Abstract

In this paper, a novel compact and frequency band-notch antenna for Ultra-Wideband(UWB) applications is proposed. The designed antenna not only shows good impedance bandwidth for ultra-wideband but has band notch characteristic for the frequency band of $5.15\~5.825\;GHz$ limited by IEEE 802.1la and HIPERLAN/2. To achieve both properties of wide band and band notch, the techniques of a concaved ground plane and inserted U-shaped thin slot into planar radiator are used respectively. A manufactured antenna satisfied VSWR<2 for the frequency band of $2.95\~11.7\GHz$ except the limited band of $4.92\~5.866\;GHz$.

본 논문에서는 Ultra-Wideband(UWB)통신을 위한 새로운 소형 주파수 대역 저지 안테나를 설계 및 제작한다. 설계된 안테나는 초광대역 특성을 만족하면서, IEEE 802.11a와 HIPERLAN/2에 의해 사용이 제한된 $5.15\~5.825\;GHz$에서 주파수 대역 저지 특성을 갖는다. 안테나의 광대역 특성을 얻기 위해서 요철 모양의 접지면을 구현하였고, 또한 제한된 주파수 대역에서 저지 특성을 갖기 위해 U모양의 얇은 슬랏을 사각형 복사 패치 위에 구현 하였다. 제작된 안테나는 저지 대역인 $4.92\~5.866\;GHz$을 제외하고 $2.95\~11.7\;GHz$ 대역에서 정재파비 2 이하를 만족하는 광대역 특성을 나타낸다.
