Abstract

In this paper, a folded label type RFID tag antenna is designed and produecd for metellic environment over UHF band. Since performance of regular label type RFID tag is seriously degraded for the metallic environment, a folded label tag is proposed to improve the performance. The proposed tag is operating at 910MHz by using inductive T Matching Feed and simulated in HFSS by Ansoft. The actual size is $65{\times}23{\times}3(mm)$ with the impedance of $52-j158{\Omega}$. The maximum distance of identification for the proposed tag is measured as 5.5 meters.

본 논문에서는 일반라벨 형태의 태그를 접어서 금속환경에 사용 가능한 RFID(Radio Frequency Identification) 태그 안테나를 설계 및 제작을 하였다. 일반 라벨 태그의 경우, 금속 환경에서 인식이 열화되는 단점을 보완하여 접힌 형태의 태그 안테나를 제안한다. Ansoft사(社)의 HFSS를 사용하여 칩 임피던스는 $52-j158{\Omega}$에 따라 910MHz에서 동작하도록 설계되었다. 태그의 크기는 $65{\times}23{\times}3(mm)$이며 실제 제작 후 테스트 결과 5.5M까지 인식되었다.
