An apparatus ( 10, 30, 40, 50 ) 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 ( 16 ), e.g., carbon nanotubes, forming an antenna structure on a substrate ( 12 ), and a radio frequency signal apparatus formed within the substrate ( 12 ) and coupled to the plurality of nanostructures ( 16 ). The radiation element length of a nested multiwall nanotube ( 161 ) of an exemplary embodiment may be tuned to a desirable frequency by an electromagnetic force ( 163 ).
