Resonator method: Split cylinder resonator for permittivity measurement 10 GHz-80 GHz
Easy to use mm wave low loss dielectric test
- Ideal for evaluating low loss dielectric materials with tan δ 0.01 or less
- Easy and reproducible dielectric material measurement in millimeter wave band with excellent fixture design
- Unique excitation mechanism extends the upper limit frequency to 80 GHz
The millimeter wave material market is changing drastically by 5G and automotive radar.
A measurement system that can evaluate leading edge materials accurately is needed to succeed in the market.
The 80 GHz split-cylinder resonator responds to this market demand and provides easy-to-use and accurate dielectric material measurements.
Our split cylinder has been very well established up to 50 GHz, and the resonator design has been optimized according to the latest machining technology
to extend the upper frequency towards 80 GHz. As a result, it has become possible to accurately and easily measure low loss dielectric materials
in a wide frequency range from 10 GHz to 80 GHz using a flat plate sample.
