An experimental prototype of the near-field microscope based on the coaxial microwave resonator and a vector network analyzer R&S ZVA 24 is described. The results of test measurements of the shift of the resonance frequency and the quality factor of the resonance curve with the use of bulk conductors made of metals of different conductivity are presented. It is shown qualitatively that the resonant frequency and the quality factor decreases as the probe approaches the surface of the conductor. Q–value is minimal when using a conductor with the lowest conductivity.
