This study proposes a new idea for designing antenna based on graphene for THz application in detailed analysis. Here, design of a novel graphene‐based ribbon antenna is presented based on surface plasmon polariton (SPP) behavioural in graphene. Noble metals support and confine EM waves in infrared region. However, SPP wave propagation is supported by graphene in much lower frequencies of infrared region, in THz region. The conductivity of graphene and SPP waves behavioural in graphene sheet is analysed and studied for designing antenna based on new idea of ribbon antenna. The numerical simulations with COMSOL and CST are presented in proposed new idea structure of antenna. In order to achieve the desired tunable THz band communication, the parametric study method is used for the proposed graphene‐based ribbon antenna to achieve higher efficiency.

In this paper, a novel design for planar plate monopole antennas is proposed with applications to ultra-wide band (UWB) communications. To verify the proposed antenna design, simulations are performed by means of CST and HFSS software tools, showing that the impedance bandwidth is significantly increased by vertical cross-sections. By adding a series of parameters to the vertical crosssections, the antenna efficiency is effectively enhanced by achieving a return loss of 10 dB over the bandwidth range between 3.1 GHz and 10.6 GHz. In addition, our experimental results demonstrate that the fabricated antenna has a return loss performance similar to that obtained by the simulation results.
