Patents by Inventor David Glen Landon

David Glen Landon 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).

  • Patent number: 8279122
    Abstract: A wireless communication system can include polarization agile antennas to enable adaptation to the polarization characteristics of a changing propagation channel. In one embodiment, a mobile terminal can include one or more polarization-agile antennas, and can select polarization orientations that are preferentially propagated through the changing propagation channel. In another embodiment, a mobile terminal having two polarization-agile antennas can provide spatial diversity, polarization diversity, or combinations of both. Multiple-input multiple-output (MIMO) systems can include polarization-agile antennas to allow for switching between spatial and polarization diversity, combined spatial and polarization diversity, and various Eigen channel decompositions using spatial, polarization, and combined spatial and polarization dimensions. An extended polar normalization provides enhanced fidelity for methods of communications system modeling.
