# Coplanar waveguide gap

According to W.J.Getsinger [56] a coplanar series gap (see fig. 12.5) is supposed to be the dual problem of the inductance of a connecting strip between twin strip lines.

The inductance of such a thin strip with a width and the length is given to a good approximation by

where and . Substituting this inductance by its equivalent capacitance of the gap in CPW yields
