Microwave antenna with integrated function of sensor of organic vapors

摘要

The present invention relates to a microwave antenna with integrated function of an organic vapor sensor, particularly an antenna of a microstrip arrangement with a ground plane, intended for transmission of information in wireless networks. The second function of the antenna is a possibility of detection of organic vapors. The antenna of the present invention consists of a substrate (1) of electrically non-conducting material in the form of a flat figure, having coated on its surface an electrically conducting functional layer (2) with a capacity of reception/transmission of a signal and simultaneously a reversible adsorption/desorption of organic vapor molecules. The functional layer (2), constituted on the base of a randomly entangled nanotubes, is a product of a vacuum filtration of dispersion of carbon nanotubes through a filtration membrane of polymeric nanofibers either as a self-supporting functional layer or with an integrated filtration membrane, which remains the part of the formed functional layer.
