Abstract

The present invention provides a horn antenna for realizing multiple polarizations, which includes: a horn antenna body, a polarizer, a waveguide transition, and a rotating mechanism for adjusting the relative angle between the polarizer and the waveguide transition. The horn antenna body, the polarizer, the rotating mechanism and the waveguide are connected in sequence. The beneficial effects of the present invention are: by designing the combined structure of the horn antenna body, the polarizer, the waveguide transition and the rotating mechanism for adjusting the relative angle between the polarizer and the waveguide transition, the waveguide transition and the waveguide transition are changed by the rotating mechanism. The relative angle between the polarizers can be changed to change the polarization characteristics of the electromagnetic wave inside the conical horn. efficiency.

Description

technical field [0001] The present invention relates to a horn antenna, in particular to a horn antenna that realizes multiple polarizations. Background technique [0002] Horn antennas are mainly used for antenna product testing, such as antenna far-field test systems, near-field test systems, etc., to calibrate the performance of the antenna product to be tested, including antenna gain, antenna pattern characteristics, antenna polarization characteristics, etc. [0003] In the test of antenna products, the horn antenna used for calibration should match the polarization of the antenna to be tested. For a fixed frequency band, the antenna to be tested may have multiple polarization forms. The common method is to prepare wire poles. There are at least three sets of horn antennas with different polarizations: polarization, left-hand circular polarization, and right-hand circular polarization. Another method is to realize different polarizations of the horn antenna by changing ...
