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.
Claims11
A method including:
- forming a conical radiator having a top cylindrical end and a vertex end, said vertex end including a substantially cylindrical portion extending from the vertex end, said substantially cylindrical portion including a threaded receiver, and
- disposing the cylindrical portion on a dielectric surface at a predetermined height with a fastener disposed through the dielectric surface and into the threaded receiver, wherein the height effectuates a predetermined impedance.
The method of 3 wherein the height of the cylindrical portion and the size of the ground plane operate to direct the radiated energy in a predetermined pattern.
A method including:
- selecting a desired radiation band;
- forming a conical radiator, said radiator having a vertex on one end and base end opposite the vertex, said vertex including a substantially cylindrical, threaded shaft portion;
- disposing the conical radiator on a dielectric substrate with a fastener disposed through the dielectric surface and into the threaded shaft portion;
- coupling RF energy to the conical radiator, said coupling at a characteristic impedance,
- wherein the dimensions of the cone are operable to match impedance and radiate the RF energy in a predetermined pattern.
