Because of the booming demand in wireless communication system applications, micro strip patch antennas have attracted much interest due to their low profile, light weight, ease of fabrication and compatibility with printed circuits. E-shaped microstrip antenna array operating at 2.4 GHz. Design antenna is found to possess predictable high gain with different possible direction of radiation pattern. Comparative analysis has made with single, two and four elemental array. Improvement in gain from 0, 2.5 and 5dbi. Simulation is carried out using IE3D software and it is found that simulated results are in good agreement with experimental results.
