摘要： Methods and apparatuses for vertically transitioning signals between substrate integrated waveguides within a multilayered printed circuit board (PCB) are disclosed. A first substrate integrated waveguide (SIW) is provided in a first layer of the PCB, the first SIW having a first terminal portion. A second SIW is provided in a second layer of the PCB, the second SIW having a second terminal portion that overlaps with the first terminal portion, wherein a first ground plane separates the first SIW and the second SIW. A vertical transition comprising an aperture in the first ground plane that is disposed in an area defined by the overlap of the first terminal portion and the second terminal portion, such that a signal propagated in the first SIW transitions to the second SIW in a different layer through the aperture.

摘要： Embodiments herein describe a high-speed communication channel in a PCB that includes a dielectric waveguide sandwiched between two ground layers. 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.

摘要： 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.

摘要： A printed circuit board (‘PCB’) including a substrate integrated waveguide (‘SIW’) formed using two ground planes representing the top and bottom walls of the waveguide, tightly pitched ground vias to act as two side walls and two back walls, and a pair of monopole antennas placed at each end of the SIW acting as signal feeding/receiving structures is disclosed. The waveguide dominant mode cut off frequency is determined by the spacing between the two side walls. Within each monopole antenna pair, the first monopole antenna operates at a first frequency while the second monopole antenna operates at another frequency. For each monopole antenna pair, the first monopole antenna and the second monopole antenna are located in the SIW at a distance from the back wall optimal for each operating frequency.
