The invention discloses a reconfigurable terahertz antenna based on a graphene-metal structure and a frequency modulation method. The antenna of the present invention adopts a novel hybrid graphene-metal structure radiation surface to improve the traditional pure metal antenna, and the hybrid graphene-metal structure radiation surface includes a graphene tuning part and a metal radiator. The antenna of the invention can be dynamically reconstructed by changing the electric field bias of the graphene tuning part of the antenna radiation surface, and has a lower reflection coefficient. In addition, since the radiation patch of the antenna of the present invention retains the traditional metal material, the radiation performance of the traditional metal antenna is greatly balanced. The proposed hybrid graphene-metal reconfigurable antenna is expected to enable the use of graded planar slot antennas in higher frequency bands, and enable graphene to bring more possibilities and expansion space for the design and application of terahertz antennas. |
