Abstract

In this paper, the slot-coupled microstrip antenna structure with reflector is used for broadband. The reflector of this structure is designed to reduce the radiation emitted from the slot and minimize the influence of external electromagnetic environment while reducing the overall antenna height. Experimental results show that the antenna is very well matched with VSWR below 1.4 at 1.942.17GHz, and the maximum gain of the antenna in this band was measured 9.21dBi. The measured results shows that it can be used in the wireless communication field or IoT field of other frequency band in the future.

본 논문에서는 마이크로스트립 안테나가 광대역특성을 갖기 위해 반사판을 갖는 슬롯 결합 마이크로스트립 안테나 구조를 사용하였다. 본 구조에서 반사판은 슬롯으로부터 나오는 방사를 줄이고 외부 전자파 환경 영향을 최소화 하면서 동시에 전체 안테나 높이를 줄이는 역할을 할 수 있도록 설계하였다. 실험 결과 1.94~2.17GHz에서 VSWR이 1.4이하로 매우 잘 정합된 안테나를 제작하였으며, 안테나의 이득도 최고 9.21dBi를 얻어 높은 이득을 얻을 수 있었다. 향후, 다른 주파수 대역의 무선통신 분야나 사물통신(IoT) 분야에도 사용할 수 있을 것으로 사료된다.
