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 85.74 % 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. Moreover, the radiation properties of conventional antenna array are improved with good reduction in power radiated in the undesired direction. The proposed microstrip antenna array is producing a healthy size reduction of 47.19 %. 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 software.
