초록

본 논문에서는 LTE와 WiMAX 시스템에 적용 가능한 마이크로스트립 패치 안테나를 설계하였다. 제안된 모노폴 안테나의 기판은 FR-4이고 크기는 $70.88mm{\times}54.88mm$이다. 제안된 안테나는 평면형 모노폴 설계를 기본구조로 구성함으로서 LTE와 WiMAX 대역을 포함하는 이중대역 특성을 갖도록 설계하였다. 최적화된 파라메타를 얻기 위해 상용 툴(CST's Microwave Studio Program)을 사용하여 시뮬레이션 하였으며 안테나 성능에 민감하게 작용하는 파라메타를 찾아내서 최적화된 수치를 얻었다. 얻어진 최적화된 수치를 사용하여 제안된 안테나를 설계하였다. 따라서 제안된 안테나는 LTE와 WiMAX 대역을 동시에 만족하였다. 그리고 LTE와 WiMAX 대역에서 좋은 이득과 방사패턴의 특성을 얻었다.

In this letter, we designed monopole microstrip antenna for WLAN / WiMAX system. The monopole antenna is designed by FR-4 substrate with size is $30mm{\times}40mm$. The proposed antenna is based on a planar monopole design which cover WLAN and WiMAX frequency bands. To obtainthe optimized parameters, we used the simulator, CST's Microwave Studio Program and found the parameters that greatly effect antenna characteristics. Using the obtained parameters, the antenna is designed. Thus the proposed antenna satisfied the -10 dB impedance bandwidth requirement while simultaneously covering the WLAN and WiMAX bands. And characteristics of gain and radiation patterns are obtained for WLAN/WiMAX frequency bands.
