Title: 전자감응식 상품도난 방지용 원나선형 알에프 태그
Filed: 1999-03-23
Abstract: 본 고안은 상점이나 유통센터에서 상품도난을 방지하기 위해 상품에 사용되는 전자감응식 상품도난 방지용 시스템의 원 나선형 RF(Radio Frequency) 태그를 제공하는 데 목적이 있다. 
     이를 위하여 본 발명은, 전자감응식 상품도난 방지용 시스템에 사용되는 RF  태그의 새로운 구조를 제안하고 등가회로화하였다. RF 태그는 인덕터와 커패시터로 구성된 LC직렬공진 회로이며 공진 주파수는 8.2MHz이다. RF 태그의 재질은 비유전율이 2.3∼3.0인 폴리에틸렌(polyethylene), 폴리메릭(polymeric) 필름 등의 유전체와 알루미늄, 구리, 니켈, 은 등의 도체를 사용한다. 본 발명에서는 생산방식을  식각방식과 인쇄방식으로 두 가지가 가능하게  하였다. 도체를 원 나선형 구조로 함으로써 기존의 RF 태그에 사용되는 사각 나선형 인덕터의 Q(quality factor)값 보다 10% 향상되어, 결과적으로 전자감응식 상품도난 방지용 시스템의 RF 태그 감지능력이 향상되었다. 도체부분을 한 면에 동시에 제작하기 때문에 해석이 간단하고 도체와 유전체의 재질이 바뀌어도 조건에 따라 설계하기가 용이해 소형 RF 태그의 제작이 가능하다. 또한 단일 인덕터와 커패시터를 사용하여 소거기능을 강화하였으며 여러 가지 커플링에 대한 고려사항을 줄일 수 있으므로 설계과정을 단순화할 수 있고 제작 후 오차도 줄어들게 된다.
