Abstract
A nanotube based microstrip antenna element is provided along with arrays of same. The nanotube based microstrip antenna element comprises a dielectric substrate layer sandwiched between a ground plane layer and a conductive nanotube layer, the conductive nanotube layer shaped to form a radiating structure. In more advanced embodiments, the nanotube based microstrip antenna element further includes an integrated two terminal nanotube switch device such as to provide a selectability function to such microstrip antenna elements and reconfigurable arrays of same. Anisotropic nanotube fabric layers are also used to provide substantially transparent microstrip antenna structures which can be deposited over display screens and the like.
