초록

본 논문은 UHF 대역 RFID 시스템용 고감도 광대역 태그 안테나의 설계에 대하여 기술한다. 제안된 태그 안테나의 크기는 $60\;mm\;{\times}\;10\;mm\;{\times}\;1\;mm$이다. 공진 주파수는 910 MHz 이고, - 10 dB이하 대역폭은 약 900 MHz이다. 측정된 반사손실과 지향성 패턴은 계산결과 잘 일치하는 것으로 확인되었다. 칩을 가진 제안한 태그 안테나의 인식거리는 6.5 m로 관측되었으며, 이 값은 상용 태그 안테나의 인식거리보다 평균 0.5 m이상 멀리 감지된 결과이다.

This paper presents the design of high sensitive/broadband tag antenna for Radio Frequency Identification (RFID) in Ultra High Frequency(UHF) band. A proposed tag antenna size is $60\;mm\;{\times}\;10\;mm\;{\times}\;1\;mm$. The resonant frequency is 910MHz and bandwidth is about 900 MHz at -10 dB below. The measured return loss and directional pattern have been confirmed a good agreement with the calculation results. The read range of proposed tag antenna with chip is observed about 6.5 m and proposed tag antenna has been observed an average 0.5 m for more than read range of the commercial tag antenna.
