Structure-integrated circular polarization feed source

Abstract

The invention provides a structure-integrated circular polarization feed source. Circular polarization signal radiation is achieved through a structure-integrated design. The structure-integrated circular polarization feed source comprises an input waveguide as an input port of a microwave signal and a standard rectangular waveguide flange plate, an impedance conversion segment, a circular polarization segment and a horn radiator, wherein the impedance conversion segment is used for connecting the input waveguide and a circular waveguide of the circular polarization segment; a circular polarizer and an input electric field form an angular relationship of 45 degrees, so that an input linear polarization field is converted into a circular polarization field; and the horn radiator is used for transmitting a circular polarization signal into an external space. Therefore, circular polarization radiation is achieved by using the structure-integrated circular polarization feed source provided by the invention; various parts are of the structure-integrated design; the processing technology is easy to achieve; the reliability is high; and the structure-integrated circular polarization feed source can be used for mass production of array antenna feed source units.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to a feed source for structurally integrated design and radiating circularly polarized signals, in particular to a structurally integrated circularly polarized feed, which realizes circularly polarized signal radiation through structurally integrated design. Background technique [0002] In a high-gain phased array antenna, the antenna array consists of a large number of identically designed feed arrangements. In order to eliminate the loss caused by the alignment error of the linear polarization, the communication antenna generally adopts the circular polarization working mode, and the feed source needs to have the circular polarization radiation capability. Due to the large number of feed sources, in order to reduce the processing cost, a simple and reliable processing technology must be adopted to realize mass production. [0003] According to the implementation, the feed can be ...
