Abstract :
An RFID tag consists of tag antenna and a microchip. The terminal impedance of the chip varies in two states. It also affects the RCS and read range of the tag antenna. This paper presents a circularly polarized compact UHF RFID tag antenna with impedance of commercially available chip. The tag antennapsilas RCS patterns and read range are also analyzed in different planes.
