    Abstract: A quadrature coupler having: a pair of overlying strip conductors separated by a first dielectric layer to provide a coupling region between the coupling region of overlying strip conductors; a pair of opposing ground pads, the coupling region being disposed between the pair of opposing ground pads; a second dielectric layer disposed over the coupling region and between the pair of opposing ground pads; and an electrically conductive shield layer disposed over the second dielectric layer, extending over opposing sides of the dielectric layer and onto the pair of opposing ground pads. Portions of coupler are formed by printing or additive manufacturing.

    Abstract: A microwave transmission line structure having a pair of ground strip conductors on a surface of a dielectric substrate structure. A signal strip conductor is disposed on the surface of the dielectric substrate structure between the pair of ground strip conductors. A solid dielectric layer is disposed over: the signal strip conductor; the upper surface of the dielectric substrate structure between sides of each one of the ground strip conductors; and the signal strip conductor. An electrically conductive shield member is disposed on the solid dielectric layer and on, and in direct contact with, upper surfaces of the pair of ground strip conductors. The structure is used on each one of a plurality of proximate microwave transmission lines formed on the substrate structure to electrically isolate the transmission line.
