Abstract

The microstrip patch resonator in several configurations can be used for determination of the dielectric constant and the loss tangent of materials available in sheet, paste and liquid forms. A suspended patch resonator was developed to determine the dielectric constant and loss tangent of wax, kerosene, petrol and vaseline. The measured dielectric constant of the sample is within ±2% and the loss tangent has a variation ±0.001 for the sample with moderate loss.
