Abstract :
In this paper, a micro strip patch antenna mounted over a high impedance electromagnetic band gap (EBG) substrate is proposed. The proposed antenna design is simulated on electromagnetic (EM) simulation software using FR-4 substrate with dielectric constant of 4.54 and thickness of 1.60mm. The proposed antenna has a compact structure with a total size of 60x60mm2. The bandwidth of micro strip patch antenna is enhanced by adjusting the parameters such as the gaps between adjacent patches in two orthogonal directions- the X-direction and the Y-direction respectively and the radii of the related vias. In addition, the EBG cells are placed in E-plane for surface wave reduction. A novel design of this micro strip patch antenna using mushroom-like EBG structure is integrated with these efficient methods which exhibits distinctly wider bandwidth than the conventional one. The simulated results show the good agreement with the proposed scheme.
