Antenna diversity for UHF handportable radio
暂无分享,去创建一个
Theoretical and simulation studies have been undertaken to explain the experimentally-observed effect that the correlation between the signals obtained from closely-spaced antennas is smaller than that predicted by well-known theoretical models. When mutual coupling effects are significant, the correspondence between signal and field component correlation breaks down. Taking two parallel dipoles as an example, it is shown that useful diversity advantage can be obtained with separations of the order of 0.1λ.
