摘要：

A planar broadband circular tag antenna operated at ultra-high frequency (UHF) band for radio-frequency identification (RFID) system is proposed. By adding a pair of T-arc-shaped strips and parasitic step strips, excitation of multi-resonant modes can approximate reach with the operating half-power band from 848 to 963 MHz, which covers the required bandwidth for worldwide UHF RFID (860-960 MHz) system. Moreover, the measured read distance of this design can reach 3.8 m, and exhibits good unidirectional radiation patterns in the X-Z and X-Yplanes.
