Abstract :
In this paper, a compact high gain CPW-fed slot antenna for WLAN/WiMAX applications is proposed. This antenna satisfies the licensed frequency band of WiMAX (5.25~5.85 GHz) and 5 GHz WLAN band. The antenna consists of ground plane, hut shaped slot, inverted T shaped exciting stub with three symmetric Y-junctions. The inverted T shaped exciting stub with three symmetric Y-junctions has less parameter, which are convenient to optimize. This antenna is designed on a substrate with dielectric constant ϵr =4.4 and with size 16mm×16mm×1.6mm. The fundamental parameters of the antenna such as 2D radiation patterns, VSWR, return loss, gain, directivity and antenna efficiency are obtained and all meets of the acceptable standards of basic antenna. The simulation results of this antenna are analyzed by using Method of Moment (MOM) from ZELAND IE3D version 12.0 software.
