Compact novel CPW- fed antenna for WLAN application

Abstract

This paper presents a CPW-fed antenna with a triangle placed on a rectangular patch with two semi circles placed on either sides for WLAN application. This Antenna satisfies the licensed frequency band (5.15 to 5.95 GHz) having return loss lower than -10 dB. The antenna is designed on a substrate with dielectric constant ε _r =4.4. The size of the antenna is 15.6mm×15.2mm×1mm. 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, antenna efficiency. The simulation results of this antenna are analyzed by using Method of Moment (MoM) from IE3D software.
