Development and Evaluation of a Characteristic Impedance Calculator

Abstract

This paper presents our development and evaluation of a transmission line characteristic impedance calculator that offers visualization and immediate feedback. Several impedance calculators based on closed-form equations are reviewed in terms of their functionality, accuracy and validity. Two example problems from our calculator are then presented to show how our calculator operates. The accuracy of our calculator for characteristic impedance and per-unit-length capacitance and inductance compares well with that of a commercial 2-D field solver for a range of geometries such as microstrip, stripline, embedded microstrip and asymmetric stripline. Our calculator is written in Matlab and its executable program will be made available on the internet.
