A compact Coplanar Waveguide (CPW) fed Hexagon shaped slot antenna is proposed for Wi-Max application. The proposed antenna has a size of 20mm x 16.5mm x1.6mm and it is designed on Rogers RT/Duroid substrate with a dielectric constant of 2.2. The proposed antenna resonates at 7.5 GHz and has a bandwidth of 1.2 GHz, Return Loss (S11) of -51.5dB, Gain 3.7 dBi, VSWR of 1 at 7.5 GHz. The near field and far field radiation patterns are bi-directional and Omni-directional in E and H planes. The__ampersandsignnbsp;proposed antenna is used for Wi-Max applications and the antenna has an impedance bandwidth of 86%. The proposed antenna is simulated using Ansoft High Frequency Structure Simulator (HFSS) version 13 which is based on Finite Element Method and the antenna parameters are analyzed.
