A
broadband omni-directional
bicone antenna. The antenna can comprise conductive surfaces of conical voids provided within a
solid dielectric structure. The outside surface of the
solid structure can support a
radio frequency (RF) lens geometry operable for beam forming. The beam forming can modify the elevation pattern of the
electromagnetic radiation from the
bicone antenna. The
solid dielectric structure may be machined or molded from a single piece of material. The conical voids provided within the
solid structure can be metallized to provide conductive
bicone radiators. The outer surface
beam shaping lenses can be zoned or continuous and can provide elevation patterns with increased
gain, cosecant squared falloff, or various other patterns. The
beam shaping lens may be formed from any low-loss
dielectric. Alternatively, the lens may be formed from a less
dense material such as dielectric foam that can support radial conductive beam forming vanes.
