    CST Field Contours bad resolution?

    Hi, I'm simulating a simple microstrip structure (picture). I tried different mesh-settings to have a better field resolution (looking at the e-field which seem to be kind of square-cut) but nothing changes. S-Parameter are also almost constant for even finer mesh. Is it a purely grafical issue...

    Grounding problem (ADS Momentum)

    Tried to figure out how to do that - where can I find that setting?

    Grounding problem (ADS Momentum)

    Hey there, Just started to do EM simulation with ADS Momentum. Simulation results of a simple microstrip line (lambda/4 @ ~90GHz) looks like this: I defined 2 Ports using 4 Pins for excitation. You can see the standing waves on the ground plane at all lambda/4. How can I solve this...

    Ideal Diode using SDD in ADS

    Hey there! I want to model an ideal diode in ADS using a SDD component! Zero current below threshold voltage Vth and zero resistence above. Can't be too difficult but I simply cannot figure it out (which is rediculous). Anyway, this is what I tried for the equ: " I[1,0] =if (_v1<0.7) then (0)...

    TRL Calibration Delay (non-zero thru)

    TRL Calibration (non-zero thru) Hey, I've already designed Thru, Line and Reflect Standards. Unfortunately I had to add some extra line in all 3 standards because of my general setup. Consequently, the reference plane is shifted. This means, that the Errorboxes (calculated by the TRL Matlab...
