A Novel Broadband UHF RFID Tag Antenna Mountable on Metallic Surface

摘要：

A novel broadband UHF RFID tag antenna mountable on metallic surface is presented. The structures of T-matching network and double symmetrical radiating patches shorted ground plane are employed. The proposed antenna has a half power bandwidth of 11.4％ when placed in free air and covers two major segments of the UHF RFID band when mounted metallic surface. The proposed antenna also has good radiation characteristics and cross-polarization performances in both conditions. The results show that the proposed antenna can work not only in free air but also on metallic surface for UHF RFID band.
