Abstract

A circularly polarized (CP) UHF RFID tag antenna is proposed in this paper. This antenna is realized by a meandering cross dipole. The meandering structure of the dipole could adjust amplitudes and phases from the two orthogonal arms of the cross dipole such that a CP frequency would be generated by the mutually-orthogonal mode. Therefore, we can achieve CP operation from the tag. The maximum transmitted power can be obtained when the input impedance of the tag is conjugate-match with the impedance of the RFID chip. A special matching structure is employed in this design to control the input impedance of the tag. This tag antenna is designed to cover whole UHF band (840-960 MHz), and its 3-dB axial-ratio (AR) bandwidth is 43 MHz (905-948 MHz). © 2013 IEEE.
