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