Electrical connector and ground structure configured to reduce electrical resonance

Electrical connector includes a connector housing. The electrical connector also includes a plurality of signal conductors coupled to the connector housing. Each of the signal conductors has a first terminal, a second terminal, and an elongated conductor body extending between the first and second terminals. The first terminals are configured to engage corresponding conductive elements of an electrical component. The electrical connector also includes a ground structure coupled to the connector housing. The ground structure is positioned between adjacent signal conductors and has an exterior surface. At least a portion the exterior surface has a textured area that is configured to dampen reflected energy that propagates there along.
