摘要
Abstract
Polarization mismatch due to environmental factors including the attitude variation of carrier, rain-fading and multipath effect etc., usually results in poor quality of communication or even being unable to communicate for mobile satellite communication antenna. For resolving the problem, based on analysis and research on polarization, a technology of electrical polarization adjustment is proposed to realize polarization calibration. This technology can adjust polarization state in real time by controlling the amplitude and phase of a pair of orthogonal linear wave, which makes the polarization states of transmitting and receiving antennas match well, and ensures obtaining the maximum electromagnetic energy and improves the quality of communication. Experiment results indicate that the cross polarization isolation can reach up to 30dB for on-the-move antenna with an equivalent diameter of 0.6m at Ku band. Therefore, it can meet the requirements of satellite communication.关键词
