Reflector antennas have been used since the discovery of electromagnetic wave propagation by Hertz in 1888. It was only in the days of World War 2, however, that detailed design and analysis techniques were established for microwave radar applications. Deep space communication in the 1960s ensured that the reflector antenna became a household name. Two collections of important papers on reflector and horn antennas have been published by the IEEE Press [Love].

The most popular configurations include plane, corner, and curved reflectors. Paraboloidal reflectors are the most widely used large aperture ground-based antennas, according to Clarricoats and Poulton.

This type of antenna is widely used for low-noise applications, such as radioastronomy, and it is considered as a good compromise between performance and cost, e.g. Balanis....

In the antenna presented here, the physical feed antenna is substituted by a theoretical / simulated / measured pattern, simplifying the overall model. Simulation accuracy is relaxed in favor of improved runtimes.
