Directional coupler in coplanar waveguide technology for measuring applications, has spacing between two internal conductors exponentially increasing at coupling path along longitudinal direction

摘要

A first internal conductor (107) connects two terminals (103,104), and a second internal conductor (108) connects an output terminal (106) and a termination (105). The spacing between two internal conductors (107,108) varies, e.g. exponentially increases, at a coupling path along the longitudinal direction of the internal conductors.
