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.
