Abstract:

A gas sensor for detecting a gas in an environment is disclosed. The gas sensor comprises a housing having a cavity and a vent hole within the housing and a distributed element resonator within the cavity. The cavity includes a bottom surface and a top surface, and the housing is configured to receive the gas from the environment into the cavity through the vent hole. The distributed element resonator has an input terminal configured to receive a radio frequency input signal and an output terminal configured to produce an output signal.
