Title:
ANTENNA AND CORRUGATED HORN FEED SOURCE THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/161718
Kind Code:
A1
Abstract:
An antenna and a corrugated horn feed source thereof. The corrugated horn feed source comprises a mode convertor, wherein the inner wall of the mode converter is provided with a plurality of excitation films, and the plurality of excitation films are located on the same aperture plane and are configured to excite a higher-order mode. At an aperture of the mode convertor, the relative amplitudes and the relative phases of the higher-order mode and a main mode satisfy a pre-set relationship. The technical solution reduces the cross polarization level of asymmetrical planes of a single-offset parabolic antenna by introducing a higher-order mode which is undesirable ordinarily, thereby effectively improving the cross polarization performance of the single-offset parabolic antenna.
