CPW-fed semi circle patch antenna for 2.4GHz WLAN application

This paper presents a CPW-fed semi circle patch antenna for 2.4GHz WLAN application. This Antenna satisfies the licensed frequency band (2.4 to 2.480GHz) having return loss lower than −10 dB. This antenna is designed on a substrate with dielectric constant ^εr =4.4. With a size 30mm×27mm×1.75mm the antenna operates for WLAN 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.
