Abstract :
The concept and analysis of a graphene-metal reconfigurable terahertz dipole antenna are presented. The hybrid graphene-metal implementation is proposed to combine i) dynamic frequency reconfiguration using graphene field effect and ii) high radiation efficiency enabled by metal. The good direct matching to terahertz continuous wave sources, the large tuning range, and the improved efficiency demonstrate that graphene-metal structures are very promising for reconfigurable terahertz antennas.
