| Abstract: | A novel UHF RFID tag antenna with broadband characteristic is presented. The structures of T-matching network and double symmetrical radiating patches shorted to the ground plane are employed. The measured half-power bandwidth of the proposed antenna is 12.9% and it covers two major frequency bands. The maximum readable distance of the tag achieved 6.5 m in the RFID bands for North America and Europe. All the results show that the proposed antenna can work not only in air but also on metallic objects in the North America and Europe UHF RFID band. |
