Abstract: The paper presents the improvement in the performance of eight element microstrip antenna array. The overall bandwidth of the proposed microstrip antenna array is equal to 262.7 % as compared to 4.98 % of the conventional antenna array. The proposed microstrip antenna array is producing good reduction in mutual coupling values at the resonant frequency of 5.53 GHz. The proposed microstrip antenna array is producing a healthy size reduction of 60.03 %. FR-4 glass epoxy substrate is used as dielectric substrate which has a dielectric constant of 4.2 and loss tangent of 0.0245. The microstrip antenna arrays are designed using Mentor Graphics IE3D simulation software.
Keywords: Electromagnetic band gap structure, microstrip antenna array, mutual coupling, return loss, silver coating.
