[pt] This work investigates the synthesis of dual-reflector antennas for omnidirectional coverage. Both reflectors are bodies-of-revolution: the subreflector is generated by a single conic section while the shaped main reflector is generated by a series of local conic sections which are consecutively concatenated. The main-reflector is shaped to radiate, under GO principles, a prescribed power density in the elevation plane. To illustrate the method, two representative omnidirectional axisdisplaced Cassegrain configurations are synthesized. The GO shaping results are validated by method-of-moments simulations.
