초록

본 논문에서는 다중 선로를 로딩시킨 새로운 구조의 글래스 안테나를 설계하였다. 제안된 안테나는 광대역 주파수 특성을 얻기 위하여 중심 선로에 다중 선로를 로딩하였으며, 수직 편파 복사 이득을 개선하기 위하여 이중 중심 선로 구조를 채택하였다. 세부적인 설계 변수는 Pareto 유전자 알고리즘을 이용하여 최적화하였으며, 이러한 설계 변수를 바탕으로 글래스 안테나를 실제 차량 유리에 인쇄한 후 측정하였다. 측정 결과, T-DMB 중심 주파수를 기준으로 49 %의 반전력 대역폭과 -3 dBi 이상의 전면 방향(bore- sight direction) 수직 편파 복사 이득, azimuth 방향에서 평균 -10 dBi 이상의 수직 편파 복사 이득을 보였다.

In this paper we propose an on-glass antenna which consists of conducting dual center striplines and multi-loaded striplines. Multi-loaded striplines and dual center lines were employed for achieving a broad matching bandwidth and improving a vertical radiation gain, respectively. The detail design parameters were determined using the Pareto genetic algorithm with an full wave EM simulator. The optimized design was built and installed on a commercial vehicle, and the antenna performances such as the return loss and the radiation gain were measured in a semi-anechoic chamber. The measurement results showed the matching bandwidth($S_{11}$<-3 dB) of about 49 % in the T-DMB frequency band, the vertical gain of about -3 dBi along the bore-sight direction, and the average gain of about -10 dBi along the azimuth direction.
