Abstract
Future space missions with high-resolution microwave and optical instruments will require more sophisticated data downlink antennas. Anywaves has defined a roadmap to make commercially available an X-band payload data transfer phased array antenna capable of electronic beam steering compatible with typical low Earth orbit small satellite requirements. A key aspect in the development of such a complex product is its validation and acceptance test sequence. While an extensive RF characterization is expected as part of the nominal development, time-efficient validation techniques are required in the production line. This paper explores alternative experimental validation techniques using a partial phased array demonstrator developed in the frame of a recent R&T activity supported by CNES. The preliminary results reported here are considered promising. The following steps will address the automation of a complete acceptance test sequence.
