IMPEDANCE-CONTROLLED COPLANAR WAVEGUIDE SYSTEM FOR THE THREE-DIMENSIONAL DISTRIBUTION OF HIGH-BANDWIDTH SIGNALS

摘要

The invention relates to a waveguide system for distributing high-bandwidth signals in a multilayer circuit carrier. The waveguide system comprises at least one coplanar waveguide (2) and one or more ground wires (3, 4). The coplanar waveguide (2) is disposed with the ground wires (3, 4) associated therewith between at least two insulating layers (5, 6) of the circuit carrier. The surface of the two insulating layers oriented away from the plane of the waveguide (2) has electrically conductive layers (7, 8). Electrically conductive plated through-holes (9, 10) extend along the waveguide (2) substantially perpendicular to the plane of the waveguide. The ground wires (3, 4), the electrically conductive layers (7, 8), and the plated through-holes (9, 10) are electrically connected to ground potential. The waveguide system serves particularly for the three-dimensional distribution of high-bandwidth signals.
