1. A wireless transmission apparatus comprising a rectangular patch antenna array including antennas mounted on a substrate comprising a plurality of unit cells having rectangular inductive spiral loops embedded uniformly and uni-directionally within a host dielectric substrate so as to form a magnetic permeability enhanced metamaterial, said unit cells being uniformly stacked on each other to form a three-dimensional resonance structure that is oriented orthogonally to a magnetic field of said antennas, where dimensions of said rectangular inductive spiral loops are selected whereby said metamaterial has a resonance frequency that matches a resonance frequency of said antennas.
