Abstract
Novel electrically small low‐profile dual‐loop antenna over artificial‐like surface, formed by four‐element sub‐wavelength patch array printed on grounded dielectric slab used for shielding in UHF RFID applications, has been developed. The badge‐sized antenna exhibits the gain of about 1 dBi and antenna efficiency amounting to approximately 30–40% whether it is placed in free space or enclosed to dielectric/metallic objects. © 2009 Wiley Periodicals, Inc.
