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