Abstract :
The synthesis of an offset parabola with array feeds consisting of open-ended waveguides located around the focal point of the reflector is investigated. The approach is based on simulated annealing which has been applied to the analysis to two-dimensional phased arrays. Two cases of aperture distributions, uniform and Taylor with 30-dB sidelobe level, are discussed. Both results seem to be satisfactory
