Abstract

In this paper, we proposed and fabricated the single-feed dual-band circular patch antenna for S-DMB(Satellite-Digital Multimedia Broadcasting) and ITS(Intelligent Transport Systems) services. The manufactured dual-band antenna showed that the measured -10 dB bandwidth and the minimum return loss was 90 MHz and -35 dB for S-DMB, 180 MHz and -18 dB for ITS, respectively. It is noticed that the measured and the simulated results are agreed well. And the antenna gain of S-DMB and ITS has 2.3 dBi and 2.7 dBi, respectively.

본 논문에서는 단일 급전을 이용하여 위성 DMB(Digital Multimedia Broadcasting)와 ITS(Intelligent Transport Systems) 서비스를 수신할 수 있는 이중 대역 원형 패치 안테나의 구조를 제안하고, 실제 제작을 통하여 성능을 확인하였다. 제작한 이중 대역 안테나는 위성 DMB 대역과 ITS 대역에서 각각 90 MHz와 180 MHz의 -10 dB 대역폭을 갖고, 최소 반사 손실은 약 -35 dB와 -18 dB로 측정되었는데, 이는 시뮬레이션 결과와 잘 일치하였다. 그리고, 위성 DMB와 ITS 대역의 안테나 이득은 각각 2.3 dBi와 2.7 dBi를 얻었다.
