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.
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 disposed substantially annularly about the vertex end;
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 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.
5. The device of claim 4 wherein the aperture is threaded and the fastener is a screw.
6. The device of claim 4 wherein the aperture is not threaded and the fastener is a screw and a nut assembly.
