Waveguide type dielectric resonators - Part 1-5: General information and test conditions - Measurement method of conductivity at interface between conductor layer and dielectric substrate at microwave frequency
Microwave circuits are popularly formed on multi-layered organic or non-organic substrates. In
the microwave circuits, the attenuation of planar transmission lines such as striplines,
microstrip lines, and coplanar lines are determined by their conductor loss, dielectric loss and
radiation loss. Among them, the conductor loss is a major factor in the attenuation of the
planar transmission lines. A new measurement method is needed to evaluate the conductivity
of transmission line on or in the substrates such as the organic, ceramic and LTCC (low
temperature co-fired ceramics) substrates.
