The application of carbon nanotube CNT materials to produce lightweight, flexible, and durable alternatives to existing and future Army antenna designs is explored through fabrication and measurement of a variety of CNT thread and sheet antenna designs. A variety of CNT threadrope dipole and loop antennas are fabricated, measured, and compared with a standard copper dipole antenna. An aperture-coupled patch antenna composed of CNT sheet material, is fabricated, measured, and compared with a standard copper patch antenna. Finally, a meshed patch antenna composed of interwoven CNT threads is developed and simulated as a concept for a multifunctional communications antenna and reactive gas sensor.
