An antenna includes a planar dielectric substrate having opposing first and second surfaces, a ground plane disposed at the first surface, the ground plane composed of conductive material, a radiating plane disposed at the second surface and composed of conductive material. The radiating plane implements a plurality of unit cells, with each unit cell having a corresponding section of the conductive material of the radiating plane that is formed in a specified shape, the specified shape including a first portion forming a load inductor and second portion forming a radiating patch electrically coupled to the load inductor. Each unit cell further includes at least one via electrically coupling the load inductor to the ground plane.
