摘要: In this paper, we compare different methods to determine correlation. First, did analytical study on correlation of two parallel dipoles. We present for calculation. addition, the effect source impedances is also studied. It found that these result in same correlation, and impedance matched embedded element gives smallest Then, compared determining correlations multi-port antennas from measurements. Wideband eleven antenna was used shown can be determined correctly either using radiation far field functions based anechoic chamber (AC) measurement (i.e., method), or cross-correlation definition reverberation (RC) RC method). Scattering parameters (S-parameter) only lossless S-parameter general lossy antenna, method most convenient use.
