode coupler to form a compact Ku signal transmission channel. The symmetrically arranged U-shaped waveguide segments cancel out interference signals, and the overall size is reduced by combining this with the design of the Ka signal transmission channel.
Benefits of technology
A compact design of the waveguide feed network was achieved, reducing its size while improving the signal isolation and anti-interference capability of Ku signals.

Abstract
The present disclosure provides a waveguide feed structure. The waveguide feed structure comprises a first rectangular waveguide section, two first U-shaped waveguide sections, a circular waveguide, two second U-shaped waveguide sections and a second rectangular waveguide section; the first rectangular waveguide section is in communication with the first ends of the two first U-shaped waveguide sections, and the two first U-shaped waveguide sections are symmetric about the center line of the first rectangular waveguide section; the lower side of the circular waveguide is provided with an orthogonal mode coupler, the first end and the third end of the orthogonal mode coupler are in communication with the second ends of the two first U-shaped waveguide sections respectively; the waveguide extension direction of the first rectangular waveguide section is the same as that of the circular waveguide. The present disclosure can reduce the size of the waveguide feed network.
