1. An electrical connector comprising:
an electrically insulative connector housing;
a plurality of electrical contacts supported by the connector housing, wherein the electrical contacts are arranged along a plurality of rows; and
an electrical shield configured to reduce near-end crosstalk, the electrical shield including an ungrounded electrically conducive substrate supported by the connector housing between adjacent ones of the rows, wherein the electrical shield further comprises a lossy material,
wherein 1) the electrically conductive substrate defines i) a first side that faces a first row of the adjacent ones of the rows, ii) a second side that is opposite the first side and faces a second row of the adjacent ones of the rows, and iii) at least one edge that extends from the first side to the second side, and 2) the electrical shield further comprises the lossy material disposed on at least one of the first side, the second side, and the at least one edge.
