Abstract
By depositing a layer of graphene on the top of SiO
2
/Si substrate
a terahertz(THz)tunable dipole antenna with dual frequency characteristics is designed based on the controllable conductivity of graphene by its own chemical potential.The antenna can switch six resonant modes and achieve a continuous adjustable range of 26 GHz near 1.1 THz.In addition
by adjusting the chemical potential
the radiation gain of the antenna increases from 2.33 dBi to 3.65 dBi
showing good radiation performance
which will be widely used in the design of THz reconfigurable antenna and antenna array.
