Abstract: This article presents a 3D-metamaterial (3D-MTM) structure to enhance microstrip patch antenna gain. A 3D-MTM unit cell exhibits an MNG (µ-negative) property with a high negative refractive index over the 2.36-2.53 GHz frequency range resonating at 2.45 GHz. Therefore, a 4×4 array of the proposed 3D-MTM unit cell is analyzed and used as a superstrate over a patch antenna and a 2×2 array antenna to achieve high gain for wireless applications. The simulated and measured results of the designed antenna show that … Show more
