Problems solved by technology

However, the conductivity of graphene has a huge imaginary part in the terahertz band, which causes the internal current of graphene to be converted into heat energy, which seriously affects the efficiency of the antenna, which seriously hinders the application of graphene antennas in terahertz antennas.

Abstract

The invention discloses a reconfigurable Terahertz antenna based on a graphene-metal structure and a frequency modulation method. According to the antenna, a novel mixed graphene-metal structure radiating surface is adopted to improve a traditional pure metal antenna, and the mixed graphene-metal structure radiating surface comprises a graphene tuning part and a metal radiating body. According to the antenna, dynamic reconstruction can be carried out by changing the electric field bias of the graphene tuning part of the antenna radiating surface, and the antenna has a low reflection coefficient. In addition, due to the fact that the radiation patch of the antenna reserves a traditional metal material, the radiation performance of a traditional metal antenna is greatly balanced. The provided mixed graphene-metal reconfigurable antenna is expected to enable a gradient plane slot antenna to be used in a higher frequency band, and graphene brings more possibilities and an expansion space for a design and an application of the Terahertz antenna.

Description

technical field [0001] The invention belongs to the field of terahertz antennas, and relates to a graphene-metal structure-based reconfigurable terahertz antenna and a frequency modulation method. Background technique [0002] In recent years, ultra-wideband antennas have been widely used in biomedical detection, radar systems, and wireless communications. Among them, the graded planar slot antenna is regarded as one of the best choices for realizing ultra-wideband technology due to its highly directional radiation pattern, ultra-wide bandwidth, and low cross-polarization. [0003] As a key wireless technology, terahertz communication has been widely used in classic network scenarios and new generation wireless communication due to its good image analysis ability and unique penetration. In recent years, the performance of tapered planar slot antennas has been extended to high gain and miniaturization. However, tapered planar slot antennas are rarely used in the terahertz fr...
