In this research work, the gain of a square shaped microstrip antenna has been enhanced using an electromagnetic bandgap (EBG). The dimension of the proposed antenna is 57x57x1.6 mm3. The proposed square patch antenna is simulated using commercially available FR4 substrate whose dielectric constant is about 4.7. The proposed antenna resonates at ISM band of 2.45 GHz. The antenna is powered by 50Ω transmission line using the microstrip feedline structure. The gain of this antenna is improved by 3.5 dBi from that of a conventional antenna. The antenna parameters such as radiation pattern, return loss, VSWR and gain have been evaluated. The antenna is designed and simulated on Computer Simulation Technology (CST) microwave studio.
