摘要
本文研究了两种新型极化和方向图分集玻璃介质谐振器天线（DRA），均适用于三频段（2.4 GHz、5.2 GHz和5.8 GHz）无线保真（WiFi）应用。通过比较这两种分集DRA以及一种新的空间分集玻璃DRA，研究了哪种类型的分集天线最适合WiFi 路由器应用。同时，将这三种分集玻璃DRA还与商用空间分集单极子对进行了比较，以衡量玻璃DRA在WiFi 路由器应用中的性能。本文在极化分集天线中，提出了双端口馈电方案来激发不同的DRA模式。DRA模式的频率通过使用阶梯形DRA进行调谐。在方向图分集设计中，引入了堆叠DRA来拓宽锥形和宽边辐射模式的带宽。实验制作了这三种新型分集天线，并测量了三种分集玻璃天线和参考空间分集单极天线的误码率（BER），并对结果进行了比较和讨论。结果表明，极化分集全向DRA的误码率最为稳定。
