Trace Analyzer Benchmark of a Single Microstrip

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

The parameters for the stripline are given below:

  • w = 10 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

Z0 (ohm)

measurement

53

*LINPAR

53.82

Trace Analyzer

53.55

* 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.
