Abstract
An antenna assembly is provided, including a first radiative element. The first radiative element is oriented such that a first end of the radiative element is operatively connected to an antenna feed and at least a portion of the radiative element includes a first conical, helical coil. The first conical, helical coil reaches a maximum diameter at a point farthest from the antenna feed. A counterpoise structure includes one of an electrically conductive ground structure operatively connected to a ground associated with the antenna feed and a second radiative element operatively connected to the antenna feed and the first radiative element at the antenna feed.

An antenna assembly comprising:
- a first radiative element, a first end of the radiative element being operatively connected to an antenna feed, the first radiative element having a height above the connection to the antenna feed between four-hundredths of the characteristic wavelength and one-tenth of the characteristic wavelength and being configured to reach a maximum diameter at a point farthest from the antenna feed;
- and
- a counterpoise structure comprising one of an electrically conductive ground structure operatively connected to a ground associated with the antenna feed and a second radiative element operatively connected to the antenna feed.
An antenna assembly, having a characteristic wavelength associated with an operating frequency of the antenna, comprising:
- a conical, helical radiative element, oriented such that a first end of the radiative element is operatively connected to an antenna feed, at least a portion of the radiative element comprising a conical, helical coil, wherein the conical, helical coil reaches a maximum diameter at a point farthest from the antenna feed;
- and
- a planar ground structure with a diameter less than one-tenth of the characteristic wavelength.
An antenna assembly, having a characteristic wavelength associated with an operating frequency of the antenna, comprising:
