摘　　要：首先介绍了双T印刷天线,具有双频带、宽频带等优点,将优化后的双T天线印制在FR_4介质板上,对主要影响天线性能指标的接地板大小、电感加载、分集角度参数做了分析,最后设计出满足802.11 a/g协议的分集45°双T印刷天线,将天线集成到无线网卡上,经过实际测试满足设计要求。Firstly, the double-T printed antenna was introduced . Then in terms of the advantage of dual-band and broadband, the antenna was optimized and fabricated in FR_4 substrate. The size of ground, inductance and the Polarization- Diversity＇s degree which influence the antenna ＇ s performance were analyzed and designed. Finally, the polarization-diversity 45 degree Antenna which satisfied 802.11 a/g＇s protocol were developed, the tested results meet requirements.
