I have tried with the usual value 5.8e7 S/m: The level is a little superior, but it is also inferior to the measurement. I don't think it is a principal reason.
I have assigned the conductors (Copper adhesive tape) as Finite Conductivity Boundary with the conductivity 2e7 S/m. The substrate is synthetic paper and there is a adhesive layer between the substrate and the conductors. The waveport is renormalized to 50 ohm.
Dear volker@muehlhaus,
Could you explain in detail, I really don't know this part. I have measured with an OSLT calibration that includes the connectors losses due to the transitions between the input-output coaxial cables and the cpw line. I think S21 simulation level must be slightly superior...
Hello,
I would like to simulate a simple CPW line on a large band of frequency 0-20 GHz. I have created the excitation waveport and the boundary as the same as the CPW tutorial.

The E-field on waveport is ok...
