This standard BS EN IEC 63185:2021 Measurement of the complex permittivity for low-loss dielectric substrates balanced-type circular disk resonator method is classified in these ICS categories:
33.120.30 RF connectors
IEC 63185:2020 relates to a measurement method for complex permittivity of a dielectric substrates at microwave and millimeter-wave frequencies. This method has been developed to evaluate the dielectric properties of low-loss materials used in microwave and millimeter-wave circuits and devices. It uses higher-order modes of a balanced-type circular disk resonator and provides broadband measurements of dielectric substrates by using one resonator, where the effect of excitation holes is taken into account accurately on the basis of the mode-matching analysis.
