OPTIMIZATION IN SIZE WITH EFFECTIVE BANDWIDTH ENHANCEMENT OF MICRO STRIP PATCH ANTENNA USING PBG STRUCTURE

Abstract

Microstrip antenna has become more populer in the field of communication due to its verstality & uniqueness.The purpose of this paper is to design a low profile, conformal, small size antenna with high bandwidth along with good compromise in other factors like gain, directivity, efficiency etc. A E-shape patch antenna with suitable geometry is taken to provide good response of bandwidth about 59.09 % at centre frequency 2.28 GHz. Using FR-4 glass epoxy material, on insertion of PBG structure, creating deformities at ground plane side, the band width of the antenna is improved tremendously. The new design of antenna is found suitable for various wireless communications for 1.55-2.85 GHz band. The design approach & Simulation results are shown with the help of MOM based full wave simulator IE3D.
