摘要:
A printed circuit board with reduced signal distortion, including one or more layers of non-conductive substrate upon which are disposed conductive pathways that conduct signals, the signals characterized by distortion at least partly caused by orientation of the conductive pathways on the layers of the printed circuit board, and a periodically patterned reference plane; each conductive pathway that conducts signals oriented orthogonally or diagonally at forty-five degrees with respect to other conductive pathways that conduct signals on the printed circuit board; the periodically patterned reference plane comprising a conductor having discontinuities arranged in a periodically recurring pattern, the pattern of the discontinuities oriented on a surface of a layer of the printed circuit board at an optimum angle, with respect to the conductive pathways that conduct signals on the printed circuit board, that reduces distortion of the signals.
