Faqs
How do you calculate the characteristic impedance of a microstrip, stripline, or coax?
When using waveguide ports in the simulation project, there is a solver setting named ‘calculate port nodes only.’
When this is activated, only the port modes will be calculated, which makes the simulation run quickly.
The results are found in the ‘navigation tree,’ either in 1D results/port information/line impedance or in 2D/3D results/port modes/port1/e1.
When running the full simulation, it is also possible to use TDR (time domain reflectometry) to analyze the impedance vs. time.
