Abstract:
An antenna having an elongated housing open at one end and defining an interior chamber. A telescoping mast has a carrier attached at a first end and a flexible antenna attached at its other end. The carrier with the attached mast and antenna is movable between a storage position in which the carrier, mast, and antenna are contained within the interior chamber of the housing, and a deployed position in which the mast and attached antenna protrude outwardly from the housing. A spring is positioned between the carrier and the housing which urges the carrier towards its deployed position. A catch mechanism selectively holds the carrier in its stored position and, when released, releases the spring to move the antenna to its deployed position.
Abstract:
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.
Abstract:
A planar antenna comprising: a substrate, a resonant element generating an electromagnetic wave, a plurality of parallel, spaced apart conductive strips on the substrate, wherein conductive strips form collinear rows of at least two strips that are physically separated by a slot to guide the electromagnetic wave in a specific direction.
Abstract:
An electromagnetic bandgap structure comprising a progressive cascade of a plurality of patterns of cells. The cells of each pattern are dimensioned so that each pattern has a reflection phase response centered at a different, but closely-spaced, frequency compared with the reflection phase response of an adjacently positioned pattern, so that the combined reflection phase response of the plurality of patterns provides a continuous wideband operational range.
Abstract:
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.
