Contactless communication unit connector assemblies with signal directing structures
Contactless extremely high frequency (EHF) signal directing and blocking structures are disclosed herein. The EHF signal directing structures may focus EHF signal energy along a desired EHF signal pathway. The EHF signal blocking structures may minimize signal propagation through substrates such as circuit boards. Focusing EHF signal energy and selectively blocking the EHF signal energy can minimize or eliminate crosstalk and enhance data transmission speed and integrity.
