Abstract
A frequency and radiation pattern reconfigurable antenna based on graphene at terahertz band is presented in this paper. By applying different chemical potentials on the one arm of the proposed antenna while keeping it unchanged of the other arm, the antenna can operate at 1-2 THz, and the obtained maximum impedance bandwidth can be up to 26.68 %. Radiation patterns of the proposed antenna can also be controlled by the applied chemical potentials, which makes it very promising for beam-scanning in terahertz systems or devices.
