Patents by Inventor Kerry Lane Greer

Kerry Lane Greer 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).

  • Integrated front end antenna
    Patent number: 7084823
    Abstract: A radio frequency transmitting and receiving apparatus comprising a filter and an antenna, wherein the input reactance of the antenna is substantially equal in magnitude and opposite in sign to the output reactance of the filter. This reactance relationship permits the antenna and filter to be collocated and avoids transformation of the input and output impedances to the conventional 50 ohms such that the filter and antenna can be connected with a conventional 50 ohm transmission line.
    Type: Grant
    Filed: February 26, 2004
    Date of Patent: August 1, 2006
    Assignee: SkyCross, Inc.
    Inventors: Frank M. Caimi, John Charles Farrar, Kerry Lane Greer, Michael H. Thursby, Donald A. Innis
  • Dual band spiral-shaped antenna
    Patent number: 6856286
    Abstract: A planar antenna comprising a spiral conductive surface comprising an inner spiral segment and an outer spiral segment. A shorting leg for connection to a ground plane and a feed leg responsive to the antenna signal (in the transmit and the receive modes) extend downwardly from the plane of the spiral segments. Performance characteristics of the antenna are responsive to the configuration and spacing of the spiral segments and the distance between the antenna and the ground plane.
