Abstract:
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.
