Abstract :
This paper presents a design study of an offset antenna which employs a spherical main reflector and phase correcting subreflector. Detailed predictions are compared with the measured performance of a prototype design. The antenna provides a sidelobe envelope well within the US Federal Communications Commission specification for small earth stations.
