  • Patent number: 8760240
    Abstract: A miniaturized (compact) millimeter wave hybrid based on a coupling function and associated method for designing millimeter wave electrical elements based on a coupling function is provided. The invention overcomes a drawback of conventional coupled transmission lines structures and equivalent lumped elements in that they are considerably large in size for IC designs making such structures unsuitable for use in RFICs' designs. Hence, such structures are not partial in millimeter wave electrical elements, and more particularly elements that should be integrated in devices for 60 GHz applications.
