Multi-Band Antenna Feed With Switchably Shared I/O Port

US Patent:
5635944, Jun 3, 1997
Filed:
Dec 15, 1994
Appl. No.:
8/357904
Inventors:
Harry M. Weinstein - Franklin MA
Joseph M. Baird - Sandy UT
Bryant F. Anderson - Sandy UT
Assignee:
Unisys Corporation - Blue Bell PA
International Classification:
H01Q 1300, H01P 1213
US Classification:
343776
Abstract:
A single integrated antenna feed transmits and receives electromagnetic waves in the C, X, and Ku frequency bands. This antenna feed includes an inner metal tube which lies along a central axis, and an outer metal tube which surrounds and is coaxial with the inner metal tube. Through the inner tube, a passageway is provided which is sized to carry electromagnetic waves in the X-band and Ku-band, but reject electromagnetic waves in the C-band. Between the inner tube and the outer tube, another passageway is provided which is sized to carry electromagnetic waves in the C-band. An I/O port for the X and Ku-bands is provided by a first end of the inner tube, and an I/O port for the C-band is provided by a corresponding first end of the outer tube. This first end of the outer tube lies proximate to but not past the first end of the inner tube. A solid dielectric is inserted into and fills the first end of the inner tube; and, a hollow metal cone is attached to the first end of the outer tube.

Dual Frequency Waveguide Switch

US Patent:
5583469, Dec 10, 1996
Filed:
Dec 15, 1994
Appl. No.:
8/357903
Inventors:
Harry M. Weinstein - Franklin MA
Joseph M. Baird - Sandy UT
Bryant F. Anderson - Sandy UT
Assignee:
Unisys Corporation - Blue Bell PA
International Classification:
H01P 112
US Classification:
333106
Abstract:
A dual frequency waveguide switch passes electromagnetic waves in the X-band along one route, and passes electromagnetic waves in the Ku-band along a different route. This switch includes a housing which has first, second, and third openings for the electromagnetic waves to pass through; and a movable member, mounted in the housing, having first and second passageways. The first passageway is shaped to pass electromagnetic waves in both the X-band and the Ku-band, and the second passageway is shaped to pass electromagnetic waves in the Ku-band but reject electromagnetic waves in the X-band. A forcing mechanism forces the moveable member to a position "A" in the housing where the first passageway interconnects the first opening to the second opening, and to a position "B" where the second passageway interconnects the first opening to the third opening.
