7030600, Apr 18, 2006
Filed:

Nov 4, 2003
Appl. No.:

10/701044
Inventors:

Michael G. Adlerstein - Wellesley MA, US
Katherine J. Herrick - Westford MA, US
Assignee:

Raytheon Company - Waltham MA
International Classification:

G01S 3/02
US Classification:

324 7614, 324725
Abstract:

A circuit for sensing radio frequency energy. The circuit includes a Wheatstone bridge having at least one element thereof thermally responsive to the radio frequency energy passing therethough differently from radio frequency energy passing though at least one other element of the bridge.

US Patent:

7098854, Aug 29, 2006
Filed:

Sep 9, 2004
Appl. No.:

10/936944
Inventors:

Katherine J. Herrick - Chelmsford MA, US
Assignee:

Raytheon Company - Waltham MA
International Classification:

H01Q 1/38
US Classification:

343700MS, 343845
Abstract:

A reflect antenna element having a receive antenna section and a transmit antenna section. Each section has a cavity, a conductive element in registration with the cavity, and a ground plane conductor having a slot. A strip conductor has portions thereof disposed over the slots and the ground planes conductor. The strip conductor and underlying ground plane conductor form a microstrip transmission line for coupling energy received by the receive antenna section to the transmit antenna section. The transmit antenna section and receive antenna section are configured to operate with orthogonal polarizations. An amplifier is disposed in circuit with the transmission line.

US Patent:

7670045, Mar 2, 2010
Filed:

Jun 18, 2004
Appl. No.:

10/871995
Inventors:

Katherine J. Herrick - Chelmsford MA, US
John P. Bettencourt - Danvers MA, US
Alan J. Bielunis - Hampstead NH, US
Assignee:

Raytheon Company - Waltham MA
International Classification:

G01K 17/02
G01K 7/00
G01J 5/00
US Classification:

374 32, 374179, 374122, 136225
Abstract:

A power sensor having a microstrip transmission line, comprising: a dielectric substrate; a strip conductor disposed on one surface of the substrate; and a ground plane conductor disposed on an opposite surface of the substrate. The power sensor includes a plurality of thermocouples extending from the strip conductor, proximal end portions of the thermocouples being thermally coupled to the strip conductor. A plurality of electrical conductors is provided, each one having a first end electrically connected to a distal end of a corresponding one of the thermocouples and a second end electrically connected to the proximate end of one of the plurality of thermocouples disposed adjacent to such corresponding one of the thermocouples. The proximal ends of the thermocouples are electrically insulated one from the other.
