1. An antenna system comprising:

  • a plurality of radiation elements aligned in a common plane and uniformly spaced with respect to each other semi-circumferentially about an axis perpendicular to the common plane extending centrally through a diameter line of a semi-circle formed on the common plane by the radiating elements; and

    a first reflector located centrally with respect to the diameter line of the semi-circle formed on the common plane by the radiation elements and extending away from the common plane, the first reflector having an inverted, truncated, semi-circular conical configuration, a first base of the first reflector spaced apart from and disposed in proximity to the radiating elements and a second base of the first reflector being disposed away from the radiation elements, wherein the second base of the first reflector has a diameter that exceeds a footprint of the radiating elements and the first reflector reflects the electromagnetic radiation emitted by the radiation elements along the axis and through the common plane to provide a coverage area that extends along the axis beyond the antenna system.
