초록

본 논문에서는 NEC 코드와 Pareto 유전자 알고리즘 최적화 기법을 이용하여 초소형 유도결합 안테나를 설계하였다. 최적화된 유도결합 안테나 중 몇 가지 표본을 제작하고 성능을 측정하였다. 일반적으로 안테나의 크기가 작아질수록 입력 저항, 대역폭 및 효율이 감소하는데 비하여 제안된 방법으로 설계된 유도결합 안테나는 다른 부가적인 정합회로 없이 우수한 성능을 보인다. 간단한 회로 모델을 도입하여 제안된 유도결합 안테나의 동작원리를 설명하였고, Duroid 기판 위에 평면 구조로 제작하여 RFID 태그 안테나로써 성능을 입증하였다.

In this paper, we explore the inductively coupled concept and propose a class of electrically small planar antennas. The antennas are optimized using NEC in conjunction with a Pareto GA. These antennas show good efficiency and bandwidth performance without any additional matching network. Several optimized designs are fabricated and measured. We explain the operating principle of these antennas using a simple lumped element circuit model. The proposed antennas are translated as printed lines on Duroid for RFID tag antennas.
