The aim of this paper is to design and simulation of Coplanar Waveguide (CPW) ring shaped antenna for multiple wireless applications. The antenna is designed by FR-4 substrate with dielectric constant of 4.4 and the substrate thickness of 1.6mm. The antenna occupies a compact size (L x W) 36mm x 36mm. The radiating patch is etched/cut with C-shaped slot to generate multiple frequencies for various wireless applications. Copper materiel used as a conducting material for radiating patch and ground. An introduced antenna design covers five frequency bands for GPS (1.63GHZ), WLAN (2.4 GHz), WIMAX (3.380GHZ), C-band (4.0450 GHz), and WIFI (5.0250GHZ) applications. The antenna is designed and all results are simulated by using High Frequency Structure Simulated (HFSS) simulation software. Return loss, VSWR and field pattern of the proposed antenna is plotted and all frequency bands are found to have return losses (s11) less than -10 dB and VSWR less than 2.
