  • Patent number: 8965276
    Abstract: An apparatus includes an antenna for transmitting RF radiation and being structured to enable the distribution of RF energy emitted therefrom to be varied in the vertical plane. The apparatus comprises a generator for generating an RF signal and to pass the signal to the antenna, and a controller arranged to control the distribution of RF energy emitted from the antenna in the vertical plane in response to positional information about an object.
    Type: Grant

  • Patent number: 8400367
    Abstract: An antenna assembly is provided for mounting on a predetermined support structure positioned on a surface, the support structure having a peripheral edge at an elevated position above the surface. The antenna assembly includes an antenna and a support for supporting the antenna at an elevated position above the surface when mounted on the support structure. The support is adapted to support the antenna at a sufficient height above the surface to provide a direct path for electromagnetic radiation at least a portion of the antenna to a position on the surface external of the peripheral edge of less than or equal to about 4.5 meters from substantially any point on the peripheral edge, or to a position on the surface at a point positioned 3 meters from the front of the support structure and 3 meters from a side of the support structure.

  • Patent number: 6215812
    Abstract: A system for canceling contaminating narrowband interference for a wideband DSSS receiver by weighting a channelized copy of the signal of interest in accordance with the result of a correlation between a narrowband copy of the channelized signal of interest centered around the center frequency of the contaminating narrowband interference and a narrowband copy of a wideband feedback signal centered around the center frequency of the contaminating narrowband interference.
