This paper is about the design and the realization of a one-port microwave microstrip resonator working in the frequency range from 3 GHz to 6 GHz and its metrological evaluation in order to be employed as a gas sensor. The prototype can be tailored towards a gas target by depositing an appropriate sensing layer of a nanostructured material. The sensor device is achieved by depositing the sensing material as film layer just on the gap of the resonator. Here, the analysis is focused on an Ag@α-Fe2O3 nanocomposite-based microstrip resonator used for sensing the relative humidity that is varied in the range from 0% to 75%. The increase of humidity value brings to a frequency shift in the two resonances observed in the measured reflection coefficient. The characteristics of the fabricated device suggest its promising use as humidity sensor.

Abstract

This paper is about the design and the realization of a one-port microwave microstrip resonator working in the frequency range from 3 GHz to 6 GHz and its metrological evaluation in order to be employed as a gas sensor. The prototype can be tailored towards a gas target by depositing an appropriate sensing layer of a nanostructured material. The sensor device is achieved by depositing the sensing material as film layer just on the gap of the resonator. Here, the analysis is focused on an Ag@α-Fe2O3 nanocomposite-based microstrip resonator used for sensing the relative humidity that is varied in the range from 0% to 75%. The increase of humidity value brings to a frequency shift in the two resonances observed in the measured reflection coefficient. The characteristics of the fabricated device suggest its promising use as humidity sensor.
