A new hybrid method for mutual coupling minimization of an antenna array

<span lang="EN-US">In this paper, a simultaneous application of geometric modification on patch elements and electromagnetic band gap (EBG) bandgap structures (hybrid method) has been suggested for 3.5 GHz wireless communication applications, to minimize the mutual coupling between radiating microstrip array antennas. The EBG slotted structure is composed one square ring three squares placed Rogers RO3010 having 10.2 h=1.27 mm which presents respectively its dielectric constant thickness. In approach, are geometrically modified, while also employing structures, formed by four cells, at near distance. geometry antenna introduction reduces an with approximately 33 dB hand improves gain 0.43 other hand. Initially, slots introduced in then unit cells inserted two patches, operating GHz. design parameters were optimized.</span>
