Compact Antennas for Nano- and Micro- satellites: development and future antenna needs at CNES

CNES started developments on miniaturized antennas for small platforms in 2010s (spectrum survey, MASCOT lander). More recently, compact and wideband antennas for TT&C were designed, manufactured and tested for cubesats needs. Over the last two years, besides the development of Angels nanosatellite, a demonstrator of Argos miniaturized technologies, CNES has supported several activities on this topic. Resulting antenna designs and performances are briefly presented in this paper. Finally, new challenges and perspectives for cubesats antennas, as envisioned by CNES, are discussed.
