Highly sensitive dielectric resonator sensor for liquid characterization

Abstract

This article describes a novel 2 GHz dielectric resonator sensor (DRS). The dielectric resonator is made of ceramic material and is fed by a microstrip transmission line, using the aperture-feeding method. The sensor shows a high quality factor (Q-factor) with an associated high resolution. As a test, the sensor is used in an application for the characterization of liquid solvents such as Glucose and Ethanol at different concentrations.
