Investigation of a microstrip patch antenna with EBG structures using FDTD method
In this paper, a novel design of an electromagnetic band-gap (EBG) structure using finite difference time-domain (FDTD) solver has been proposed for application in microstrip antennas. This EBG structure when incorporated with microstrip patch antenna is found to increase its gain remarkably. The designed EBG structures suppress propagation of surface waves at a particular band-gap frequency and have been found to decrease reflection loss significantly. The EBG structure has been designed for a band-gap 6.5 to 8.5 GHz. This structure has been applied on a rectangular patch substrate with dielectric constant 6.6. The gain using the designed structure has been found to be 6.306 dB at 7.5 GHz.
