Abstract

The application provides a waveguide antenna, including: an antenna body, a waveguide, a two-way duplexer, a transmitting polarizer and an electric phase shifter; the waveguide is arranged on the antenna body, and one end of the waveguide is connected to the antenna body , the other end of the waveguide is connected to the two-way duplexer; the two-way duplexer is located on the antenna body, and is connected to the two polarization ports of the antenna body through the waveguide; the transmitting polarizer is located on the antenna body, and the emitter The polarizer is used to decompose the transmitted signal into a horizontal signal and a vertical signal; the electric phase shifter is arranged on the antenna body, the input port of the electric phase shifter is connected with the output port of the transmitting polarizer, and the electric The output port of the output port is connected to the input port of the double-way duplexer; the transmitted horizontal signal and the transmitted vertical signal enter the double-way duplexer from the electric phase shifter, and the electric phase shifter is used to phase the transmitted horizontal signal and the transmitted vertical signal match. The polarization isolation performance of the dual-polarization waveguide array antenna can be improved.

Description

technical field [0001] The present application relates to the technical field of signal transmission, in particular to a waveguide antenna. Background technique [0002] At present, any linear polarization of the waveguide array antenna is synthesized by two signals of horizontal polarization and vertical polarization. When the polarization is synthesized, the phases of the two signals are required to be the same, otherwise the polarization isolation of the synthesized signal will be particularly poor. , does not meet the usage requirements. [0003] The waveguide horn array antenna is composed of waveguide horn array antenna surface, dual duplexer and polarizer, etc. During the design process, it is necessary to ensure the horizontal polarization of the waveguide horn array antenna surface, dual duplexer and polarizer In this case, the polarization isolation of any linearly polarized signal synthesized by the polarizer can meet the requirements. However, in actual process...
