Abstract

The invention provides a Fabry-Perot resonant antenna based on a graphene patch array structure comprising a graphene layer (1), a dielectric layer (2), a reflecting surface (3) and a waveguide (4); At one end of that waveguide (4), the reflective surface (3) is arrange, and a dielectric layer (2) and a graphene lay (1) are arranged on the side of the reflective surface (3) away from the waveguide(4) in sequence; Wherein the reflective surface (3), the dielectric layer (2) and the graphene layer (1) constitute a Fabry-Perot resonator can adjust the surface conductivity of graphene by applyingan external electric field on both sides of graphene to meet the resonance condition in a certain frequency range. Through multiple reflections and transmissions, the maximum directivity can be achieved in the direction of the edge emission. The invention has the advantages of simple structure, small volume, high directivity, small beam width, and adjustable working frequency of the Fabry-Perot resonance cavity.

Description

technical field [0001] The present invention relates to a Fabry-Perot resonant antenna, in particular to a Fabry-Perot resonant antenna based on a graphene patch array structure, especially to a Fabry-Perot resonant high-directivity antenna based on a graphene patch array structure. Background technique [0002] With the rapid development of communication technology, the complexity and variability of the electromagnetic environment have increased, and antennas as electromagnetic wave transceivers in communication systems are facing new and diverse technical requirements and challenges. Especially for long-distance communication, the performance indicators of antenna gain and directivity are the most important, so research in related fields has gradually attracted the attention of scientific researchers. [0003] To realize the high-gain and high-directivity characteristics of the antenna, a feasible way is to use a resonant cavity structure. By adding a reflector with parti...
