Rectangular dielectric resonator antennas with a thin graphene film
2017
This paper presents the study of rectangular dielectric resonator antennas (DRAs) with a thin graphene film placed on the top surface of the resonator. The effect of the graphene film with different conductivities on the |S11| response and antenna gain of the rectangular DRAs is investigated. Both 50% and 100% graphene film coverage cases on the top surface of the DRA are considered. In the latter case, the dielectric resonator antenna is transformed into a microstrip antenna. For both cases, simulation and experimental results are presented. The results show that the graphene film conductivity has a significant effect on the performance of the DRA.
