本文对一种内置分集天线系统的相关系数特性与天线间距和入波分布的关系进行了数值分析，该分集天线系统包括安装在无线电箱两侧的两个平面倒f天线。研究发现，即使天线间距很小，相关系数也足够低。发现两个天线之间的相互耦合在获得低相关系数方面起着重要作用。结果表明，内置分集天线在有效增益方面具有良好的性能。计算结果与实验结果吻合较好。<<ETX>>
The authors present a numerical analysis of correlation coefficient characteristics with antenna separation and incoming wave distribution for a built-in diversity antenna system comprising two planar inverted-F antennas (PIFAs) mounted on both sides of the radio case. It was found that even small antenna separation yields a sufficiently low correlation coefficient. Mutual couplings between the two antennas were found to play a major role in obtaining low correlation coefficients. It was also found that the built-in diversity antennas have good performance in terms of effective gain. The calculated results were in fairly good agreement with experimental results.<<ETX>>
