Abstract

In the electromagnetic and antenna community, the utilization of electromagnetic band-gap (EBG) structures is\nbecoming attractive. In this paper, a mushroom-like EBG structure is analysed and designed to demonstrate the mutual\ncoupling reduction and surface wave suppression. The simulations are carried out using IE3D simulation tool. All structures\nare analysed, designed and fabricated using commercially available low cost FR4 material. In this paper, microstrip patch\nantennas are analysed and designed to operate at a frequency of 2.45GHz (operate at S and L band) for different substrate\nthicknesses and permittivity. Properties like radiation pattern, gain, mutual coupling are extracted to study the performance of\nantenna system. As a result, mutual coupling reduction of 8dB is obtained.
