本発明は人工衛星搭載用の構造体に適用する材料の改良
に関し、特にアンテナ等のカバーに使用する帯電防止膜
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the improvement of materials applied to structures for mounting on artificial satellites, and particularly to antistatic films used for covers of antennas and the like.

ため、この種の帯電防止膜をそのままアンテナのカバー
として用いることは出来ず、アンテナにおける有効な帯
電防止を図ることが困難であった。The conventional antistatic film described above can prevent static electricity charging, but because the electrical resistance of the film is low at 10-1 to io-''Ωcm, the transmittance of radio waves is low. In this case, the amount of attenuation becomes as high as 35 dB or more.For this reason, this type of antistatic film cannot be used as it is as a cover for an antenna, and it has been difficult to effectively prevent static electricity in the antenna.
本発明は、アンテナの帯電防止膜として有効な電波透過
性帯電防止膜を提供することを目的としている。An object of the present invention is to provide a radio wave transparent antistatic film that is effective as an antistatic film for an antenna.

。(Unit: KV) As you can see, by forming a germanium thin film on GFRP, which is a radio wave insulator, it becomes radio transparent and has a small amount of electrostatic charge, so it can be used in space like an artificial satellite. It can be used as a cover for areas that are charged with static electricity and would cause problems if sparks occur.
