Abstract
A mechanism for coupling a coaxial cable () to a planar circuit to provide galvanic isolation between the coaxial cable and the planar circuit while providing low transmission loss and reflections between the coaxial cable () and the circuit. The mechanism comprises a co-planar waveguide () coupled to the coaxial cable (), a microstrip line () connected to the circuit, a galvanic isolation component () and a ground plane (). The co-planar waveguide (), the microstrip line () and the galvanic isolation component () are formed on one side () of a two-sided substrate (). The ground plane () is formed on the other side () of the substrate () and underlies at least a portion of the co-planar waveguide () to form a grounded co-planar waveguide (). The ground plane () includes a notch () underlying a portion of the co-planar waveguide () to provide a transition region () from the co-planar waveguide () to the grounded co-planar waveguide ().
