## Abstract

A device comprising a plurality of metallic conical radiators, said conical radiators 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 patches disposed on a substrate as a one or multi-dimensional array. An RF feed may be coupled to the radiators.

## Claims
