Abstract :
In this paper, a dual-band circularly polarized antenna is designed for the UHF band (860 MHz ~ 960 MHz) and ISM band (2.4 GHz ~ 2.48 GHz) RFID reader applications and novel microstrip patch RFID tag antennas for the UHF RFID band (908 MHz -914 MHz) in Korea are proposed. They have less sensitive characteristic against the size of metallic object, wide impedance bandwidth and a long reading distance.
