Application of a Dielectric Resonator on Microstrip Line for a Measurement of Complex Permittivity

This item was taken from the IEEE Periodical ' Application of a Dielectric Resonator on Microstrip Line for a Measurement of Complex Permittivity ' A cylindrical dielectric resonator placed on microstrip line is used for measuring the complex permittivity of microwave low-loss high epsilon/sub r/ dielectric materials. The method is based on the accurate solution of this resonator with TE/sub 01delta/ mode and is compared to the method of dielectric rod resonator with TE/sub 11/ mode. The accuracy of the both method is similar - the measurement accuraoy of relative dielectric constant is better than 0.2 percent and measurement accuracy of loss tangent is about 1�10/sup -4/.
