Abstract
A small UHF RFID tag antenna for a key-chain installed inside of a metallic key-management cabinet has been designed. The tag antenna has been designed as small size as $66\;mm{\times}6\;mm$ with consideration of coupling among the tag antennas and metallic parts of key-chain and cabinet. The tag antenna is fabricated with a meander line dipole using T-matching method with FR-4 substrate. One tag antenna has been designed with consideration of coupling of adjacent tag antennas, and the other has been designed for the location close to the metallic part in the cabinet. The characteristics of tag antennas and reading distance have been analyzed based on the different numbers of adjacent tag antennas. As a results, the 360 tag antennas installed in the cabinet have been successfully recognized.
