A New Design Improvement of Microstrip U-Shape Antenna for Bandwidth Enhancement Using EBG Structure Deformation

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 U-shape patch antenna with suitable geometry is taken to provide good response of bandwidth about 30 % at centre frequency 2.025 GHz. Using FR-4 glass epoxy material, on insertion of EBG structure, creating deformities at ground plane side, the band width of the antenna is improved tremendously about 49.36 % at centre frequency 2.35 GHz. The new design of antenna is found suitable for various wireless communications for S-band. The design approach & Simulation results are shown with the help of MOM based full wave simulator IE3D.
