Thanks for the reply
Below is the 3-D geometry As said by you
I generated scattering parameters for the above geometry.
scattering parameters generated by above geometry were taken into line-sim to introduce the effect of ac coupling capacitors and then i saw insertion and return loss profile
I took capacitor as 100nF and shorted it with resistor od
But whether i take capacitor as 100 nF or remove that capacitor with 0 ohms same graph was observed for return and insertion loss, i think in line-sim also it is not taking capacitor into consideration.
Can you help me with this?
