Abstract

A Rectangular Microstrip Patch Antenna with a size of 94 X 78 X 0.787 mm3 is put forward for IEEE 802.11 b/g/n applications where the performance of various antenna parameters is keenly improved by using Metamaterials. The Conventional Antenna is designed with the presence of Rogers RT Duroid 5870 Substrate with epsilon value of 2.33. In order to upgrade performance, EBG Structures in the form of Square Split Ring Resonator which is modified as previously been available is directly etched on the Ground Plane of Conventional Antenna. On this incorporation, we found that the Conventional Antenna which previously suffers from Narrow Bandwidth, Low Efficiency and Low Gain is sparsely enhanced where the Bandwidth was improved to +23.10%, Efficiency and Gain improved to a 17.15% and +51.35% respectively. In earlier works, the EBG Structures was attached to the radiating patch making it ineffective for modern day’s applications but here the incorporation is done without disturbing the radiating patch and the EBG Structures are modeled in such a way where it tackles mutual coupling. So keeping in view with the desires of Wi-Fi (Wireless Fidelity) Applications certain technical issues need to be addressed where the designed prototypes fulfill them out.
