Abstract

In this paper, a novel broadband Tag antenna for ultra-high frequency (UHF) near-field and far-field radio-frequency identification (RFID) applications is presented. This antenna is printed on an Rogers RT/duroid 5880 substrate with an overall size of 68 × 19.7 × 0.787 mm. The simulated bandwidth of the proposed Tag antenna is more than 100 MHz (860-960 MHz), which can cover the entire UHF RFID band. The proposed structure can generate a strong and uniform H-field distribution in the region around the antenna. Measurements show that the antenna operating confirms good performance of Tag identification for near-field and far-field UHF RFID applications.
