Marco Sabbadini: Smart skin for flat antennas

A revolutionary new type of flat antenna is on its way to space, explains Marco Sabbadini, Senior Antenna engineer in ESA’s Antenna and Sub-Millimetre Waves Section. Normally antennas have a curved reflector dish – which works rather like the rounded surrounding of a flashlight to focus its beam towards its target – as well as a radio signal feed horn. The new ‘modulated metasurface’ antenna influences electromagnetic radiation not through the reflector’s curvature but by careful tailoring of the surface itself.
