Abstract
A circuit board comprises a plurality of layers, first and second reference conductive vias extending in a vertical direction through at least a portion of the plurality of layers, first and second signal conductive vias extending in the vertical direction between and spaced apart in a horizontal direction from the first and second reference conductive vias through at least a portion of the plurality of layers, and a dielectric region extending in the vertical direction between the first and second signal conductive vias. An air via extends in the vertical direction through the dielectric region between the first and second signal conductive vias. An anti-pad extends in the horizontal direction between the first and second reference conductive vias and surrounding in the horizontal direction the first and second signal conductive vias, the air via, and the dielectric region.
