This paper proposes a printed tag antenna for the universal ultra-high frequency (UHF) radio frequency identification (RFID) band (860-960 MHz) using the R2R process. To widen impedance bandwidth, a π-shaped matching network is suggested. The overall dimension of the proposed tag antenna is 83.4 mm 30.2 mm and it has a gain of over 1 dBi for the entire UHF RFID band. The performances of the proposed tag antenna, printed with conductivity silver ink using an R2R process, are compared with those of a copper antenna.
