    摘要: The invention is directed to a method of producing a decorative radome, comprising providing a substrate having a first surface and a second surface; applying, to at least a portion of the second surface of the substrate, a decorative layer comprising a layer of a metal or an alloy comprising a metal and a metalloid; and overmolding at least the decorative layer with a radio-transmissive polymer to provide an overmolded layer as well as a decorative radome comprising a first layer comprising a, preferably radio-transmissive, polymer, the first layer having a front surface; a second layer comprising a, preferably radio-transmissive, polymer, the second layer having a rear surface; and a decorative layer, between at least a portion of the first and second layer, comprising a layer of metal or an alloy comprising a metal and a metalloid, wherein the second layer directly or indirectly abuts the decorative layer and is directly adhesion bound or indirectly connected to the first layer, and wherein at least one of the first or second layers is comprised of a polymer capable of being formed by overmolding at a barrel nozzle temperature below 300 degrees Celsius.

    摘要: The invention relates to a cover (1, 101, 301) for at least one antenna (11, 111) emitting and/or sensing electromagnetic radiation in at least one first frequency band, the cover (1, 101, 301) comprising at least one first surface facing the antenna (11, 111) and at least one second surface averted to the antenna (11, 111), wherein the cover (1, 101, 301) comprises at least one substrate (3, 103) being transmissible for electromagnetic radiation and at least one first coating (7, 107) covering the substrate (3, 103) in at least one first area (19, 119), the first coating (7, 107) being transmissible for electromagnetic radiation of at least the first frequency band, whereas the first coating (7, 107) is reflective for electromagnetic radiation falling onto the second surface and having a frequency within at least one second frequency band.
