Abstract
A computer simulation is described for the production of multiple beams by a dual-offset reflector antenna with a feed consisting of a circular waveguide array. It is shown that acceptable efficiencies and low crosspolar levels can be achieved for two sample beams of a multibeam configuration by deriving the array excitation from the focal-region fields of the double-offset antenna.
