A CPW-fed antenna for dual band WiMAX/WLAN applications

This paper presents a Novel antenna for dual band application. This Antenna is designed to satisfy two licensed frequency bands (2.7 to 2.9 GHz); (5.15 to 5.85 GHz). These bands are suitable for WiMAX and WLAN applications. This antenna is designed on FR4 substrate with dielectric constant εr=4.4. With size 26.5mm×32mm×1.6mm. The effects of extrusion depth and number of rectangular shapes side patches and triangular shape radiating patch, length, and size have been evaluated. This paper includes 2d radiation patterns with elevation and azimuthal, VSWR, return loss and gain. The simulation results of this Novel antenna are analyzed by using Method of Moment (MoM) from IE3D software. To save cost and space, an antenna capable of operating in at least two Frequency bands are required.
