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