摘要：

The work presents a geometrical optics (GO) synthesis of a circularly symmetric dual-reflector Cassegrain antenna, shaped to provide a uniform coverage of Earth's surface by means of a ISOFLUX radiation pattern when such antenna is embarked in a low orbit satellite. This is attained by the simultaneous control of the amplitude and phase of the GO field at the main-reflector aperture. A full-wave method of moments (MoM) analysis is further conducted to validate the shaping procedure.
