"Classic" coplanar waveguide (CPW) is formed from a conductor separated from a pair of groundplanes, all on the same plane, atop a dielectric medium. In the ideal case, the thickness of the dielectric is infinite; in practice, it is thick enough so that EM fields die out before they get out of the substrate.

4.4.4 Coplanar Waveguide (CPW) Coplanar Waveguide (CPW)10 supports a quasi-TEM mode of propagation with the active metallization and the ground planes on the same side of the substrate. Each ‘side-plane” conductor is grounded and the center strip carries the signal; thus much less field enters the substrate when compared with microstrip.

The edge coupled differential microstrip transmission line is a common technique for routing differential traces. There are four types of impedance used in characterizing differential trace impedances De-Embedded Ports. Ports can now be de-embedded by specifying a port offset parameter, and the phase of the corresponding de-embedded S-parameters can be adjusted, based on the value of the port offset. De-embedded ports are useful, for example, to partition an assembly of microwave components in a different way than that of the original CAD model.

Why should we consider using coplanar waveguide over ground (CPWG)? It allows us to narrow the trace almost arbitrarily for a given layer thickness while maintaining a 50 or 75 ohm impedance. CPWG also allows less current into the air than a microstrip structure, because the topside ground copper shunts the field current locally to the topside ground.
