Abstract

A slot‐coupled dipole antenna is presented for dual‐band 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 from 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 are in good agreement. Also reasonably good radiation characteristics are obtained for 900 MHz and 2.45 GHz RFID bands. © 2009 Wiley Periodicals, Inc.
