Ground Plane in RF Module

I have looked over most of the tutorials and have never seen how to define a ground plane using the RF Module in COMSOL. I am currently working on simulating a CPW in COMSOL, but am not sure whether or not my model is accurately simulating the finite-width ground planes on each side of the conductor.

Right now, I use two coaxial ports, similar to the Balanced 6 Ghz Patch Antenna tutorial, where one is used as the excitation port, and the other is just a port but the "Excitation at this port" box is *not* selected. The idea is that the port with no excitation might absorb some of the RF energy, but I have no idea whether this is the correct way to go about it.

I think that using the "Lumped Port" boundary condition might allow a ground plane, since this is used in the strained PCB filter tutorial, but can the analogue of a ground plane be done using the "Port" boundary condition?
