Abstract

In this paper, a microstrip-fed multiband monopole antenna for GPS(Global positioning system)/WiMAX(:Worldwide interoperability for microwave access)/WLAN(Wireless Local Area Networks) for applications was designed, fabricated and measured. The proposed antenna is based on a microstrip-fed structure, and composed of two rectangular double rings and L strips pair and then designed in order to get triple band characteristics. To obtain the optimized parameters, we used the simulator, Ansoft's High Frequency Structure Simulator(HFSS). The proposed antenna is made of $27.0{\times}54.0{\times}1.0mm3$ and is fabricated on the permittivity 4.4 FR-4 substrate. The experiment results shown that the proposed antenna obtained the -10 dB impedance bandwidth 300 MHz (1.325~1.625 GHz), 400 MHz (2.275~2.675 GHz), and 600 MHz (3.15~3.75 GHz) covering the GPS/WiMAX/WLAN bands. Also, the proposed antenna measured gain and radiation patterns characteristics for required operating bands.

본 논문에서는 GPS/WiMAX/WLAN 시스템에 적용 가능한 다중밴드 대역을 갖는 모노폴 안테나를 설계, 제작 및 측정 하였다. 제안된 안테나는 마이크로스트립 급전을 바탕으로 두 개의 사각 링과 한 쌍의 L 선로로 구성되어 삼중 대역의 특성을 갖도록 설계하였다. 최적화된 수치를 얻기 위해 상용 툴인 HFSS을 사용하여 시뮬레이션을 수행하였다. 제안된 안테나는 $27.0{\times}54.0{\times}1.0mm3$의 크기로 유전율 4.4인 RF 4 기판 위에 제작되었다. 제작 결과, 제안된 안테나는 -10dB 임피던스 대역폭을 기준으로 300 MHz(1.325~1.625 GHz), 400 MHz (2.275~2.675 GHz), 그리고 600 MHz (3.15~3.75 GHz)의 대역폭을 얻었다. 또한 제안된 안테나는 요구되는 3개 대역에서 측정된 이득과 방사패턴의 특성을 얻었다.
