Ports for Coplanar Waveguide Simulation

[sv1437]

Hi,
For defining the ports for coplanar waveguide simulation in HFSS, I followed the ports dimensions as given inHFSS handbook. ie., Port height is atleast 4h and Port width atleast 3-5g and port outline intersects side grounds. I was able to simulate, but I have a question:

Since the waveport is touching the side ground planes, Are the gound planes also excited along with the signal conductor ? and How to make sure that the ground planes are not excited.

Thanks in advance,
sv
