본 논문에서는 다중대역 렉테나가 장착된 RF 에너지 수집 시스템의 성능 확인에 사용되는 광대역 이중리지 혼 안테나를 다중모드 회로망 분석을 이용하여 효율적으로 설계하는 방법을 제안하고 있다. 다중모드 회로망 분석을 이용하여 천이장치와 혼에 대한 각각의 고차모드 산란 파라미터를 얻어 설계에 적용하였다. 그 결과 기존 방법에 비해 계산시간이 많이 단축되었으며 안테나의 정재파비를 계산한 결과 전자기장 해석을 적용한 것과 거의 유사하였으며, 측정치와 높은 일치도를 보였다. 설계된 광대역 혼 안테나는 660∼6360 MHz 대역폭과 6∼13.7 dBi의 최대방사 이득을 가진다.
