PROBLEM TO BE SOLVED: To provide the joining structure of a radio wave reflector in which the number of parts is small, assembling workability is satisfactory, rigidity against wind pressure and anti-earthquake performance are excellent, side lobe suppression is improved, and antenna characteristics are satisfactory. SOLUTION: The parabolic antenna apparatus has at least a redome having a radio wave absorber in at least one part of the internal surface, and a radio wave reflector coupled to the redome. Radio waves leaking to the outside of the radio wave reflector are absorbed by the radio wave absorber and converged into a primary radiator while reducing the side lobe. COPYRIGHT: (C)2006,JPO&NCIPI
