  • Patent number: 8120537
    Abstract: In accordance with various aspects of the present invention, a method and system for designing an inclined antenna array with a hybrid mechanical-electronic steering system with improved radiation performances at low elevation angles is presented. In an exemplary embodiment, a radiating element structure is attached to a mounting surface and includes a patch antenna and a ground plane. The bottom edge of the patch antenna is farther from the mounting surface than the top edge of the patch antenna. If the radiating element structure is used in an inclined array antenna, then the patch antenna has an uncovered view of a low elevation angle. Furthermore, at least a portion of a patch antenna may be uncovered and have a clear view. A clear view of the low elevation angle results in increased directivity and increased polarization quality due to reduced signal scattering.

  • Publication number: 20090278762
    Abstract: In accordance with various aspects of the present invention, a method and system for an antenna modular sub-array super component is presented. The modular sub-array super component allows for multiple antenna product designs to utilize a common low cost aperture element assembly block, quantities of which may be scaled up or down to suit the physical, performance, and power requirements of a specific antenna system. More specifically, a method and system for connecting various components of an antenna modular sub-array using a bar with leads connector is discussed. The bar with leads may connect antenna subcomponents or subassemblies.
