  • Patent number: 10141623
    Abstract: Embodiments herein describe a high-speed communication channel in a PCB that includes a dielectric waveguide coupled at respective ends to coaxial vias. The dielectric waveguide includes a core and a cladding where the material of the core has a higher dielectric constant than the material of the cladding. Thus, electromagnetic signals propagating in the core are internally reflected at the interface between the core and cladding such that the electromagnetic signals are primary contained in the core. The coaxial vias include a center conductor and an outer conductor (or shield) which extend through one or more layers of the PCB. One of the coaxial vias radiates electromagnetic signals into the dielectric waveguide at a first end of the core while the other coaxial via receives the radiated signals at a second end of the core.
