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.

Abstract: Apparatus and techniques that provide tuning elements in antenna devices to tune frequencies of the antenna devices, including composite right and left handed (CRLH) metamaterial (MTM) antenna devices. Examples of the tuning elements for CRLH MTM antenna devices include feed line tuning elements, cell patch tuning elements, meandered stub tuning elements, via line tuning elements, and via pad tuning elements tuning elements that formed near corresponding antenna elements such as the feed line, cell patch, meander stub, via line and via pad, respectively.

Abstract: A variety of configurations for a CRLH structured antenna in a wireless device are presented. An antenna having portions of the CRLH structure positioned on different layers provides an elevated structure. An antenna is presented having a double folded antenna structure, wherein a cell patch includes extensions on multiple layers of a substrate.
