Abstract

This article presents a metasurfaced patch antenna in which the metasurface acts as a superstrate/cover placed atop a 2.45-GHz patch antenna, at a small distance. The metasurface is a Mu-near-zero (MNZ) type, which gives a near-zero index of refraction. The MNZ metasurface consists of 4 x 4 double-closed-loop resonators printed on a thin FR4 dielectric slab. The proposed antenna is low-cost and low-profile, having overall dimensions of 0.86 Î» x 0.86 Î» x 0.07 Î». The simulation and experimental results confirm that the metasurfaced antenna not only has simultaneous enhancements on broadside gain and bandwidth, but also improves antenna efficiency.
