Abstract

Two types of split-cylinder resonators are used for characterization of the longitudinal dielectric parameters of reinforced RF substrates. The novelty of the method is the introduced theoretical 3D model of the measurement cavities, which allow determination of the parameters with the help of arbitrary 3D electromagnetic simulators. Two known isotropic and anisotropic materials are measured with circular and split-cylinder resonators and the results are compared. One of the considered structures - the split-coaxial resonator with movable inner post cylinder - allows substrate measurements at lower frequencies compared with the resonance frequency of the ordinary split-cylinder resonator.
