MANT Reflectarray Antenna
Our deployable MANT-Antenna (Miniaturised Deployable Antenna for Small and Nano Satellites) is a next-generation deployable reflectarray antenna designed for CubeSats (6U, 12U, 16U) and other small satellite platforms. Optimized for Ka-band high-throughput communications, MANT combines compact stowage with superior gain and advanced beam-steering capabilities. MANT is developed in cooperation with Fraunhofer Institute for Integrated Circuits (IIS) under contract to ESA.
