Self-supporting antenna

A self-supporting antenna having a maximum lateral dimension in a range from about 15 mm to about 150 mm, and comprising an elongated electrically conductive cut spiral ridge formed from an electrically conductive film disposed directly on and aligned with an adhesive layer, the electrically conductive film having a width (W) in a range from about 100 to about 1000 microns, a height (H) in a range from about 15 microns to about 400 microns, and extending longitudinally along a length and between first and second ends of the conductive cut spiral ridge, such that when the self-supporting antenna is held in air from an edge of the antenna, the thickness of the antenna increases by less than 10 times a planar thickness of the antenna.

An antenna comprising a self-supporting electrically conductive wire having a width (W) and extending longitudinally along a length and between first and second ends of the conductive wire, the conductive wire forming one or more loops and comprising an electrically conductive layer disposed directly on and aligned with an adhesive layer, a width and a length of each of the conductive layer and the adhesive layer being substantially co-extensive with the width and the length of the conductive wire, and a shape of each layer present in the antenna as seen in a plan view being substantially similar to a shape of the conductive wire as seen in a plan view, wherein the adhesive layer comprises an adhesive at least partially embedded in a woven material and comprising a plurality of insulative fibers coated with an electrically conductive material, wherein self-supporting is defined as when the antenna is held in air from the edge of the antenna, a thickness of the antenna increases by less than 10 times a planar thickness of the antenna.
