Abstract

This paper presents a CPW-fed antenna for wideband application. This Antenna satisfies the licensed frequency band of WLAN (5.15-5.85)GHz and X-Band(8-12)GHz application. A resonant frequency for WLAN at 5.57GHz and 11.27GHz for h=1mm having return loss lower than -10dB. This antenna is designed on a substrate with dielectric constant ε_r=4.4. With a size 15.2mm×15.6mm×1mm the antenna operates for wideband application. The effects of shape, length, size, and location of feeding point, substrate and their thickness have been evaluated. And obtained 2D radiation patterns with elevation, VSWR, Return loss, gain and antenna efficiency. The simulation results of this antenna are analyzed by using Method of Moment (MoM) from IE3D software.
