Abstract

The invention provides an adjustable-beam graphene wave leakage antenna. The adjustable-beam graphene wave leakage antenna can be used for generating wave leakage radiation of which beam is biased andis adjustable with an applied voltage and can cover a frequency band mainly being a low-terahertz frequency band, the volume size of the antenna under a 2THz frequency is 480 micrometers by 150 micrometers by 20 micrometers. The antenna mainly comprises an antenna radiation unit, a graphene voltage bias system and metal ground. The antenna has the advantages of small size, adjustable beam directional angle, relatively high gain and the like.

Description

technical field [0001] The present invention relates to a graphene leaky-wave antenna, in particular to a graphene leaky-wave antenna with adjustable beams, especially a graphene strip spacing that changes periodically and the beam direction of the leaky-wave antenna changes with the applied voltage bias Program. Background technique [0002] Graphene is a two-dimensional crystal composed of carbon atoms with only one atomic thickness. As a two-dimensional material with excellent crystal quality and electronic properties, graphene exhibits unique electronic transport, optical coupling, electromagnetics and other Novelty in nature. In the field of antennas in the terahertz frequency band, graphene has the advantages of low loss and adjustable surface conductivity with the applied electric and magnetic fields, and has great application prospects. [0003] There have been researches on graphene leaky-wave antennas abroad, and an article about graphene leaky-wave antennas publ...
