Hello everyone:
I have an issue with understanding which set of S-parameters should I use from CST MWS simulation of a CBCPW 50 ohm line. I come from an ADS background (both Momentum as well as Schematic), and CST is fairly new to me.
I want to test a CBCPW 50 ohm line up to 300GHz. I saw that by default in the transient solver, in Specials, there is an Option AR-Filter which is set to on. When finishing the simulation, in 1D results pallete I don't have only S-Parameters block but as well S-Parameters(AR). Which is the difference between the two, as the results are not exactly identical (very similar but not identical)? Which of the 2 should I consider? S-parameters or S-parameters (AR).
I want to mention that I use GaAs, 100um thickness. with lateral top GND width of 100um to avoid as much as possible resonant patch-like behaviour. The waveports are defined with lateral dimensions to be on the lower limit, such that higher order modes don't get excited.
Any feedback on which set of S-parameters should I consider (S-Parameters vs. S-Parameters(AR)) is greatly appreciated!
Thanks in advance to all,
George.
