Reconfigurable metasurfaces, characterized by electromagnetic properties that can be controlled in both space and time, allow conceiving a new generation of smart antennas (Smart Antennas 2.0), whose intelligence is brought by the physical layer rather than by the connected signal processing modules, as it happens for conventional smart antennas. In particular, by combining either stand-alone or array antennas with reconfigurable metasurfaces, we can enhance the antenna functionalities, enabling cognitive and awareness capabilities, as well as a dynamic control of both radiating and electrical properties. The fundamental bricks of this idea will be presented and discussed, considering the examples of single monopole radiators and planar antenna arrays.

Abstract
Reconfigurable metasurfaces, characterized by electromagnetic properties that can be controlled in both space and time, allow conceiving a new generation of smart antennas (Smart Antennas 2.0), whose intelligence is brought by the physical layer rather than by the connected signal processing modules, as it happens for conventional smart antennas. In particular, by combining either stand-alone or array antennas with reconfigurable metasurfaces, we can enhance the antenna functionalities, enabling cognitive and awareness capabilities, as well as a dynamic control of both radiating and electrical properties. The fundamental bricks of this idea will be presented and discussed, considering the examples of single monopole radiators and planar antenna arrays.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
