Abstract
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.
Claims12
An electromagnetic reflector comprising:
- a non-knitted, non-metallic single sheet mesh comprising carbon nanotube or graphene having a uniform thickness and an array of openings, wherein the sheet has an electrical conductivity which reflects greater than 95% electromagnetic energy up to 50 GHz, wherein the reflector is connected to an outer ring via Z direction flexures and to a backing structure via an array of X and Y direction flexures, allowing the mesh and the backing structure to move independently of each other.
A method for fabricating an electromagnetic reflector, comprising:
- placing a non-metallic, carbon-based substrate sheet having a uniform planar thickness into a laser cutter system;
- holding the sheet flat in the system with a vacuum;
- ablating portions of the substrate comprising a patterned array of a plurality of openings with a high-energy laser of the laser cutter system according to a subtractive technique fabricating a non-knitted, non-metallic, planar mesh reflector having an electrical conductivity which reflects greater than 95% electromagnetic energy up to 50 GHz;
- removing the patterned mesh reflector from the laser cutter system;
- and mounting the reflector to an outer ring via Z direction flexures and to a backing structure via an array of X and Y direction flexures, allowing the mesh and the backing structure to move independently of each other.
