초록

본 논문에서는 UWB 통신 시스템에서 사용될 수 있는 CPW 급전을 이용한 새로운 육각 슬롯 구조를 가지는 UWB 안테나를 제안하였다. 제안된 안테나는 임피던스 대역폭을 넓히기 위해서 육각 패치(patch)를 가진다. 또한 IEEE 802.11a 대역과 상호 간섭 문제를 피하기 위해서 패치 위에 다각형 슬롯을 삽입하였다. 제안된 안테나는 유전율이 4.7이며, 두께가 1.6 mm인 FR-4 기판으로 제작하였으며, VSWR 특성과 그룹딜레이를 측정하였다. 제작된 안테나는 IEEE 802.11a 대역을 제외하고는 4 dBi의 이득 변화량을 나타내었다.

This paper suggests a CPW-fed UWB antenna with new hexagonal slot. To increase the impedance bandwidth of an antenna, the proposed antenna is designed with the hexagonal patch. Polygonal slot is inserted in the hexagonal patch to avoid interference with IEEE 802.11a. The proposed antenna was fabricated on FR-4 substrate with a relative dielectric constant 4.7 and thickness of 1.6 mm and measured for VSWR Characteristic and group delay. The fabricated antenna shows that the gain flatness is 4 dBi except at the band for IEEE 802.11a.
