A nanofabric antenna is provided. The nanofabric antenna can include a fabric and a plurality of conductive nanowires extending outwardly from the fabric with the conductive nanowires forming a random array of monopoles. In this manner, an antenna can be included as part of a piece of clothing and/or a piece of fabric used or worn by an individual.

Nanofabric antenna

A radio frequency patch antenna having a radiator patch constructed of an anisotropic material, such as carbon nanotube sheet material. Such material is flexible so that the antenna may be wearable and/or integrated into a textile substrate. A feed line couples the radio signal to the patch. Furthermore, the efficiency of radiation from the patch is directly related to the orientation of the fibers or carbon nanotubes in the anisotropic material relative to the orientation of the feed line. Dual polarized radiators can be constructed from two orthogonal layers of CNT patches fed with correspondingly orthogonal feed lines.

Radio frequency anisotropic patch antenna and polarization selective surface

A method and apparatus for providing multiple functions using nanotube threads comprising: a first nanotube thread and a second nanotube thread, the first nanotube thread and the second nanotube thread arranged to form a mesh, wherein the first nanotube thread further comprises a measurable invariant property and the second nanotube thread comprises a measurable variant property.
