Abstract

The invention provides a waveguide antenna. The waveguide antenna comprises an antenna body, a waveguide tube, a duplex duplexer, an emission polarizer and an electric modulation phase shifter, wherein the waveguide tube is arranged on the antenna body, one end of the waveguide tube is connected with the antenna body, and the other end of the waveguide tube is connected with the duplex duplexer; the duplex duplexer is located on the antenna body and is connected with the two polarization ports of the antenna body through the waveguide tube; the emission polarizer is located on the antenna body, and the emission polarizer is used for decomposing the emission signal into an emission horizontal signal and an emission vertical signal; the electric modulation phase shifter is arranged on the antenna body, an input port of the electric modulation phase shifter is connected with an output port of the emission polarizer, and an output port of the electric modulation phase shifter is connectedwith an input port of the duplex duplexer; a transmitting horizontal signal and a transmitting vertical signal enter the duplex duplexer through the electrically controlled phase shifter, and the electrically controlled phase shifter is used for carrying out phase matching on the transmitting horizontal signal and the transmitting vertical signal. 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...
