Quick summary

Objectives: The objective of this activity is to develop and test a Ka-band sparse active transmit antenna breadboard and associated beamforming network for ground terminals to be connected with satellites in orbits ranging from geostationary orbits to low earth orbit orbits. Targeted Improvements include a 25% reduction in the number of active controls, a 5% increase in the DC-to-RF power efficiency at antenna level due to reduced exploitation of amplitude tapering, and a 15% reduction in the overall mass for the entire antenna.
Eligibility criteria: This tender is open to tenderers from AT, BE, CA, CH, CZ, DE, DK, GR, ES, FI, FR, GB, HU, IE, IT, LU, NL, NO, PL, PT, RO, SE. It is an open competition with no ECOS requirement and not classif...
