We propose a reconfigurable scheme consisting of an antenna loaded by a CVD graphene capacitor. We show how the gated-graphene can actively control the antenna gain by about 2-3 dB and the phase of far-field electric field by about 45°. The proposed idea could be efficiently adapted to antennas with different geometries and operating frequencies becoming transparent with respect to antenna technologies. We believe that these results clear a path toward graphene-based antenna systems for reconfigurable and smart telecommunication systems.

Abstract
We propose a reconfigurable scheme consisting of an antenna loaded by a CVD graphene capacitor. We show how the gated-graphene can actively control the antenna gain by about 2-3 dB and the phase of far-field electric field by about 45°. The proposed idea could be efficiently adapted to antennas with different geometries and operating frequencies becoming transparent with respect to antenna technologies. We believe that these results clear a path toward graphene-based antenna systems for reconfigurable and smart telecommunication systems.File in questo prodotto:
