Patents by Inventor Gordon Evert

Gordon Evert 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 efficiency test device
    Patent number: 7109932
    Abstract: The present invention provides, an antenna test device to test antenna efficiency. The test device includes a cavity formed by at least one conductive sidewall. The cavity contains at least one tuning probe, at least one movable portion, or a combination thereof. The tuning probes and/or movable portion help inhibit the antenna under test from having faulty measurements due to anti resonance or coupling.
    Type: Grant
    Filed: June 18, 2004
    Date of Patent: September 19, 2006
    Assignee: Centurion Wireless Technologies, Inc.
    Inventors: Govind R. Kadambi, Ram M. Narayanan, Yeqin Huang, Gordon Evert, James Blake Winter
  • Method and apparatus to control an antenna efficiency test device
    Patent number: 7109931
    Abstract: The present invention provides a method to measure antenna efficiency using the cavity method. In particular, the present invention provides a tunable cavity that can be tuned to avoid the anti resonance and antenna-cavity coupling problems. In particular, tuning probes and/or variable volumetric sizing of the cavity are used to tune the cavity to avoid the anti resonance and antenna-cavity coupling.
