Differential electrical connector with improved skew control

An electrical connector comprising:

• a housing;
• a plurality of conductive elements comprising intermediate portions held within the housing, the plurality of conductive elements comprising at least one pair comprising a first conductive element and a second conductive element, the first conductive element being longer than the second conductive element,
• wherein:
• the housing comprises a first region of a first dielectric constant and a second region of a second dielectric constant and a third region of lossy material;
• the second dielectric constant is lower than the first dielectric constant;
• the second region is positioned with respect to the first conductive element to compensate for skew between the first and second conductive elements;
• and
• the first conductive element comprises an impedance compensation portion along an edge of the first conductive element facing the second conductive element adjacent the second region.
