Abstract
This paper presents a method for optimally designing the subreflector of a Cassegrain antenna for maximum efficiency while maintaining a low V.S.W.R. level. This is accomplished by setting up a composite performance criterion which explicitly includes both the efficiency and the power reflected back into the feed. Gradient search procedures are then used to find the subreflector shape to maximise this criterion. Broad band design is possible simply by integrating the criterion over the required frequency interval. Theoretical and experimental results are given for a small two-reflector antenna.
