Abstract
An apparatus () is provided that relates to nanotubes as radiation elements for antennas and phased arrays, and more particularly to a macro-sized RF antenna for mobile devices. The antenna comprises a plurality of nanostructures (), e.g., carbon nanotubes, forming an antenna structure on a substrate (), and a radio frequency signal apparatus formed within the substrate () and coupled to the plurality of nanostructures (). The radiation element length of a nested multiwall nanotube () of an exemplary embodiment may be tuned to a desirable frequency by an electromagnetic force ().
