Abstract:
A broadband transmission line interconnection device, the device comprising:a first transmission line having a first ground on a first plane; and a second transmission line having a second ground on a second plane, wherein the second ground shape is geometrically configured to interact with the first ground for maintaining a uniform desired characteristic impedance for broadband micro-wave signal propagation between the first and second transmission line; a substrate having the first transmission line defined at a first side on a first surface, the first transmission line including a signal conductor and at least one ground conductor for providing the first ground, a signal conductor at the second transmission line defined on an opposite side of the first surface, and the second ground of the second transmission line on an opposed surface, the signal conductor of the first transmission line being electrically connected to the signal conductor of the second transmission line on the first surface; and the second around of the second transmission line, on the opposed surface, having at least one protrusion aligned with the signal conductor of the first transmission line.
