Abstract
A miniaturized UHF band tag antenna which is composed of a compact folded dipole is presented.The tag antenna has a T-match loop that brings about a good impedance match.Input impedance of the proposed tag antenna is 7.40+j112.98 Ω,which is conjugate-matched up a Alien Higgs2 IC chip with impedance of 7.4-j113 Ω at 915MHz.Its total size is 20mm×60mm,which is reduce about 25% of a conventional folded dipole tag antenna.The operating bandwidth(return loss less than-3 dB,884 MHz ~958 MHz)covers 74% of the entire UHF RFID band.It has a high gain of 0.94dBi.The proposed antenna keeps good radiation performance and has advantages of low cost and small size.关键词
