In this paper, an-ultra-high frequency (UHF) passive broadband radio frequency identification (RFID) Tag Antenna with a novel T-matching network is presented. By slightly tuned the arm lengths of the T-matching network, the impedance matching between the antenna and the chip and a broad impedance bandwidth is obtained. Thanks to the bent radiating element, the size reduction of the proposed antenna is realized. The bandwidth (S11 < −20 dB) and the corresponding 3 dB PRC bandwidth of the proposed antenna are 133 MHz (835–968 MHz) and 88 MHz (882–970 MHz) respectively, which means that both bandwidths are wide enough to cover the whole global UHF RFID frequency band. In the simulated results, a smooth and stable gain curve between 0.04 dBi to 1.86 dBi is found throughout the entire operating frequency band, and a gain of 1.38 dBi is obtained at the desired operating frequency point (915 MHz).
