Abstract:
For today's high and very high throughput satellites (HTS and VHTS), the requirements for the communication capacity and flexibility have increased continuously. In order to meet these requirements and to provide maximum flexibility, active antennas are used for user beams nowadays. The active components have to be applicable to multiple beams. Typical approaches are focused or defocused arrayfed reflector antennas using the multiple-feeds-per-beam (MFB) principle, imaging phased arrays (IPA) and direct-radiating array antennas (ORA).
Some of these approaches lead to very large feed clusters with tight fie!d spacing. Manufacturing of such complex feed clusters poses a challenge using conventional manufacturing methods. A first approach to solve these problems is an increasing use of additive manufacturing technologies like direct metal laser sintering.
In order to utilize the additional degrees of freedom provided by such a manufacturing process, a nonparametric optimization strategy is followed by combining CST Studio Suite and Tosca. The combination of the adjoint sensitivity computation in a full wave simulation and the shape optimization method, allows the improvement in performance of various key components for aerospace antenna systems.
