Development of a Shared Aperture Ka Band User Terminal Antenna for Nomadic and Transportable IRIS² Use Cases

The European Space Agency (ESA) is procuring the development of a shared aperture Ka-band user terminal antenna for nomadic and transportable IRIS² use cases. The project involves design, development, and testing of a multi-beam antenna system capable of operating in both geostationary and low Earth orbit satellite networks. Key deliverables include a prototype antenna with beam steering, tracking, and polarization agility. The contract is expected to be awarded to a single entity or consortium with proven experience in satellite communications antenna development. The duration is estimated at 24 months with a total budget of approximately €2 million.
