A circuit board includes a plurality of signal conductors (60, 62, 64) and a grid (20). The grid (20) has a pattern of conductive material which forms cell structures oriented along a first axis (Y). The grid pattern is configured so that when the signal conductors (60, 62, 64) are oriented parallel to the first axis (Y), they overlay a substantially constant area of the conductive material regardless of where the signal conductors (60, 62, 64) are positioned. The capacitance of the signal conductors (60, 62, 64) is thereby controlled so that the impedances of the signal conductors (60, 62, 64) can be maintained at a high level. |
