Abstract

In this paper, the broadband antenna for the combined base station of Cellular/PCS/IMT-2000/Wibro and S-DMB services is designed and the proposed antenna allows having sufficient coverage for each service band. In order to get the broadband impedance matching, the tapered sections are applied on the both terminus of hi-conical respectively. The design parameter is calculated and simulated by using FDTD method. As a result, the measured bandwidth of the proposed antenna is $0.79GHz{\sim}2.93GHz$ and the gain is distributed from 5.5 dBi up to 8.19 dBi.

본 논문에서는 Cellular/PCS/IMT-2000/Wibro 및 S-DMB의 서비스 대역을 모두 만족하는 통합 기지국용 광대역 안테나를 설계하였다. 바이코니컬 종단 부분에 테이퍼 구조를 적용하여 광대역 임피던스 정합을 구현하였으며, 시간영역 유한차분법(FDTD)을 통해 설계 및 시뮬레이션을 수행하였다. 측정 결과, 제작된 안테나는 대역폭 $0.79GHz{\sim}2.93GHz$에서 5.50 dBi 이상 최대 8.19 dBi의 이득 특성을 갖는다.
