초록

본 논문에서는 U자형 슬롯을 사용하여 802.11a(5.15 ~ 5.825 GHz) 대역을 제거한 CPW(Coplanar Waveguide) 구조를 갖는 UWB(Ultra Wide Band) 안테나를 제안한다. 제안된 안테나는 UWB 통신에 적합한 초광대역 특성(3.1~10.6 GHz)을 만족하면서, 5 GHz WLAN 대역(5.15 ~ 5.825 GHz)에서 주파수 대역 저지 특성을 갖는다. 안테나는 유전율 4.4인 FR-4 기판 위에 설계되었고 전체 크기는 $30mm(W){\times}20mm(L){\times}1mm(t)$ 이다. 제작된 안테나는 저지 대역인 5.15 ~ 5.825 GHz를 제외하고, 3.1 ~ 10.6 GHz 대역에서 $VSWR{\leq}2$를 만족한다. 그리고 동작대역에서 측정된 이득과 방사패턴의 특성을 나타내었다.
