摘　　要：提出一种新型的平面倒F天线结构,该结构通过在矩形贴片上开L形和T形槽实现工作于RFID(915 MHz)/GPS(1 575.42 MHz)/WCDMA(2.1 GHz)的三频特性.该天线的3个电流路径共用一个馈电点,结构简单,容易制作,可以根据实际需要选择不同的频率点.使用HFSS V10进行仿真分析,实测结果和仿真结果比较吻合.A novel planar inverted-F antenna is proposed. Triple bands of RFID （915 MHz）/GPS （1 575.42 MHz）/WCDMA （2.1 GHz） are realized by etching L-shape and T-shape slots on a rectangular patch. The proposed antenna has simple structure and needs only one feed, therefore is easy to fabricate and adjust. According to application scenarios, it can work in different frequency bands. The effects of different parameters by using HFSS V10 software, on antenna characteristics are investigated. Simulation results are obtained and compared with experimental results, with good agreement .
