1. A wireless device having a Composite Right and Left Handed (CRLH) antenna structure, comprising:
- a substrate including at least planar metallization layer comprising;
a cell patch;
a feed line capacitively coupled to the cell patch;
a meander line coupled to the feed line; and
a conductive line coupling the cell patch to a reference voltage; and
a conductive structure coupled to the feed line, configured to extend in three dimensions including outside a plane of the metallization layer, the conductive structure configured to bridge a first location to a second location on the meander line and configured to increase an effective length of the meander line,wherein the meander line and the conductive structure are configured to provide a first right-handed (RH) mode resonance established by the effective length of the meander line; and
wherein the cell patch and the conductive line are configured provide a left-handed (LH) mode resonance.

9. A method for forming a Composite Right and Left Handed (CRLH) antenna structure, comprising:
-
forming a first planar metallization layer on a substrate, the first metallization layer comprising; a cell patch; a feed line capacitively coupled to the cell patch; and a meander line coupled to the feed line; forming a conductive structure coupled to the feed line, configured to extend in three dimensions including outside respective planes of the metallization layers, and configured to increase an effective length of the meander line; and forming a second planar metallization layer on the substrate, the second metallization layer comprising a conductive line adapted to couple the cell patch to a reference voltage, wherein the meander line and the conductive structure are configured to provide a first right-handed (RH) mode resonance established by the effective length of the meander line; wherein the cell patch and the conductive line are configured provide a left-handed (LH) mode resonance; and wherein the conductive structure is a bridge structure coupling one part of the meander line to another part of the meander line. - View Dependent Claims (10, 11, 12, 13, 14, 17)
