Abstract:
1. A transmission line for transmitting both high-frequency differential signals and power, comprising: a dielectric body having a preselected length that extends between two opposing ends and having a preselected width, a first pair of conductive traces disposed on the exterior of the dielectric body, one of the traces of the first pair of conductive traces carrying a positive differential signal and another of the traces of the first pair of said conductive traces carrying a negative differential signal when said transmission line is energized, the first pair of conductive traces being spaced apart from each other by a given distance along the length of said dielectric body between the two ends thereof, said first pair of conductive traces being aligned with each other so as to permit capacitive coupling therebetween along said dielectric body, and a second pair of conductive traces disposed on the exterior of said dielectric body for carrying power when said transmission line is energized, the second pair of conductive traces being spaced apart from each other by a given distance along the length of said dielectric body between the two ends thereof, said second pair of conductive traces being aligned with each other so as to permit capacitive coupling therebetween along said dielectric body, said first and second pairs of conductive traces being spaced apart from each other by a sufficient distance to deter coupling between said first and second pairs of conductive traces, said dielectric body having at least first and second grooves disposed on said dielectric body exterior, each of the first and second grooves including a pair of side walls spaced apart from each other by an intervening gap and said first and second pairs of conductive traces being respectively disposed on said first and second groove sidewalls.
