3D-Printed K/Ka-Band Antenna-Feed System with Built-In RF, Thermal and Mechanical Functionalities
This paper presents the results of an R&D activity, funded by the ARTES Advance Technology programme of the European Space Agency, aimed at integrating RF, thermal and mechanical functions in a monolithic K/Ka-band antenna-feed assembly through Additive Manufacturing (AM) for GEO High Throughput Satellites (HTS). After a trade-off analysis between different configurations, an AM-oriented version of an asymmetric antenna-feed architecture was selected and realized by the laser-based powder bed fusion of metals (PBF-LB/M) process. The prototype was successfully tested for Radio-Frequency (RF), thermal and mechanical performances.
