Patents by Inventor Qizhang Hong

Qizhang Hong 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).

  • Antenna and communications apparatus
    Patent number: 11784417
    Abstract: An antenna and a communications apparatus, where the antenna includes surface radiating patches, inner radiating patches, a first dielectric substrate disposed between the surface radiating patches and the inner radiating patches, and a second dielectric substrate disposed below the inner radiating patches and configured to carry antenna feeders coupled to the inner radiating patches. A dielectric constant or dielectric loss of the first dielectric substrate is lower than that of an organic resin substrate, and a coefficient of thermal expansion of the second dielectric substrate is lower than that of the organic resin substrate.
    Type: Grant
    Filed: March 16, 2022
    Date of Patent: October 10, 2023
    Assignee: HUAWEI TECHNOLOGIES CO., LTD.
    Inventors: Ming Chang, Liangsheng Liu, Qizhang Hong
