US Patent:
8525616, Sep 3, 2013
Filed:
Apr 12, 2010
Appl. No.:
12/758429
Inventors:
Robert K. Shaw - Willow Grove PA, US
Jonathan P. MacGahan - Ivyland PA, US
Sulinder S. Dhanjal - Pennington NJ, US
Erik Lier - Newtown PA, US

Assignee:
Lockheed Martin Corporation - Bethesda MA
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.
Optimized Receive Antenna And System For Precision Gps-At-Geo Navigation
US Patent:
7489271, Feb 10, 2009
Filed:
Jan 29, 2007
Appl. No.:
11/699714

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.
