Abstract: An Antenna comprising a ground layer, a feed layer, an antennal layer and a corrugated or dimpled non-woven fabric dielectric substrate interposed between two of the layers. The use of said non-woven corrugated fabric is to provide differing distances between the ground layer and the antenna layer as well as to provide both light weight construction and flexibility.

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: 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.
