Abstract: Current paper concentrates on the design and analysis of novel stacked Electromagnetic Band Gap structures. The surface properties of both the novel designs, for instance, High surface impedance (HSI), Artificial Magnetic Conductor (AMC) and Forbidden band gap (FBG) are overseen by utilizing Finite element method (FEM) based 3D electromagnetic (EM) simulator. The acquired outcomes are contrasted with the outcomes of classical mushroom EBG structure. Proposed novel structures are named here as Progressive Stacked Electromagnetic Band Gap (PSEBG) and Stacked Electromagnetic Band Gap (SEBG). The unit cell of SEBG and PSEBG are analogue to MEBG structure, incorporates two layers over the principle plane. Top layer is a planar MEBG, middle layer contains cluster of small square MEBGs. Both proposed and reference structures are applied as ground plane to microstrip patch antenna (MPA). Radiation characteristics return loss, Front to back radiation, compact and low profile properties are studied and presented to optimize the best EBG.
Keywords: Electromagnetic (EM), Mushroom Electromagnetic Band Gap (MEBG), Artificial Magnetic Conductor (AMC), forbidden band gap (FBG).
