Abstract

A meshed patch antenna fabricated with carbon nanotube thread is proposed for multiple applications, including communications and chemical/gas sensing. Full wave simulation results of the meshed patch antenna are presented to demonstrate its use as a communications antenna and to predict its performance as a chemical/gas sensor. The patch antenna exhibits a center frequency of 27.85 GHz with a −10 dB bandwidth of 2.1 GHz (7.5%). The patch center frequency shifts approximately 60 MHz in direct response to the change in carbon nanotube permittivity that occurs due to the presence of a reacting gas.
