1. An electrical connector comprising:a dielectric housing;
a plurality of electrical signal contacts that are carried by the dielectric housing, and that are arranged along a first plane that extends along both a first direction, and a second direction that is perpendicular to the first direction, wherein the electrical signal contacts define respective mating ends, respective mounting ends, and electrical signal pairs;
a ground plate carried by the dielectric housing, the ground plate including a ground plate body oriented in a second plane that is substantially parallel to the first plane and offset from the first plane, the ground plate body defining first and second opposed surfaces, and the ground plate including a plurality of ribs that are contained in the ground plate body and that define first and second opposed surfaces, wherein the first surfaces of the ribs project from the first surface of the ground plate body in a direction toward the first plane, the second surfaces of the plurality of ribs are recessed into the second surface of the ground plate body; and
a plurality of ground mounting ends disposed between mounting ends of adjacent electrical signal pairs, wherein the ground mounting ends are electrically coupled to the ground plate, wherein the plurality of ground mounting ends are disposed in the respective gaps in the first plane aligned with the mounting ends of the electrical signal contacts and offset from the ground plate body,
wherein the electrical signal pairs comprise differential pairs and the plurality of ribs are positioned between respective adjacent differential pairs.
