In this communication, the return loss (RL) and directivity of a high-directivity electromagnetic bandgap (EBG) antenna operating in a broad frequency band are explored. This EBG antenna uses a frequency selective surface (FSS) as the superstrate layer and an aperture coupled microstrip antenna (ACMA) as the feeding source. When the superstrate layer, microstrip patch, and coupling aperture are used properly and simultaneously, different resonance frequencies are produced, giving RL a broad frequency range. Additionally, only the superstrate layer created by the FSS layer with square loop elements can be used to produce high directivity. A wideband ACMA is initially created to function in the x-band. In this step, choosing the right coupling aperture design is crucial. An aperture coupled array antenna for X-Band application is presented. X-Band frequency range is from 8.0 to 12.0 GHz. The proposed antenna consists of two substrates with H shaped slot. In this research approach, we have used FR4 substrate with the dielectric constant of 4.4 and 0.02 loss tangent is used. The Aperture coupling feeding technique is used so that spurious radiation from the feed element is minimized. The return loss achieved for our proposed approach is -13dB for 8GHz and -27dB for 12GHz.The radiation performance such as VSWR, return loss, Radiation Pattern, and Gain, are analyzed and presented.
