PARIS (ESA PR) — The traditional curved antenna reflector is instantly recognisable on a satellite, but also represents one of the bulkiest elements aboard. As an alternative, new ESA-backed software allows antenna designers to achieve comparable radio frequency performance from flatter, smarter ‘reflectarrays’, which can be manufactured cheaply, just like printed circuits. Two forthcoming ESA missions will demonstrate reflectarray antennas, one in Earth orbit and the other into deep space.

PARIS (ESA PR) — This replica model of ESA’s ‘Miniaturised Asteroid Remote Geophysical Observer’, or M-Argo, was on display at the Agency’s recent  Antennas workshop. It is the one of numerous small missions planned as part of in ESA’s Technology Strategy, being presented at this month’s  Space19+  Council at Ministerial Level.
