Abstract

In this study, a novel dual band planar monopole antenna for wireless local area network (WLAN)/ Worldwide Interoperability of Microwave Access (WiMAX) application was designed, fabricated, and measured. The proposed antenna consists of two hook shaped strips, an asymmetric ground plane, and a rectangular slit in the ground plane. Acceptable agreements between the measured and simulated results are achieved. Numerical and experimental results demonstrate that the proposed antenna satisfies the 10 dB impedance bandwidth requirement while covering the WLAN and WiMAX bands simultaneously. This paper also presents and discusses the 2D radiation patterns and 3D gains according to the results of the experiment that was conducted.

본 논문은 WLAN/WiMAX 시스템에 적용 가능한 이중대역 평면형 모노폴 안테나를 설계, 제작 및 측정하였다. 제안된 안테나는 2개의 훅크 모양의 선로, 비대칭 접지면 그리고 접지면에 사각 슬릿을 갖도록 설계하였다. 측정과 시뮬레이션 결과사이의 데이터가 잘 일치하고 있는 데이터를 얻었으며 -10dB 임피던스 대역폭을 기준으로 WLAN과 WiMAX 대역을 동시에 만족하고 있음을 확인하였다. 또한 2D 그리고 3D 방사패턴과 이득에 측정결과가 제시되고 논의되었다.
