초록

본 논문에서는 접지면을 변형시킨 대역 저지 특성을 갖는 CPW 급전 타원형 UWB 안테나를 제안하였다. UWB 시스템 전대역(3.1 GHz${\~}$10.6 GHz)에서 2 이하의 VSWR을 만족하는 특성을 구현하였고, IEEE 802.11a에 의한 5 GHz대역(5.15 GHz${\~}$5.825 GHz)과의 간섭을 차단하기 위해 복사 소자에 수평 슬롯을 삽입하여 안테나를 제작${\cdot}$측정하였다. 뒷면에 접지면이 없는 단일 평면의 CPW 급전 구조를 사용해 제작이 용이하였고, 초박형, 초소형화가 가능하였다. 측정 결과 UWB 전대역에서 -10 dB 이하의 양호한 반사 손실과 2.1 dB${\~}$4.75 dB의 최대 이득을 보였으며 전방향 복사 패턴을 나타내었고, 선형 위상 특성을 보였다.

This paper proposes a uni-planar elliptical element UWB antenna with band-notched characteristic and modified pound plane fed by CPW. The antenna achieves VSWR below 2 for UWB band(3.1 GHz${\~}$10.6 GHz). In addition, a band-notched characteristic is achieved by inserting a horizontal slot on the radiation element to avoid the interference with 5 GHz(5.15 GHz${\~}$5.825 GHz) band limited by IEEE 802.1la. The antenna has a thin profile, compact size, and ease of manufacture by adopting a CPW feed structure without any additional background plane. Measured data show that the proposed antenna has good return loss below -10 dB, about 2.1 dB${\~}$4.75 dB maximum gain over the bandwidth, omni-directional radiation patterns, linear phase response.
