Towards Accelerating the Feed Design of a Series of Different Reflector Antennas

We introduce a surrogate-based model to reduce the simulation and design time of the full system radiation pattern of a reflector antenna. The technique is applied in the context where feeds are to be designed for a series of similar, but different, reflector antenna systems. One reflector system is selected as the reference antenna, and its pattern is completely simulated over the required design space. The resulting information is used to inform the design of other reflectors, which are simulated only sparsely in their design space. In this paper, we show that the reference antenna could have a different focal distance compared to the original antenna and that a single reflector antenna could be used as a reference for a dual reflector system.
