This part of IEC 61189 outlines a way to determine the relative permittivity ( r) and loss tangent (tan ) (also called dielectric constant (Dk) and dissipation factor (Df)) of copper clad laminates at microwave frequencies (from 1,1 GHz to 20 GHz) using a split post dielectric resonator (SPDR).
This part of IEC 61189 is applicable to copper clad laminates and dielectric base materials
