Abstract: In current article, Mushroom shaped Metamaterial substrate is proposed. Its unique electromagnetic characteristics such as Artificial magnetic conductor (AMC), High surface impedance (HIS) and Forbidden band gap (FBG) are determined using 3D-Electromagnetic simulation software. The architecture of proposed design contains a square patch etched on top face of dual layered FR4 epoxy substrate backed conductor, both conductors (top square patch and back conductor) are shorted by vertical conducting stub centrally through substrate. To understand the effect of AMC, HIS and FBG properties, proposed metamaterial substrate is applied as ground to edge feed microstrip patch antenna. Due to AMC, HIS and FBG properties, edge feed patch antenna radiation characteristics are enhanced when compared with conventional patch antenna design. Obtained results of return loss, radiation pattern are presented.
