Abstract

Electrical connector including a plurality of mating conductors. Each of the mating conductors extends between an engagement portion and an interior portion. The engagement portions of the mating conductors are configured to engage contacts of the mating connector. The engagement portions are located proximate to one another at a first nodal region. The interior portions are located proximate to one another at a second nodal region. The electrical connector also includes a first open-ended conductor electrically connected to the engagement portion of a first mating conductor of the plurality of mating conductors and extending from the first nodal region. The electrical connector also includes a second open-ended conductor electrically connected to the interior portion of a second mating conductor of the plurality of mating conductors and extending from the second nodal region. The first open-ended conductor is capacitively coupled to the second open-ended conductor.
