Patents by Inventor Kaisheng Hu

Kaisheng Hu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240021970
    Abstract: A Printed Circuit Board (PCB) and methods for manufacturing the PCB board are provided. The PCB includes a plurality of layers; a signal pad, at a first layer of the plurality of layers, connected to a signal transmission trace strip line, at a second layer of the plurality of layers, wherein the signal pad is configured to connect to a surface mount Radio Frequency (RF) connector that is configured to interface an RF signal with the signal pad; a PCB ground cage structure through the plurality of layers, surrounding the signal pad; and extended ground reference planes located at the first layer and a third layer of the plurality of layers, wherein the extended ground reference planes extend into a volume of the PCB ground cage structure.

  • Patent number: 11791527
    Abstract: A Printed Circuit Board (PCB) and methods for manufacturing the PCB board are provided. The PCB includes a Radio Frequency (RF) signal transition at a RF signal pad. Multiple conductive layers other than a conductive signal layer of the PCB and conductive portions of the conductive signal layer not in electrical contact with a RF signal transmission trace have common ground connections forming a ground cage structure within the PCB around the RF signal pad and RF the signal transmission trace.
