US Patent:

6859188, Feb 22, 2005

Filed:

Mar 27, 2003

Appl. No.:

10/402085

Inventors:

James W. Matthews - Jamison PA, US
Edwin Thomas Park - Levittown PA, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

H01Q013/00

US Classification:

343781P, 343882

Abstract:

An antenna system particularly suitable for use with a satellite in a terrestrial communication system includes first and second signal reflectors which are selectively positionable with respect to an RF signal feed whereby first and second target areas can be serviced. A support structure is provided for the reflectors whereby the first and second reflectors are rotated into operating positions with respect the RF signal feed. The support structure further includes a hinge for supporting the first reflector whereby the reflector can be rotated between an operating position and a stow position. The support structure further includes a second gimbal which allows the second reflector to independently rotate to a flipped position and then pivot to the stow position adjacent to the first reflector with the concave surfaces of the two reflectors in a stacked position.

Filed:

Jan 29, 2007

Appl. No.:

11/699714

Inventors:

Bernard F. Lindinger - Elkins Park PA, US
James W. Matthews - Doylestown PA, US
Neil E. Goodzeit - Princeton NJ, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

G01S 1/00
H01Q 1/36

US Classification:

34235706, 343895

Abstract:

A GPS-at-GEO system is provided that includes a receive antenna design that enables improved tracking of GPS space vehicle side-lobe signals. The receive antenna design is a conical mode helix antenna configured to produce a conical mode radiation pattern, which has zero gain at Nadir and higher gain in the side-lobe signal regions. The conical mode radiation pattern provides several advantages for GPS-at-GEO navigation applications. For example, this mode provides higher gain in the GPS space vehicle side-lobe signal regions for improved acquisition and tracking performance and lower gain at Nadir, providing reduced noise temperature and higher signal to noise ratio.

International Classification:

H01P 5/12

US Classification:

333135, 333126, 333129

Abstract:

An antenna feed network includes a septum polarizer including a waveguide defining a cavity, wherein a septum is disposed in the cavity to divide the cavity to form a first port and as second port, a diplexer in signal communication with at least one of the first port and the second port of the septum polarizer to route a signal based upon a frequency, and a wave coupler/splitter in signal communication with the diplexer to send and receive signals therebetween, the wave coupler/splitter including a first signal path and a second signal path, wherein the wave coupler/splitter controls a phase shift of a signal transmitted through at least one of the first signal path and the second signal path.

Filed:

Oct 29, 2003

Appl. No.:

10/696093

Inventors:

James Matthews - Berwyn PA, US
Henry Tronco - Springfield PA, US

International Classification:

B05D003/02
B05D001/36

US Classification:

427/407100, 427/385500

Abstract:

The present invention relates to a process for producing a multi-coat system on various substrates, particularly automotive bodies. A crosslinkable component of the composition includes an acid functional acrylic copolymer polymerized from a monomer mixture comprising 2 percent to 12 percent of one or more carboxylic acid group containing monomers, percentages based on total weight of the acid functional acrylic copolymer, and 0.2 percent to 2 percent of amorphous silica, percentages based on total weight of the crosslinkable component. The crosslinking component can includes polyisocyanates, melamines, or a combination thereof.
