Problems solved by technology

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

Abstract

The invention discloses a graphene-based directional diagram and frequency reconfigurable microstrip antenna and a 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. Results show that the antenna provided by the invention can be dynamically reconstructed by changing the electric field bias of the graphene tuning part of the antenna radiation surface, and the radiation patch of the dipole antenna retains the traditional metal material, so that the radiation performance of the traditional metal antenna is greatly balanced. Besides, on the basis of the special property of the graphene material, the antenna can specifically control the pairs of director structures in the antenna, and the directional diagram of the microstrip dipole antenna can be reconfigured by controlling the director effects of different director structures.

Description

technical field [0001] The invention belongs to the field of reconfigurable microstrip antennas, and relates to a graphene-based microstrip antenna and a method for reconfigurable pattern and frequency. Background technique [0002] Automobiles have evolved tremendously since the second industrial revolution. Nowadays, cars have become indispensable, and with the rapid development of information and communication technology, people's attention to cars is no longer just quality. The next frontier of the automotive revolution is equipping vehicles with wireless communications. [0003] With the rapid development of automobiles, there are more and more sensors on automobiles. At present, there are about 100 sensors on a car. With the improvement of car intelligence and automation, the number of sensors is expected to double in the next few years. Therefore, it is very necessary to apply nano-antennas to car communication. . In the terahertz frequency band, antennas will be ...
