摘要

A slot-coupled dipole antenna is presented for dual-hand passive radio frequency identification (RFID) tag application. A structure using a slot-coupled,feed is explored to achieve dual-band operation. The proposed antenna satisfies the -10 dB return loss characteristics front 840 to 940 MHz (11%) for ISO 18000-6 and from 2.26 to 2.56 GHz (12%) for ISO 18000-4 applications, respectively. The simulated and measured return loss results (ire in good agreement. Also reasonably good radiation characteristics are obtained for 900 MHz and 2.45 GHz RFID bonds.
