Measurement of Low-loss Dielectric Constant Based on Tangent Network Method
Guowen Ding · Research and Exploration in Laboratory · 2011
On the basis of the tangent network method,the waveguide unit filled with low-loss dielectric was identified with the tangent network,and the curve fitting method was used to work out network parameters,then the dielectric constant was derived.With microwave CAT(Computer Aided Test)system,the actual low-loss dielectric was measured,and the results agree well with the nominal value.
