Abstract
A circuit board is provided for improving signal quality, including a signal plane for a plurality of signal traces arranged thereon and a ground plane formed by a plurality of tiles connected to each other in an array. Each tile is formed by ground traces. Different line segments of a signal trace mapped on the ground plane cross ground traces of the tiles at similar angles, thereby minimizing interaction between the ground traces and the signal traces to reduce differences in impedances of the signal traces.
