A sun shield (16) is placed in front of an RF reflector (12) for thermal protection thereof. The shield comprises a Kapton substrate (20) with a thin aluminum capacitive grid (26) on the shield's reflector side (24), and a partially reflecting layer (28) of germanium on its sun side (22). Other materials and combinations thereof may be placed on either or both sides singly or in layers to obtain desired reflectance and thermal energy rejection away from the reflector.
