Trace Analyzer Benchmark of Coupled Microstrips

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

The parameters for the stripline are given below:

w = 10 mil
s = 5 mil
t = 2.8 mil
h = 8 mil
er = 5.23

Characteristic impedance values from measurement, and LINPAR, a method of moment (MOM) tool, are listed below:

Method	Zodd (ohm)	Zeven
*LINPAR	38.47	65.67
Trace Analyzer	38.41	65.31

* 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.
