Abstract

An Asymmetric Coplanar Strip (ACS) fed uniplanar antenna for wide band applications is presented. The resulting antenna offers a 2:1 VSWR bandwidth greater than 100% from 1.65 GHz to 5.06 GHz covering the DCS/PCS/IEEE 802.11a/WiMAX bands. The antenna has an overall dimension of 44 mm X 35 mm when printed on a substrate of dielectric constant 4.4 and height 1.6 mm. The wide band width is obtained by combining three individual resonances excited by various current paths. The antenna exhibits good radiation characteristics and moderate gain in the entire operating band.
