Abstract:
This article presents the design of a small‐ and low‐profile radio frequency identification tag antenna in the UHF band that can be stuck to metallic objects. The designed tag antenna, which uses a ceramic material as an antenna substrate, consists of a radiating patch and microstrip lines for a proximity‐coupled feeding structure. Impedance matching can be simply obtained between the antenna and tag chip without any matching network using the antenna structure. The return‐loss bandwidth for S 11 〈 10 dB and radiation efficiency are about 9.5 MHz and 40% at 911 MHz, respectively. The read range is approximately from 3 to 3.5 m when the tag antenna is mounted on a metallic surface. © 2008 Wiley Periodicals, Inc.
