Abstract :
This paper presents an initial study of reconfigurable antennas made of graphene for multi-band wireless communications applications. A simple microstrip patch antenna with graphene extensions on its sides has been analysed for Wireless Fidelity (WIFI) operational bands, and another microstrip patch antenna with inset notches filled with graphene strips has been evaluated for Long Term Evolution (LTE) applications. The graphene sheet resistances are changed to activate or deactivate parts of the antenna via DC voltage bias. This changes the effective lengths of the antennas, and therefore, their resonant frequencies.
