Assignee:

Raytheon Company - Waltham MA

International Classification:

H01Q 13/00

US Classification:

343786, 343785

Abstract:

Methods and apparatus for a feed assembly for a reflector antenna including an aperture common to low, mid, and high frequency bands, a polyrod design to launch signals in the mid and high frequency bands, a horn to launch signals in the low frequency band, a co-located phase center for launching signals in the low, mid, and high frequency bands, and a low-band monopulse array located on a surface about the aperture to track a satellite.

International Classification:

G06Q 30/00

US Classification:

705 1449, 705 263

Abstract:

The present disclosure is directed to systems and methods for providing an opaque online marketplace and distribution network for items, tickets, tokens, and other goods or services using a dynamic pricing engine and user-specific market price adjustments, and drawing inventory from multiple sources. Under-sold inventory from an inventory source may be monetized, while protecting the brand of the market entities, and consumers may be allowed to purchase items and tickets at a dynamic market value which, in some cases, may be below face value or a default retail price. Furthermore, a market price may be adjusted by a user-specific price adjustment, on an individualized basis, to manage user satisfaction and provide incentives.

- Waltham MA, US
Larry C. Martin - Los Angeles CA, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

H01Q 1/42
H01Q 1/48
H01Q 15/00

Abstract:

An armored radome includes an electrically-conductive ground plane that provides load bearing and/or ballistic protection to a shielded sensor, and a pair of radiator structures on opposing surfaces of the ground plane. The radiator structures each include an antenna, and the ground plane includes one or more coaxial feedthroughs that couple the antennas for reradiation of signals. One or both of the radiator structures may include a frequency-selective surface (FSS) according to a desired operating frequency range or to shape a frequency response of the radome. The disclosed radome is both mechanically strong, and electromagnetically transparent, or nearly so, across a wide range of frequencies and transmit/receive angles.

International Classification:

H01Q 21/06

H01Q 1/48

Abstract:

A wideband dual-polarized current loop antenna element is provided having a ground tower and an antenna circuit integrated, such as within a multi-layer circuit board configuration. The antenna circuit includes feed conductors and element conductors, each of which are capacitively coupled to a top ground plane of the ground tower. The feed conductors are coupled to receive signals from coaxial feed lines coupled to the respective antenna element and element conductors are coupled to receive signals from adjacent antenna elements, such as in an antenna array configuration. The antenna element can further include one or more frequency selective surface (FSS) layers disposed proximate to the top ground plane of the ground tower and the antenna circuit. The ground tower, antenna circuit and one or more FSS layers can be formed to provide a low-profile antenna element having wide broadband performance.
