An antenna device, such as composite right and left handed (CRLH) antenna device, is formed on the substrate, including a ground electrode formed on the substrate. In an example, the antenna device includes a cell patch comprising an enclosed conductive portion formed along an exterior edge of the cell patch, leaving an interior portion of the cell patch to partially expose the substrate. A feed structure is electromagnetically coupled to the cell patch, a via line is coupled to the ground electrode, and a via couples the via line to the cell patch.
