Abstract: In this research article, a microstrip patch antenna for Wireless Applications is presented. Stage by stage, the antenna is modified to achieve the desired wideband characteristics. The final proposed antenna is a combination of U and Quad L shaped slots with L shaped DGS and U shaped dual parasitic elements. Parameters S11, bandwidth and gain of the antenna versions during each stage are noted and steps are taken to improve these parameters. The end result is a wideband microstrip patch antenna working in the frequency range of 4.75 GHz to 6.15 GHz with a bandwidth of 1.40 GHz. The peak gain observed is about 7.24 dB at 5.64 GHz frequency. Simulations are carried out using HFSS software. The obtained results show that the proposed antenna can be extensively for WiFi (4.9 GHz to 5.9 GHz) and WiMax (5.3 GHz to 5.8 GHz) Applications.
