Antenna for wireless charging systems
First Claim
1. A metamaterial system of a wireless transmission apparatus comprising:
- a metamaterial layer comprising an array of unit cells, each of the unit cell including a surface having 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;
at least one input RF port disposed on a backing layer placed 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.

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.

16. A method of forming a metamaterial system, comprising:
-
forming a backing layer; forming a metamaterial layer from a metamaterial substrate, the metamaterial layer is formed above the backing layer; creating a plurality of partitions in the metamaterial layer, each of the plurality of partitions define a portion of a unit cell of a plurality of unit cells; creating an aperture in each of the plurality of partitions, the aperture is defined such that a periphery of the aperture is within a periphery of a partition in which the aperture is created by a spacing distance; disposing an element in the aperture of each of the plurality of partitions; forming at least one input RF port on the backing layer such that there is no short-circuit between the backing layer and the metamaterial layer; and connecting by at least one set of vias the plurality of unit cells with the at least one input RF port. - View Dependent Claims (17, 18, 19, 20)
