  • Constant impedance transition between transmission structures of different dimensions
    Patent number: 5184095
    Abstract: A microstrip transmission line structure a series of connected microstrip strip sections having different widths disposed on an outside layer of a unitized multilayer circuit structure and forming a microstrip line, respective ground planes for each of the strip sections formed between insulating layers of the untilized multilayer circuit structure and respectively spaced from the associated strip sections to provide a substantially constant impedance along the length of the microstrip line, and a plurality of conductive vias for electrically interconnecting the respective ground planes.
