Abstract
A shaped reflector antenna synthesis, making, use of physical-optics diffraction in conjunction with a pseudospline global description of the reflector surface is presented for the proposed C and Ku-bands coverage of the South American territory by BRASILSAT B3 satellite. Unique features of the synthesis technique are shown to substantially reduce the computational effort to attend specified main and exterior bounds of coverage areas at two frequencies of the chosen band of operation simultaneously
