1. An antenna system comprising:

  • a plurality of radiation elements aligned in a common plane and uniformly spaced with respect to each other circumferentially about an axis perpendicular to the common plane extending centrally between the radiating elements; and

    a first reflector centrally located with respect to the radiation elements in a radiation direction of the radiation elements away from the common plane, the first reflector having a conical configuration, the apex of the first reflector being disposed in proximity to the radiating elements and the base of the first reflector being disposed away from the radiation elements, wherein the base of the 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; and

    wherein a center axis of the first reflector extends at an angle to the common plane other than ninety degrees.
