In the present work, the measurement cell for investigation of small-volume liquids in sub-THz range is proposed. The proposed measurement cell is based on the whispering-gallery mode quartz resonator covered with the plastic layer comprising the microfluidic channel and allows obtaining the complex permittivity of the liquid filling the microfluidic channel. Investigation of the resonator structure was carried out experimentally and using the numerical model of the structure. It is shown that the resonator structure can be used as a measurement cell with additional calibration procedure.
