1. An wireless device, comprising:
- a substrate;
an antenna device formed on the substrate, comprising;
a ground electrode formed on the substrate;
a cell patch, wherein the cell patch comprises 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 electromagnetically coupled to the cell patch;
a via line coupled to the ground electrode; and
a via coupling the via line to the cell patch.

Abstract
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.
