Characteristic Impedance Determination Using Propagation Constant Measurement

Published

Author(s)

Roger Marks, Dylan F. Williams

Abstract

A method is demonstrated where by the characteristic impedance of transmission lines may be easily determined from a measurement of the propagation constant. The method is based on a rigorous analysis using realistic approximations to account for the effects of imperfect conductors. Numerical studies indicate that high accuracy is possible, and experiments using coplanar waveguide demonstrate the advantage of the method in the interpretation of S-parameters.
