Transition between a laminated PCB and a waveguide including a lamina with a printed conductive surface functioning as a waveguide-backshort
Abstract:
A system for directing electromagnetic millimeter-waves towards a waveguide using an electrically conductive formation within a Printed Circuit Board (PCB). The system includes a waveguide having an aperture and at least two laminas belonging to a PCB. A first electrically conductive surface printed on one of the laminas is located over the aperture such that the first electrically conductive surface covers at least most of the aperture. A plurality of Vertical Interconnect Access (VIA) holes, optionally filled or plated with an electrically conductive material, are electrically connecting the first electrically conductive surface to the waveguide, forming an electrically conductive cage over the aperture. Optionally, a probe printed on one of the laminas of the PCB is located inside the cage and over the aperture.
