Hello,
I am simulating an inter digital capacitor (**broken link removed**) with ADS and am trying to determine it's capacitance from the S parameters.
The structure is simulated on a 1.5mm FR4 substrate with ground plane using the FEM simulator. The FEM simulator requires a ground plane.
Using S11, converting it to Y11 to get the capacitance is not a problem, but using this technique, one half of the structure is connected to ground. This influences the simulation result, because the ground plane is also connected to ground.
I was wondering if I could get the actual capacitance between the two ports, eliminating the groundplane's influence. Can anyone help me?
