This paper proposes an antenna of the fork type structure that operates in the UWB (Ultra Wide Band) frequency band (3.1 ~ 10.6 GHz). The proposed antenna is attached a circular patch in order to obtain the UWB band characteristics to the fork-type patch antenna. The ground plane is implemented in a arc-shape configuration. The effect of various parameters of the modified fork type radiating patch and partial arc ground plane for UWB operation is investigated. The proposed antenna is made of $34.0{\times}50.0{\times}1.0mm^3$ and is fabricated on the permittivity 4.4 FR-4 substrate. The experiment results shown that the proposed antenna obtained the -10 dB impedance bandwidth 8200 MHz (2.7 ~ 10.9 GHz) covering the UWB bands. This result satisfied the characteristics of ultra-wideband and the proposed antenna will be applicable to an ultra wideband system.

본 논문에서는 UWB (Ultra Wide Band) 주파수 대역 (3.1 ~ 10.6 GHz)에서 동작하는 안테나를 제안한다. 제안된 안테나는 UWB 대역 특성을 얻기 위하여 기존 포크형 구조에 원형 패치를 결합하고, 접지면을 원호 구조로 구현하였다. 구현된 안테나는 유전율 4.4인 FR-4 기판 위에 설계되었고 전체 크기는 $34mm(W){\times}50mm(L){\times}1mm(t)$ 이다. 최적화된 수치를 사용하여 제안된 안테나를 제작하였으며 특성을 실험한 결과 UWB 대역에서 약 -10 dB 이하의 반사 손실, 전류분포, 이득, 방사패턴의 특성을 측정하였다. 이와 같은 실험결과로 광대역 통신시스템에 활용이 가능할 것으로 판단된다.
