It seems as though the equivalent resistance of the device is going to be the "R" in the lowpass filter equation. By putting a single capacitor in shunt with the device a filter is created. A single capacitor model just adds a phase shift of +/- 90 degrees to your voltage/current.
Dear Skan,
CST (and HFSS) are electromagnetic field solvers. For microstrip lines the waveport needs to be much larger than the width of the line in order to capture the fields so it can make the correct calculations. Try doing a parametric study of a microstrip line where you vary the port...
Dave,
My office mates and I tried that with a wave port and a lumped port, but the result deviated from theory too much. My guess is that it has something to do with having a wave port at the boundary. I'll try to remember to post a picture of the final VSWR that I got tomorrow.

One of my office mates found the solution. The impedance boundary is defined by square, which means that you have to make a square - not a rectangle. The two words are sometimes used interchangeably. What this means is that in HFSS whatever shape that is drawn is not set to the impedance that...
Hello,
I am currently building a demo of a microstrip line with a tuning stub. The transmission line is terminated in a load impedance of 100-50j ohms. The microstrip line has a Z0 of 50 ohms, and the stub has a Z0 of 100 ohms. I know my designs for the microstrip lines work, but I am having...
