Summary:PROBLEM TO BE SOLVED: To provide an expandable film antenna for the outer space provided with a precise, inexpensive and reliably developed antenna mirror surface. SOLUTION: In the expandable film antenna for the outer space having a balloon film and an annular support positioned outside the periphery of the balloon film to support the balloon film, the annular support has synchronous development truss structure where constituting members are uniforms and developed at a controlled speed and the whole shape is deformed and developed similarly. Furthermore, a grid network formed of dielectric thin wires is connected to the outer surface of one or both of a film on a radio wave entering side and a film on a radio wave reflecting side.
