Abstract
The present disclosure describes antennas based on a conductive polymer composite as replacements for metallic antennas. The antennas include a non-conductive support structure and a conductive composite layer deposited on the non-conductive support structure. The conductive composite includes a plurality of carbon nanotubes and a polymer. Each of the plurality of carbon nanotubes is in contact with at least one other of the plurality of carbon nanotubes. The conductive composite layer is operable to receive at least one electromagnetic signal. Other various embodiments of the antennas include a hybrid antenna structure wherein a metallic antenna underbody replaces the non-conductive support structure. In the hybrid antennas, the conductive composite layer acts as an amplifier for the metallic antenna underbody. Methods for producing the antennas and hybrid antennas are also disclosed. Radios, cellular telephones and wireless network cards including the antennas and hybrid antennas are also described.
