Measurements of complex permittivity of low loss dielectric materials (especially anisotropic) in a wide range of temperatures still represent a challenging issue. For bulk samples Whispering Gallery Modes can be used, but planar dielectrics can only be measured using TEol1 and TE018 resonators. Accuracy of tanO measurements is also determined by accuracy in determination of unloaded Qo-factor of test fixtures. This paper presents a review of resonators, a precise technique to measure the Qo factor and measurement results of complex permittivity of several low loss dielectrics.
