Abstract

This paper is concentrated on analyzing the performance of passive ultra-high frequency (UHF) radio frequency identification (RFID) tags in which different impedance matching approaches have been used. Analysis and discussion is based on modeling results and measurements of the tags in active state. In the analysis, we will concentrate on comparing the performance of a dipole-type tag antenna with T-match, two-wire and three-wire folded dipole tag antennas and a microstrip patch-type tag antenna.
