Abstract: This presentation provides an overview of recent multiple beam lens antenna developments supported by the European Space Agency, for applications ranging from satcom payloads, to imaging systems and microwave instruments. There are also on-going transfer of technology activities for 5G terrestrial communication systems. The presentation will cover related developments on polarizers, providing polarization conversion as well as polarization selectivity for advanced antenna systems.
