A measurement platform for microwave characterization of liquids is presented. Coaxial probes using evanescent near-fields are designed and realized to mitigate the lack of spatial resolution of conventional open-ended coaxial probes. The liquid under test is placed on a XYZ piezo-based positioning stage with nanometer displacement resolution. The proposed solution is a viable candidate to address quantitative dielectricimaging in the frequency range 100 kHz to 53 GHz. The experimental preliminary results considering characterization of liquid droplets using an approach-retract configuration are presented and demonstrate the viability of the approach proposed.
