The changes in the transmission modulus and phase of the propagating microwave signals in a micromachined coplanar waveguide supported on a dielectric membrane filled with a mixture of carbon nanotubes when exposed to nitrogen gas are examined. The large shifts of amplitude and phase of microwave signals due to gas absorption have represented a basis on which a miniature wireless gas sensor is implemented.
