US Patent:

8254851, Aug 28, 2012
Filed:

Nov 11, 2008
Appl. No.:

12/268840
Inventors:

Dave Laidig - Mesa AZ, US
Kenneth V. Buer - Gilbert AZ, US
Friedhelm Wachter - Phoenix AZ, US
Assignee:

ViaSat, Inc. - Carlsbad CA
International Classification:

H04B 1/38
US Classification:

455 903, 333135
Abstract:

A method and system for an integrated transceiver is presented. The integrated transceiver includes a transceiver housing, where a waveguide is formed inside the transceiver housing using a housing base and a sub-floor component. Neither the housing base nor the sub-floor component alone is configured to operate as a waveguide. In an exemplary embodiment, a portion of the waveguide is cast into the housing base and is part of the transceiver housing. Furthermore, in an exemplary embodiment, an antenna system includes a feed horn, a polarizer, the integrated transceiver, and a transceiver circuit that communicates with the waveguide to transmit and receive radio frequency signals. The integrated transceiver, in the exemplary embodiment, includes a transceiver housing base that forms a portion of an integrated waveguide assembly, and another portion of the integrated waveguide assembly aligns with the transceiver housing base to form the integrated waveguide assembly.

Abstract:

A method and system for an integrated transceiver is presented. The integrated transceiver includes a transceiver housing, where a waveguide is formed inside the transceiver housing using a transceiver housing and a sub-floor component. Neither transceiver housing nor the sub-floor component alone is configured to operate as a waveguide. The integrated transceiver can include a transceiver housing that forms a portion of an integrated waveguide assembly, where the transceiver housing alone does not form the waveguide, and another portion of the integrated waveguide assembly couples with the transceiver housing to form the waveguide of the integrated waveguide assembly. Further, the integrated waveguide portion of the sub-floor component can be a flat surface, where the integrated waveguide portion of the transceiver housing comprises substantially all the features of said integrated waveguide.

Filed:

Apr 13, 2010
Appl. No.:

12/758966
Inventors:

David W. Corman - Gilbert AZ, US
Friedhelm Wachter - Phoenix AZ, US
Kenneth V. Buer - Gilbert AZ, US
Assignee:

VIASAT, INC. - Carlsbad CA
International Classification:

H01Q 3/00
H01Q 3/12
H04B 7/185
US Classification:

342354, 343761, 342372
Abstract:

This disclosure may relate generally to systems, devices, and methods for a phased array illuminated reflector dish RF antenna combining a phased array with a microwave reflector dish and using beam steering to align the antenna beam to maximize antenna performance. The phased array may be connected in communication with one of a transmitter, a receiver, and a transceiver. In various exemplary embodiments the phased array illuminated reflector dish RF antenna includes a boom arm supporting the microwave reflector dish and the phased array. In one exemplary embodiment, the phased array only communicates signals with a remote source of the signals via the microwave reflector dish (not directly). The RF antenna system may be configured to be rough pointed by mechanically aiming the RF antenna system, and the RF antenna system is configured to fine tune aim the beam of said RF antenna system by beam steering.
