Abstract
A metamaterial system of a wireless transmission apparatus comprises a metamaterial layer. The metamaterial layer comprises an array of unit cells wherein each of the unit cell comprises a surface having a metal patch with an aperture. The aperture is defined such that a periphery of the aperture is within a periphery of the surface by a spacing distance and an element is disposed within the aperture. The metamaterial system further comprises at least one input RF port placed on a backing layer disposed below the metamaterial layer such that there is no short-circuit between the conductive backing layer and the metamaterial layer; and at least one set of vias connecting the array of unit cells with the at least one input RF port.

A wireless transmission apparatus comprising:
- a metamaterial layer including a unit cell, wherein the unit cell includes a surface having a metal patch with an aperture, the aperture is defined such that a periphery of the aperture is within a periphery of the metal patch by a spacing distance, and an antenna element is disposed within the aperture.
A method of forming a unit cell comprising:
- forming a metamaterial layer using a metamaterial substrate;
- creating a surface on the metamaterial layer;
- creating a metal patch with an aperture in the surface of the metamaterial layer;
- and
- disposing an antenna element in the aperture to form the unit cell.
