Antenna system and method
A device comprising a metallic conical portion, said conical portion substantially hollow having a vertex end and a base end, a first cylindrical portion disposed annularly about the base end of the conical portion, a metallic second cylindrical portion coupled to the vertex of the conical portion, said cylindrical portion having a threaded aperture, and an antenna feed coupled to the threaded aperture. The device may have a patch disposed on an insulator portion connected to the second cylindrical portion, said patch and insulator portion each having an aperture, and a metallic ground portion connected to the insulator portion, said ground portion having an ground aperture, and a threaded screw disposed through the ground aperture, the patch, the insulator aperture and into the threaded aperture. An RF feed may be created by coupling the threaded aperture to a conductive material disposed on the insulator portion.
