When using a substrate with the relative permittivity "er" set to 1.0, the S-Parameter Simulation yields only results with "NaN". See below for an example schematic.
I had a look at the equations of t…

Dear Homer,
the documentation describes the EdgeFedAntenna example with port definition as EFAntenna.ports file.
Trying this example gives 'error: EFAntenna.ports:2: unknown keyword POSITIVE (aborti…

EDIT: loss formulas for CPW at see http://qucs.sourceforge.net/tech/node86.html use different units - this is confusing
In the cpwline.cpp it looks like the conductive losses are calculated as if t…
