Final Report Summary - RETINA (Reliable, tuneable and inexpensive antennas by collective fabrication processes)
The RETINA demonstrator would consist of 20 to 30 unitary cells, compared with around 1000 cells envisioned for the future target product. Thorough attention was paid to the issue of reliability in terms of temperature, vibrations and signal strength. Therefore, extensive tests on the reliability of both technologies accompanied the different stages of the project and extra efforts were invested with respect to the proper modeling of the main reliability aspects by developing a suitable software tool.
A successful development of advanced phase shifting technologies such as RF-MEMS and ferroelectric capacitors was performed which led to the realisation of a partial reflect array antenna, demonstrating electrical beam steering in the operational SatCom bandwidth. The project built the foundation for the development of a full-scale Ku band SatCom antenna with the potential of advanced electrical beam-steering using low-cost fabrication processes.
