Study of software for optimization of contoured beam reflector antennas. Volume 1: Summary report
Abstract
High-gain antennas with contoured beams are envisaged in future satellite systems, e.g., telecommunications and direct broadcast. The principal contoured-beam antenna concept considered involves the use of a large reflector system in combination with a multiple-feed array. The synthesis software developed under a previous contract was updated and validated. Detailed instruction for the use of the software is given. Extensive comparisons were carried out for two experimental test cases involving measured primary and secondary patterns. To demonstrate an alternative to the reflector antenna with a multi-element feed array in case of a fixed contoured beam, the limitations of shaped single reflectors were examined.
