US Patent 7501985 - Nanostructured tunable antenna

This patent from Motorola teaches an antenna formed by growing nanostructures on a substrate which provides the advantages of lower power consumption and a higher frequency range for mobile electronics devices. Claim 1 reads:

1. An antenna comprising:

a substrate comprising a material;

a plurality of nanostructures forming an antenna structure on the substrate, the nanostructures selected from one of the group consisting of nanotubes, nanowires, nanorods, and nanobelts; and

a radio frequency signal apparatus comprising a dielectric waveguide formed within the substrate, a coupling between the radio frequency signal apparatus and the plurality of nanostructures consisting of electromagnetic waves-through the material of the substrate.
