This work presents a graphene antenna composed by a planar dipole and a circular loop for increasing bandwidth in the terahertz range. The dipole is fed by a voltage source in its gap and the circular loop is a parasitic antenna without physical connection with dipole. The two-dimensional method of moments (MoM-2D) with surface impedance is used for numerical analysis of this antenna compound antenna. It is investigated the influence of geometry and the chemical potential of loop element on the input impedance and bandwidth of the dipole element, with objective to obtain broadband operation. |
