A COMPACT DUAL-BAND PRINTED MONOPOLE ANTENNA FOR WIMAX/WLAN APPLICATIONS

Abstract

A compact printed dual-band antenna for WiMAX/WLAN applications is proposed in this paper. The dual-band monopole antenna consists of a triangular patch and two folding arms shorted to the ground plane. The proposed antenna features a low proflle and compact dimension. To avoid via process in the fabrication, the triangular patch and two folding arms are separately constructed on the two sides of a FR4 substrate. By employing this structure, flve difierent resonances can be yielded. The triangular patch provides two resonant modes (4.62GHz and 7.05GHz). The two folding arms produces three resonances at 2.43GHz, 3.43GHz, and 6.59GHz. A prototype of the dual-band antenna is experimentally fabricated and tested. The measured results shows good impedance bandwidth and radiation pattern.
