How to Feed a Grounded Coplanar Waveguide

A method is presented on how to feed a grounded coplanar waveguide (GCPW) in CADFEKO. The same method can be used to feed a coplanar waveguide (CPW).

A grounded coplanar waveguide consists of a signal conductor placed between ground conductors but separated by slots. The conductors are fabricated on top of a dielectric substrate with a conductive ground plane at the bottom.
