    • 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.
    • 具有降低的信号失真的印刷电路板,包括一层或多层不导电基底,在其上设置传导信号的导电路径,其特征在于至少部分地由印刷的层上的导电路径的取向引起的变形 电路板和周期性图案化参考平面; 每个导电通路相对于在印刷电路板上传导信号的其它导电通路传导正交或对角地定向四十五度的信号; 所述周期性图案化参考平面包括具有以周期性重复图案布置的不连续性的导体,所述不连续性的图案相对于在所述印刷电路板上传导信号的导电路径以最佳角度定向在所述印刷电路板的层的表面上 印刷电路板,可以减少信号的失真。
