天线间的相关性怎么计算

问题 太宽泛了
相关性问题也就是阵列天线考虑到多点具体算法 找阵列天线书看看吧 。如果是独立的天线  相关性和天线的方向图  放置位置 极化方式等相关。

you can used S-parameters or rdaited fields from two antennas to calculate it if you are mentioning envelope correlation coefficients between two elements in MIMO /diversity systems.

那么对于mimo天线来说，相关性跟隔离有什么关系?

simply speaking, the larger the isolation, the larger that distance. this is because the mutual coupling between two elements weakens with the increase in distance between two antennas.
