Design and Analysis of Rectangular Microstrip Array Based Electromagnetic Band Gap (EBG) Structure for Microwave Applications
Patch antennas decreases the antenna efficiency due to excitation of surface waves on the substrate. In this work, a mushroom like Electromagnetic Bandgap Structures (EBGs) is designed and analyzed using Comsol Multiphysics. Five element microstrip patch antenna array on a uniform substrate has been employed that forms strong mutual coupling due to the pronounced surface waves. The excitation frequency domain for the proposed designed used is in-between 2.1GHz to 2.35GHz. The minimum wavelength selected is 0.127m. The results showed successful design implementation for a resonant frequency 2.14GHz.
