Low dielectric, low loss radomes and materials for low dielectric, low loss radomes

A material for a radome, the material comprising a filler within a matrix, the filler reducing overall dielectric constant, wherein:

• the resin matrix comprises a PC/PET blend of polycarbonate (PC) and polyethylene terephthalate (PET);
• the material has a dielectric constant less than 2 at frequencies up to 90 GHz;
• the material has a loss tangent less than 0.01 at frequencies up to 90 GHz;
• the material has a UL94 flame rating of V0;
• and
• the material is injection moldable.

A material suitable for a radome, the material comprising a filler and one or more impact modifiers within a resin matrix, the filler reducing overall dielectric constant, wherein:

• the one or more impact modifiers comprise one or more of acrylic styrene acrylonitrile, methacrylate butadiene styrene terpolymer, acrylate polymethacrylate copolymer, chlorinated polyethylene, ethylene vinyl acetate copolymer, acrylonitrile butadiene styrene terpolymer, and/or polyacrylate, wherein:
• the material has a dielectric constant less than 2 at frequencies up to 90 GHz;
• the material has a loss tangent less than 0.01 at frequencies up to 90 GHz;
• the material has a UL94 flame rating of V0;
• and
• the material is injection moldable.
