  • Patent number: 8253638
    Abstract: An easily transportable multiband antenna array. The antenna array is fabricated on a multi-sided structure, such as a four-sided cube, made from a wire frame and fabric. The multi-sided structure is constructed so that it may be folded by first folding the faces against each other, and then twisting them to form a stack of loops. The antenna elements are fabricated on the faces, and comprise at least a loop antenna around the perimeter of each face, and a bow-tie antenna attached to each face. The antenna elements are fabricated and attached so that they do not inhibit the folding of the structure.
    Type: Grant

  • Patent number: 6249261
    Abstract: A direction-finding antenna constructed from polymer composite materials which are electrically conductive is shown with the polymer composite materials replacing traditional metal materials. An inherent advantage of replacing metal materials is significantly lower radar reflectivity (radar cross section) and lower weight. The reduced radar reflectivity reduces the range of detectability of the antenna by possible adversaries. Despite significantly lower radar reflectivity, the antenna assembly has direction-finding characteristics which are essentially equivalent to traditional metal antennas.
