A Broadband UHF Near-Field RFID Antenna

摘要：

　　A broadband segmented loop antenna is presented for ultra high frequency(UHF)near-field radio frequency identifica-tion(RFID)applications.Using a segmented line,the current dis-tribution along the loop is kept in phase even though the perimeter of the loop is more than two operating wavelengths so that the pro-posed antenna generates strong and even magnetic field distribu-tion in the near-field zone of the antenna.The antenna prototype,printed onto a piece of FR4 substrate,with an overall size of 175 x 180×0.5 mm3,achieves a large interrogation zone of 154 x 154 mm2 with good impedance matching and uniform magnetic field distribution over the entire UHF RFID band of 840-960 MHz.
