Trace Analyzer Benchmark of Couled Striplines

NEW! Download the feature-rich application version of the trace analyzer.

The parameters for the stripline are given below:

w = 11.7 um
s = 6.4 um
b = 25.4 um
t = 1.4 um
er = 3.25

Characteristic impedance values computed by FlexPDE, a finite element (FEM) tool, and LINPAR, a method of moment (MOM) tool, are listed below:

Method	Zodd (ohm)	Zeven (ohm)
FlexPDE	41.05	60.56
*LINPAR	40.82	59.75
Trace Analyzer	40.94	60.40

* NOTE: Since Trace Analyzer applet only evaluate the lossless parameters, LINPAR is configured to report only the L/C matrices in order to have to fair comparison.

A specialized version of Trace Analyzer is shown below. User can verify the result by using menu Calculate::Impedance and use it as a template to solve similar problems.
