Hi,
I am trying to find the S-parameters of a integrated Coplanar Waveguide using Agilent's Momentum tool... The signal line is on the top metal layer of a 9 metal stack and I have 2 GND lines running parallel to the signal conductor on both sides of it.
I define 4 ports : 1. Port 1 : Top of the Signal line 2. Port 2 : Bottom of the Signal line 3. Port 3 : Gnd line on the left 4. Port 4 : Gnd line on the right
I get a *.s4p from after my simulation. In my ADS schematic simulation, I connect Port 3 and Port 4 to the reference ground plane , and use the TL as a 2 port device.
Is there a way to accurately extract the S-parameters at a 2 port (*.s2p) from the EM simulations itself? In other words, is there a way to specify that the conductors on the sides of the signal line are GND lines, in the EM simulation. I need a 2-port S-matrix because I want to convert the S-parameters to ABCD to find out the Zo and gamma of the TL
Thanks!
