基于石墨烯片的频率可调太赫兹天线
Frequency Tunable Terahertz Antenna Based on Graphene Sheet
摘要
Abstract
In this paper,we propose a reconfigurable antenna using graphene which can work in terahertz band.The antenna use folded slot structure and coplanar waveguide to achieve impedance matching easily.By adjusting the conduc-tivity of the four graphene sheets added between the slots,we can change the resonant frequencies of the antenna from 230.5 GHz to 270.5 GHz.In addition,a metasurface consisted of square closed-ring resonators(CRR)is under the antenna used to increase the gain of antenna.Because of the reflection of metasurface,the gain of antenna in two work mode in-creases 2.48 dBi and 3.55 dBi respectively.关键词
