Funkwellendurchlässige Sonnenschutzfolie und geschützte Gegenstände

摘要

A structure protected by a sunshield film (20) includes an article (32), for example a spacecraft radio-frequency antenna, and a sunshield film (20) protecting the article surface (34). The sunshield film (20) is formed as a sheet substrate (22) made of a material that is transparent to radio frequency energy, a white coating (28) on one side of the sheet substrate (22), and a black coating (30) on the other side of the sheet substrate (22). The white coating (28) and the black coating (30) each have a surface resistivity of from about 10<8> to about 10<9> ohms per square.
