Abstract
An improved electrical connector is provided by compensating for skew in signal conductors of a differential pair while ensuring a uniform impedance along the differential pair. Skew is equalized by regions of lower dielectric constant preferentially positioned adjacent the longer conductor of each pair. Impedance along the length of the signal conductor is equalized by a compensation portion in the first conductor that offsets for a change in impedance associated with the change in dielectric constant adjacent the longer conductor. The compensation portion may be a widening in the first conductive element relative to a nominal width of the conductive element. The skew compensation portion may be along a longer edge of the longer conductor and the impedance compensation portion may be along the shorter edge of the longer conductor.
