Title: The Innovations of Francis Marion
Introduction
Francis Marion is a notable inventor based in Gatineau, Canada. He has made significant contributions to the field of electrical engineering, particularly in the development of advanced coaxial-to-printed circuit board (PCB) interfaces and antenna systems. With a total of four patents to his name, Marion continues to push the boundaries of innovation in his industry.
Latest Patents
One of Marion's latest patents is titled "Low PIM coax to PCB interface and method of constructing the same." This invention focuses on creating a low passive intermodulation (PIM) coaxial-to-PCB interface. The method involves coupling signals between an electrical conductor trace in the PCB and an inner conductor of a coaxial structure. A metallic cylinder is used to position the coaxial structure with respect to the PCB, ensuring that the outer conductor and insulator lie below the lower surface of the PCB. The inner conductor is then inserted into a via extending from the lower to the upper surface of the PCB, with solder deposited in the via to establish an electrically conductive path.
Another significant patent is the "Hybrid remote electrical tilt (HRET)." This invention describes a method and antenna system for achieving remote electrical tilt through a combination of analog and digital phase shifting. The HRET antenna system includes a digital beamformer that applies a set of phase shifts to each antenna subarray, suppressing sidelobes when the beam is steered to an elevation. Additionally, an analog phase shifter is employed to further refine the phase shifts, ensuring optimal performance of the antenna system.
