PROBLEM TO BE SOLVED: To realize an expanding antenna which is large and lightweight and maintains the curvature of a concave surface used for radio wave reflection. SOLUTION: The inflatable reflector antenna consists of two films 1, 2 whose circumferential parts are connected with each other over the entire circumference, wherein the film 2 has conductivity, the film 1 has radio wave transparency, and the film 2 expands as a concave surface for reflecting radio waves when a main body inner chamber to be airtightly formed by these films is filled with gas to form a balloon-like structure. A resin which is cured after the concave surface expands is used as the film 2. COPYRIGHT: (C)2004,JPO&NCIPI
