We propose a reconfigurable scheme consisting of an antenna loaded by a CVD graphene capacitor.

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 | Dimensione | Formato | |
