A COMPACT DUAL-BAND PATCH ANTENNA FOR WLAN APPLICATIONS

Abstract

A compact dual-band patch antenna is proposed and measured in this paper. The proposed antenna employs a U-shaped slot and two mitered corners to achieve two operating frequency bands, 2:30 » 2:50GHz and 4:50 » 6:36GHz, which meet the speciflcations of IEEE 802.11b/g/a standard for WLAN applications. Full wave analysis is performed to simulate the characteristics of the proposed antenna using CST microwave studio. Moreover, a fabricated prototype which has compact dimensions of 20:0mm£25mm£1mm exhibits agreement between measured and simulated parameters and radiation patterns.
