Abstract: A number of board-to-board array connectors are described. An example connector includes a receptacle assembly and a plug assembly. The receptacle assembly includes a receptacle housing and a receptacle interface assembly. The plug assembly includes a plug housing and a plug interface assembly. The plug interface assembly includes a plug contact blade having a cantilevered blade beam. The cantilevered blade beam can be centrally positioned within the plug contact blade in one example. The cantilevered blade beam can be cantilevered toward a contact blade end of the cantilevered blade beam and extends toward a mount end of the cantilevered blade beam. The receptacle interface assembly includes a receptacle contact having a pair of contact beams. The cantilevered blade beam is configured to bend as the pair of contact beams electrically contact and slide along surfaces of the cantilevered blade beam.

Abstract: Antenna elements with orientation angles from zero to ninety degrees from vertical are provided. A housing is provided to support the antenna elements. Among other features, each antenna element can include dielectric fillers to control electromagnetic coupling. The housing supporting the antenna assemblies can be saucer shaped and provides a ground reference.

Abstract: Systems for connecting RF coaxial cables are disclosed. In some embodiments, the systems include the following: a plug including a D-sub housing having two rows of eight RF coaxial contacts and a plurality of protrusions extending therefrom; a receptacle including a D-sub housing having two rows of eight openings and a plurality of indentations that are sized and positioned so as to mate with the protrusions extending from the plug, the receptacle including a rear unibody joined with the D-sub housing and a transition body positioned between and joining the D-sub housing and the rear unibody. The plug and receptacle are configured to provide about a 50-Ohm impedance across the system and the plug and receptacle are configured to operate under a ground-first condition.
