An electromagnetic reflector composed of a non-knitted, non-metallic carbon-based material mesh, antenna system incorporating the reflector and method for fabrication are disclosed.

Laser cut carbon-based reflector and antenna system

A reflector antenna, preferably a fixed mesh reflector antenna, and a process for manufacturing the reflector antenna, is disclosed that includes forming a support structure, placing a reflector surface on a mold, attaching the support structure to the reflector surface, measuring the geometry of the reflector surface, adjusting the surface geometry of the reflector if appropriate to obtain improved accuracy for the reflector surface, and fixedly connecting the support structure and the reflector surface. In an embodiment, the antenna reflector system includes a mesh reflector surface, a plurality of spline support elements, a plurality of splines connected to the reflector surface, and a plurality of adjustable spline supports attachable to the spline support elements and the splines, wherein the adjustable spline supports are adjustably repositionable with respect to the spline support elements, and also fixedly connectable to the spline support elements.

High operational frequency fixed mesh antenna reflector

An antenna reflector comprising a mesh material formed of a Carbon Nano-Tube ('CNT') yarn that is reflective of radio waves and has a low solar absorptivity to hemispherical emissivity ratio (&#x3b1;/&#x3b5;ratio) and a low Coefficient of Thermal Expansion ('CTE').

The invention concerns a reflector () of radio frequency (RF) energy. The reflector includes a first web layer () formed from a knit of at least a first conductive filament (), and a second web layer () formed of a knit of at least a second conductive filament (). The first and second web layers can be formed as an open mesh. The second web layer is positioned on the first web layer to form a stack. Fastening members () are disposed at intervals across a surface of each of the first and second web layers. The fastening members are advantageously configured to secure the first web layer to the second web layer. The invention also concerns a reflector antenna formed using the reflector of radio frequency energy. The reflector antenna includes antenna support elements (), and the first and second web layers are secured to the antenna support structure to define a curved three dimensional surface.

Multi-layer highly RF reflective flexible mesh surface and reflector antenna

A space deployable antenna reflector surface is formed as a continuous laminate that is shaped to conform with a prescribed energy-focusing surface geometry. The laminate is formed of very thin layers of flexible material, such as very thin sheets of graphite epoxy, containing collapsible radial and perimeter stiffening regions or stiffeners. Due to its thinness, the reflector laminate is collapsible into a folded shape, that facilitates stowage in a restricted volume, such as aboard the space shuttle. The stiffening elements of the laminate antenna structure of the invention facilitate deploying and maintaining the reflector in its intended geometric shape, and collapsing the reflector laminate into a compact serpentine stowed configuration.
