Shielded EHF connector assemblies
Shielded extremely high frequency (EHF) connector assemblies are disclosed herein. In some embodiments, a first extremely high frequency (EHF) shielded connector assembly configured to be coupled with a second EHF shielded connector assembly. The first EHF connector assembly can include a first EHF communication unit operative to contactlessly communicate EHF signals with a second EHF communication unit included in the second EHF shielded connector assembly. The first connector can include a connector interface that includes a configuration to interface with a respective connector interface of the second EHF shield connector assembly, and several different material compositions that, in conjunction with the configuration, provide shielding to prevent or substantially reduce EHF signal leakage when the first EHF assembly connector is coupled to the second EHF assembly connector and the first EHF communication unit is contactlessly communicating EHF signals with the second EHF communication unit.
