Research on Automatic Polarization Adjustment Technology of Satellite Antenna

Abstract

Satellite antennas that work with linear polarization need to be adjusted for polarization. According to the theory that any polarized wave can be synthesized by two orthogonal linear polarized waves in space, a method of automatic polarization adjustment is proposed. The method achieves automatic polarization adjustment by controlling the amplitude ratio of two orthogonal linearly polarized waves. This paper discusses the principle of automatic polarization adjustment, gives the method of automatic polarization adjustment which can be used in engineering, and verifies the veracity of this method through the actual measurement.
