A Novel UHF RFID Tag Antenna for Cigarette Carton

A novel UHF RFID tag antenna that can be seamlessly integrated into wrapping paper of metallic objects is reported. When designed for printing on cigarette carton with aluminum foil contained, both numerical simulation and measurement indicate that the proposed antenna has input impedance of (20 + j149) at resonant frequency of 915MHz, which provides satisfactory conjugate match to the Alien Higgs-2 RFID ASIC. The UHF RFID tag with designed antenna on cigarette carton demonstrates -10dB return loss bandwidth of 31MHz at the 915MHz UHF RFID band, and a read range of approximately 0.63m.
