Nanopatch antennas and related methods for enhancing and tailoring are disclosed. According to an aspect, an apparatus includes a conductive material defining a substantially planar surface. The apparatus also includes a conductive nanostructure defining a substantially planar surface. The conductive material and the conductive nanostructure are positioned such that the planar surface of the conductive material faces the planar surface of the conductive nanostructure, such that the planar surfaces are substantially parallel, and such that the planar surfaces are spaced by a selected distance. The apparatus also includes an optically-active material positioned between the planar surfaces.
