7461444, Dec 9, 2008

Filed:

Mar 28, 2005

Appl. No.:

11/090598

Inventors:

Michael A. Deaett - North Kingstown RI, US

International Classification:

H01P 11/00

US Classification:

29600, 29601, 343700 MS

Abstract:

Antennas are fabricated using fabric substrates, and, in some embodiments, known stitching techniques to fabricate the conductive members required, including connecting wiring and radiating and/or receiving elements. In one embodiment, one or more “patch antennas”, that is, planar radiating and/or receiving elements, are connected to transmitting and/or receiving electronics by means of a connector and feed line structure. The antenna structure comprises multiple layers of fabric, some of which may contain patch antenna and/or feedline patterns made of conductive fabric, made by embroidery using conductive thread or yarn, or onto which patch antennas may be bonded. A ground plane layer may be fabricated similarly. Between the fabric layers containing the conductive patterns, there are one or more layers of insulating fabrics that separate the conductive fabric layers by a dielectric layer. Additional sheets of adhesive between the fabric layers may be used to attach the fabric layers.

International Classification:

H01P 11/00

US Classification:

29600, 3405721

Abstract:

A method of constructing fabric microwave antennas with a calendering apparatus which comprises: providing a calendaring apparatus having a plurality of roller two of said rollers are arranged as a nip or meeting point; heating said rollers located at said nip; setting the pressure at said nip or meeting point of said rollers; shaping antenna patches from conductive fabric; feeding at least one roll of carrier fabric into said heated and pressurized nip; placing said preformed conductive patches on to the carrier fabric before said carrier fabric enters said heated and pressurized nip of the calendering apparatus so that said preformed conductive patches and said carrier fabric are bonded or calendered by the heat and pressure effects of said nip; and cutting said calendered or bonded layers of conductive and non-conductive fabric into desired shapes for incorporation into flexible structures.

International Classification:

H01Q 1/38

US Classification:

Abstract:

A microwave patch antenna comprising: a plurality of conductive antenna patterns; a plurality of groundplanes; a plurality of feed elements; a plurality of feed slots to allow feed elements to pass through the non-woven dielectric spacers; and a plurality of dielectric separator layers comprised of corrugated non-woven fabric as necessary to form a patch antenna construction.

Inventors:

Michael Deaett - North Kingstown RI, US

International Classification:

H01B 3/44

US Classification:

343897000, 343718000, 17411000R, 428370000, 029600000

Abstract:

This patent describes fabric antenna and fabric microwave circuits and the method for making the same. Microwave conducting material is incorporated into non-woven fabrics using a calendaring process to produce an antenna or microwave circuits. The resulting material can then be manufactured into garments, either as filler material or as a garment itself The carrier fabric of these antennas also allows for said antennas to be flexible and allows for folding for storage. In the current state of the art, antennas are added to a garment during said garment's construction as opposed to incorporation into the fabric itself.

Abstract:

A system and method for imaging target detection includes scanning a target area to produce an image of the target area and discriminating a target by identifying image pixels of similar intensity levels, grouping contiguous pixels with similar intensity levels into regions, calculating a set of features for each region and qualifying regions as possible targets in response to the features; discriminating the background by identifying image pixels of similar intensity levels, grouping contiguous pixels of similar intensity levels into regions, calculating a set of features for each background region and qualifying background regions as terrain characteristics in response to the features and analyzing the qualified terrain characteristics and qualified target candidates to determine and prioritize targets.
