关于 Antenna Diversity

谁能讲讲antenna diversity是怎么定义的？
还有如果用两个天线，他们距离要保持多远呢？

Antenna diversity simply means using two or more antennas to get better received signal.The distance between antenna is depend on get diversity horizontal or vertical. For horizontal, the distance ~ 10 times of wavelength. For Horizontal, the distance ~ 6 times of wavelength.

我记得还有其他很多分集方式吧，比如说极化分集这些，不一定非要两天线隔开一定距离

我人为距离非关键,关键在于方向.

天线的分集有许多种方式，包括spatial diversity, Polarisation diversity, time diversity, frequency diversity and angle(beam) diversity.一般天线会采取多种分集方式结合。推荐看看‘Antenna Theory and Design, 2nd Edition (Hardcover)

建議兩隻天線距離相隔波長/2 較為安全
