New generation of S, X and all Global Navigation Satellite System bands miniature high-performance antennas for SmallSats.

Country of Origin: France
Reference Number: TOFR20190809001
Publication Date: 29 August 2019


The French SME designs and manufactures a new generation of miniature, high-performance and high-quality antennas for space applications using SmallSats. 
The company has developed compact and lightweight new S, X and all GNSS (Global Navigation Satellite System) bands antennas and is looking for space agencies, universities, space suppliers for technical or R&D cooperation in the development or improvement of antennas.


Antennas are key equipment for many applications: telecommunications, navigation, radar, … With the growing demand in the NewSpace sector, particularly for SmallSats, there is a need for a new generation of antennas, smaller and lighter than those for traditional satellite.

A French SME, spin-off of the French Space agency, has designed and developed three compact and lightweight antennas suited for small satellites in Low Earth Orbit (LEO):

- X-band antenna optimised for high data rate payload telemetry
It is used to repatriate a large amount of payload data at high data rate to the Earth ground stations.

- S-band antenna optimised for telemetry (TM) and telecommand (TC)
It is used to control the satellite, to send instructions about manoeuvres and data to be recorded, and to monitor the satellite health.

- All GNSS bands antenna
It is used to cover worldwide navigation systems (GPS, Galileo, Glonass, Beidou and Inmarsat in L-band for Precise Point Positioning).

Both antennas in S- and X-bands will be put into orbit in quarter 4 2019.

The company has a breakthrough technology relying on the ceramic material selected and how it is structured thanks to 3D printing.

The company can also provide its expertise for bespoke antenna development and antenna simulation, stand-alone or in their operating environment (integrated on the small carrier).

The company is looking for industrial and academic partners to further develop antennas, mainly for NewSpace applications but also in other sectors (drones, defense, autonomous vehicles…). Technical cooperation is sought with NewSpace companies (SmallSats integrators but also companies specialised in space equipments such as amplifiers, modems, transponders…), space agencies, universities.

The SME is also open to R&D cooperation in the frame of European calls for proposals like Horizon 2020.
