Abstract

In this paper is reported the development of microstrip resonators working in the frequency range of 3–6 GHz and their employment in the investigation of the sensing properties of nanostructured materials towards gas. The materials are deposited as films on the gap of the resonators by drop coating aqueous solutions of Ag@α-Fe2O3 nanocomposite having a core–shell structure. Here are reported sensing data about humidity monitoring in the range from 0 to 70%. The increase of humidity value brings to a large frequency shift of the resonance one. The good characteristics of the fabricated device suggest its promising use as humidity sensor.
