RESUMO

The mazimization of the gain of cassegrainian or gregorian antennas is generally obtained with the shaping of su-refletor and main reflector. Having in mind easiness of construction and flexibility in the use of feed, an alternative of shaping only the sub-reflector, is presented. In the present work, besides shaping the sub-reflector, the parameters of the paraboloid used as the main reflector, are adjusted to minimize phase erros in the aperture uo to a value that justifies the use of such alternative. Symetrical cassegrain antenas are first considered (chapter 2). In chapter 3, the study is extended to gregorian offset type antennas.
