Claim:
1. A printed circuit board comprising: at least one electrical signal trace elongate along a first direction; an electrically conductive ground layer disposed below the at least one electrical signal trace along a second direction that is perpendicular to the first direction, the electrically conductive ground layer extending along a plane that is normal to the second direction; a first linear array that includes at least one electrically conductive signal via and at least one electrically conductive ground via, the first linear array oriented along the first direction; a second linear array that includes at least one electrically conductive signal via and at least one electrically conductive ground via, the second linear array being oriented along the first direction and being spaced from and consecutive with the first linear array along a third direction that is perpendicular with respect to each of the first and second directions such that no other linear arrays that (i) are oriented along the first direction and (ii) include an electrically conductive signal via are disposed between the first linear array and the second linear array with respect to the third direction; and at least one group of ground isolation vias that is oriented along the first direction, the at least one group of ground isolation vias disposed between the at least one electrical signal trace and the second linear array with respect to the third direction, wherein the at least one electrical signal trace is disposed between the first and second linear arrays with respect to the third direction.
