ABSTRACT:
A directional microwave coupler with, on one face of a substrate of dielectric material, an arrangement of conductive zones and strips forming two coplanar lines. The central conductive strips of the coplanar lines continue into other conductive strips, with a transverse conductive strip forming an electrical connection between the central conductive strips of the coplanar lines and the other conductive strips. The second face of the substrate of dielectric material opposite from the first face is provided with a conductive underlay which is coupled electrically to a central conductive zone common to the coplanar lines. The conductive underlay in conjunction with the other conductive strips forms microstrip lines.
