A simple technique for characterization of dielectrics at high microwave frequencies is presented and demonstrated. The technique makes use of the measured impedance of a test structure. The latter is a simple capacitor; formed on the top of a substrate with an arbitrary number of dielectric/conductor layers and contains a material under test (MUT) layer with unknown loss tangent and dielectric constant. Assuming that all other layers are specified; a simple method is given to calculate RF impedance of such a structure enabling extraction of MUT properties.
