Abstract

Band-notched ultra-wideband (UWB) antennas using frequency selective surfaces (FSSs) are presented. The proposed antennas utilized the band rejection characteristic of typical FSS unit cells. We loaded the FSS unit cells on the same plane of planar UWB antenna. These antennas are designed to reject the interference from the wireless local area network band, 5.15-5.825 GHz in the UWB band, 3.1-10.6 GHz. The measured peak gains of the proposed antennas are more than 2 dBi at both operation edge and center frequencies, and sufficient to apply for commercial purpose. The antennas are small size and planar shape for the purpose of the small mobile application, and enhanced design freedom by using various existing FSS unit cells.

본 논문은 주파수 선택 표면 (FSS)을 이용한 대역저지 ultra-wideband (UWB) 안테나를 제안한다. 제안된 안테나는 일반적인 FSS 단위 셀의 특성을 이용하여 UWB 대역 중 특정대역을 저지 할 수 있다. 안테나의 FSS 단위 셀구조는 UWB 안테나 구조체와 동일면에 설계하였으며, UWB 대역 (3.1-10.6 GHz) 중 무선 근거리 통신대역(5.15-5.825 GHz)의 간섭을 막기 위해 고안되었다. 제작된 안테나의 실제 측정된 이득은 저지 대역을 제외한 전 대역에서 2 dBi 이상이다. 제안된 안테나는 소형 모바일 장치에 적용이 가능 한 크기이며, 평판형 구조로 설계되어 다양한 FSS 단위 셀에 적용 할 수 있으며, 다양한 상용 UWB 시스템에 적용이 가능하다.
