1. A device, comprising:
- a dielectric substrate having a first surface on a first side and a second surface on a second side opposing the first side;
a plurality of conductive patches formed on the first surface and separated from one another;
a ground conductive layer formed on the second surface; and
a plurality of conductive via connectors formed in the substrate to connect the conductive patches to the ground conductive layer, respectively, to form a plurality of unit cells each comprising a volume having a respective conductive patch on the first surface, and a respective via connector connecting the respective conductive path to the ground conductive layer;
wherein the device is structured to form a composite left and right handed (CRLH) metamaterial structure from the unit cells;
wherein the ground conductive layer is patterned to have a dimension underneath a respective conductive patch to be less than a dimension of the respective conductive patch; and
wherein the ground conductive layer comprises a strip line that is connected to the conductive via connectors of at least a portion of the unit cells and passes through underneath the conductive patches of the portion of the unit cells, and wherein the strip line has a width less than a dimension of the conductive patch of each unit cell.

Abstract
Techniques, apparatus and systems that use one or more composite left and right handed (CRLH) metamaterial structures in processing and handling electromagnetic wave signals. Antenna, antenna arrays and other RF devices can be formed based on CRLH metamaterial structures. The described CRLH metamaterial structures can be used in wireless communication RF front-end and antenna sub-systems.
