Abstract
Described are methods and apparatus, including a method of manufacture, for a compact antenna. Two biconical dipole antennas and a monocone monopole antenna are displaced in an adjacent and orthogonal configuration. The two biconical dipole antennas are each shunted to the monocone monopole antenna.
Claims26
A compact antenna, comprising:
- a first biconical dipole antenna;
- a second biconical dipole antenna adjacent to and at least substantially orthogonal to the first biconical antenna;
- a monocone monopole antenna adjacent to and at least substantially orthogonal to the first biconical antenna and the second biconical antenna;
- and
- one or more electrically conductive members that shunt at least one of the first biconical dipole antenna or the second biconical dipole antenna to the monocone monopole antenna.

A method for manufacturing an antenna, the method comprising:
- arranging a first biconical dipole antenna at least substantially orthogonal to a second biconical dipole antenna;
- arranging a monocone monopole antenna at least substantially orthogonal to the first biconical dipole antenna and the second biconical dipole antenna;
- arranging a first antenna feed point for the first biconical dipole antenna adjacent to a second antenna feed point for the second biconical dipole antenna and an axis of rotation of the monocone monopole antenna;
- and
- shunting at least one of the first biconical dipole antenna or the second biconical dipole antenna to the monocone monopole antenna.
2 more elements
A method for transmitting and receiving electromagnetic energy in a compact antenna, the method comprising:
- providing a first biconical dipole antenna, a second biconical dipole antenna and a monocone monopole antenna, each plane disposed adjacent and at least substantially orthogonal relative to one another;
- shunting at least one of each conical element of the first biconical dipole antenna and the second biconical dipole antenna to the monocone monopole antenna;
- and
- providing electromagnetic energy to at least a first feed point for the first biconical dipole antenna, the first feed point adjacent a second feed point for the second biconical dipole antenna and an axis of rotation of the monocone monopole antenna.
