INFLATABLE SUPPORTING REFLECTOR ANTENNA

摘要

PROBLEM TO BE SOLVED: To surely support an antenna by forming a concave surface necessary for radio wave reflection, even if a flexible film is used for a radio wave reflecting surface. SOLUTION: The antenna comprises a truss structure in which a sheet 1 having conductivity and forming a concave surface for reflecting radio waves and a tube-like inflatable structure are combined. The antenna is provided with a frame 4 having a plurality of supporting portions 42 for supporting the film 1 at positions in conformity with a desired curvature. The concave surface of a desired curvature is formed in the film 1 by supporting the film 1 by the supporting portions 42 of the frame 4. COPYRIGHT: (C)2004,JPO&NCIPI
