PLURAL PLANE WAVEGUIDE COUPLER ABSTRACT OF THE DISCLOSURE A quadrature hybrid coupler for coupling electromagnetic power between a first coplanar waveguide disposed on a first side of a circuit board and a second coplanar waveguide disposed on a second side of the circuit board is formed by means of a first pad and a second pad disposed in respective ones of the waveguides. The pads are formed as a widening of a central strip conductor of each of the waveguides. The pads are in registration with each other. Circumferential slots defining the pads are widened in proportion to a widening of the strip conductor to retain a characteristic impedance of the waveguides from ports of the coupler through the pads.
