【Abstract】 A novel planar inverted-F antenna is proposed.Triple bands of RFID(915 MHz)/GPS (1575.42 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 on antenna characteristics are investigated.Simulation results are obtained by using HFSS V10 software,and compared with experimental results,with good agreement.更多还原
