An ESA project has developed satellite antenna the size of a small picture frame, intended for miniature CubeSats. Built by Polish company WiRan the antenna found its first customer as soon as it was finalised, and is already serving in space. Measuring less than 10 x 10 x 3 cm, including its connector, this new S-band antenna is designed for ‘telemetry, tracking and command’ purposes, meaning it will be used for uplinking commands to a CubeSat and downlinking platform and payload data.
