Abstract

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.

Claims

1. 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;

an antenna feed coupled to the second cylindrical portion;

a patch connected to the second cylindrical portion, said patch disposed on an insulator portion, said patch and insulator portion each having apertures;

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 insulator aperture and the patch aperture and into the second cylindrical portion.

2. The device of claim 1 further wherein the antenna feed is coupled to the second cylindrical portion through the patch.

3. The device of claim 1 wherein the diameter of the base end is approximately either 5 centimeters or 2.4 centimeters.

4. The device of claim 1 wherein the second cylindrical portion has an aperture for receiving a fastener.

7. A device comprising:

a metallic ground portion, said ground portion having a plurality of ground apertures;

at least one insulator portion disposed on the ground portion;

a plurality of patches disposed on the insulator portion;

a conical radiator connected to each patch, and

a feed connector electrically coupled to each conical radiator.

8. The device of claim 7 wherein the feed connector is a metal adhered to each insulator portion.

9. The device of claim 7 wherein the radiators are spaced apart a distance of approximately either 8.75 centimeters or 4.2 centimeters.
