the coplanar waveguide simulation in HFSS

Hi, I have a simple question about the coplanar waveguide simulation in HFSS. How do I define the "port" for a non-ground CPW?

And in reality, how can I connect the coaxial cable to the CPW? Can I connect the inner conductor to the central strip and the outer conductor to one side of the side ground?

There is JPEG-drawing, with cpw-port for HFSS model, at the next topic:

You need to connect Outer conductors to both sides of the cpw-ground.
