In recent years, Antenna and wireless communications have attracted much interest in the academic andindustrial worlds. In this paper, the design of microstrip patch antenna array with isolation by using square-slot twodecoupling structures including a row of Spiral EBG structure and three cross slots is proposed. Radiating patch lies onthe Roger RO3010, which is having high dielectric constant of 10.2 and loss tangent of 0.003. By changing the structuredimensions and the substrate materials, different bandgap characteristics can be obtained. The proposed antenna is fedwith coaxial probe. The simulation results show that the significant improvement in isolation of -38.95 dB and -45.98 dBis obtained by placing the proposed spiral EBG structure between the two square-slotted radiating patches. The proposedantenna enhances the return loss of -12.88 dB at the 4.5 GHz and -17.29 dB at 8.8 GHz frequencies. The obtainedfrequency is useful for C and X band applications. The proposed antenna were designed and simulated by using ANSYSHFSS (version 15.0).
