CPW- fed antenna with two rectangle slots for wideband application

This paper presents a CPW-fed antenna for wideband application. This Antenna satisfies the licensed frequency band of wireless communication and covers WLAN (5.15–5.85)GHz application for h= 0.5mm having return loss lower than −10 dB. This antenna is designed on a substrate with dielectric constant εr=4.4. With a size 27.5mm×28mm×0.5mm 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.
