  • Patent number: 8648759
    Abstract: Provided herein are devices, systems and techniques for establishing a variable height conformal antenna array having a planar backplane. More particularly, positioning of radiating elements can be made insensitive to variable ground height by selecting a suitable radiating element, such as a flared notch and arranging them to have a profile such that their outer extremities are positioned along a conformal, curved shape. Differences in radiator heights can be taken up by the addition of parallel vertical ground planes disposed between the radiating elements and the backplane. Adjacent vertical ground planes effectively form cutoff waveguide sections that naturally isolate the backplane from the radiating elements. The vertical ground planes edges effectively form a virtual curved ground for the radiating elements, following curvature of the array profile. Accordingly, heights of radiating elements are uniform with respect to the virtual ground, while being allowed to vary with respect to the backplane.

  • Publication number: 20110267251
    Abstract: A method and system are disclosed for wide angle multibeam antennas. The method and system involve a multibeam antenna system for generating high performance multiple spot beams. In one or more embodiments, the multibeam antenna system includes an oversized antenna reflector and a plurality of antenna feeds. The oversized antenna reflector has its surface shape optimized from a normal parabolic shape in order to broaden and shape the reflected spot beams to improve antenna performance. In addition, the diameter of the oversized antenna reflector is greater than ((100*?)/?), where ? is the wavelength in inches and ? is the beam to beam spacing in degrees. In some embodiments, the ratio of the focal length of the oversized antenna reflector to the diameter of the oversized antenna reflector (F/D) is greater than 0.7. In at least one embodiment, the system further includes an antenna sub-reflector.
