  • Patent number: 8174457
    Abstract: A broadband antenna apparatus that is generally disposed along a plane. The antenna apparatus includes a ground plate with an edge and an inverted “L” antenna that has a base leg and an elongated leg, which define an interior corner. The interior corner is filled with a triangulated portion for broadening the bandwidth of the antenna. There is an antenna feed point at a distal end of the base leg. The antenna is oriented so that the distal end of the base leg is adjacent to the edge, forming a first dielectric gap therebetween, and further oriented with the elongated leg parallel to the edge. A first parasitic ground element extends from the edge and is positioned adjacent to the base leg, forming a second dielectric gap therebetween. The antenna apparatus also includes a second parasitic ground element extending from the edge of the ground plate.

  • Patent number: 8120543
    Abstract: A transmission line slot antenna is described. Although more generally applicable, the antenna is particularly adapted to conformal applications. The antenna has a ground plate with a conductive top surface having a slot with a feed whose ground reference terminal is connected to one side of the slot and whose signal terminal is connected to the other side of the slot. A conductive cylindrical screen, which can be of an arbitrary cross section and non-uniform in the longitudinal direction, is formed of one or more sections attached along the bottom surface of the ground plate, with each of the sections having a first and second edge conductively connected to the top surface of the ground plate along opposite sides of the slot. The antenna is tuned to support the fundamental mode (H00) of a slotted cylinder transmission line formed by the screen sections and a part of the ground plate with the slot.
