A compact wideband monopole antenna designed for wireless applications

A Compact Wideband Monopole Antenna, designed for wireless applications has been investigated in this paper. The antenna consists of a Radiating Patch along with a Defected Ground Plane. The proposed antenna has been compared with a similar Radiating Patch without any Defected Ground Structure (DGS) and the results have been discussed with comparison plots. The proposed antenna covers a frequency range of 2.4 GHz to 6.0 GHz with an impedance bandwidth about 85.71 %. The proposed antenna finds its application in IEEE 502.11a WLAN band (5.15-5.85 GHz), IEEE 502.11b WLAN band (2.4-2.5 GHz) and IEEE 802.16 WiMAX band (3.2-3.5 GHz).
