Filed:

Jan 9, 2004

Appl. No.:

10/755033

Inventors:

David J. Holloway - Whittier CA, US
Donald E. Jeckell - Glendora CA, US
Rene F. Gomez - Cerritos CA, US

Assignee:

Comant Industries, Inc. - Fullerton CA

International Classification:

H01Q 21/00

US Classification:

343725, 343708, 343722

Abstract:

An aircraft antenna includes an aerodynamic housing structured for attachment to an outer surface of an aircraft, and the housing contains an electromagnetic radiator and tuned over a first band of frequencies potentially to produce secondary radiations in at least a second band of frequencies, and a suppression filter effective at the frequencies of the secondary radiations.

Assignee:

Comant Industries, Inc. - Fullerton CA

International Classification:

H01Q 1/38
H01Q 1/28

US Classification:

343700MS, 343705, 343872

Abstract:

An aircraft antenna includes an aerodynamic housing structured for attachment to an outer surface of an aircraft, and the housing contains an electromagnetic radiator and tuned over a first band of frequencies to produce a first function, and a second electromagnetic radiator to produce a second function, said radiators being arranged to decouple the first radiator and the second radiator from each other.

Appl. No.:

8/303177

Inventors:

David J. Holloway - Anaheim CA

Assignee:

Comant Industries, Inc. - Santa Fe Springs CA

International Classification:

H01Q 900

US Classification:

343749

Abstract:

A monopole radiating blade antenna comprising a driving, high impedance stub mounted to the face of the blade that functions as part of the radiator as well as part of a shunt path between the blade and the base plate. The shunt path is completed by an air coil inductor connected between the center conductor of the stub and the base plate. One embodiment provides the input connector wire and stub in vertical alignment along the center vertical axis of the blade. Another embodiment arranges the stub to be off-set from the input wire. Some advantages over conventional blade antennas include increased gain at low angles of elevation above the horizon, good impedance match over a wide range of frequencies without using conventional 1/4 wave length stub matching that can introduce dielectric losses, low resistance to ground to bleed off static electricity and lightning, non-loading of the high impedance path at design frequencies, and good accommodation of 5/8 wavelength radiator blade dimensioning.

Appl. No.:

9/356073

Inventors:

David J. Holloway - Anaheim CA

Assignee:

Comant Industries, Inc. - Santa Fe Springs CA

International Classification:

H01Q 138

US Classification:

343795

Abstract:

An antenna array includes two acutely bent dipole antenna elements placed back-to-back on a printed circuit board with integrated micro-strip balun transformers which a Wilkinson divider drives 180 degrees out of phase. In an embodiment, the antenna array sits on a vertical blade support structure to form a T-Top section.
