One of the ways to achieve high gain in microstrip antennas is by using electromagnetic band-gap (EBG) structures. Incorporating EBG in the design supresses surface waves in the antenna ground plane and also helps in obtaining a uniform field distribution. The main objective of this paper is to obtain a high gain antenna suitable for WiMAX application by simply placing multiple EBG structures on the same plane of patch antenna. A simple microstrip patch antenna with and without EBG structures is designed and simulated using AnsoftHFSSTMsoftware with FR4 substrate having a dielectric constant of 4.4, loss tangent of 0.02 and thickness of 1.57mm at a resonating frequency of 5.6 GHz. The proposed EBG antenna increased the gain by approximately two times when compared with a simple micro-strip patch antenna.
