A Zero Index Based Meta-Lens Loaded Wideband Directive Antenna Combined With Reactive Impedance Surface

A Zero Index Based Meta-Lens Loaded Wideband Directive Antenna Combined With Reactive Impedance Surface

In this paper, an aperture efficient wideband high-gain patch antenna is designed using a novel multilayer-based metamaterial structure combined with a reactive impedance surface (RIS)-backed patch antenna. The metamaterial unit cell is a two-layer structure which is stacked one after other to form...
