Design and Performance Analysis of Graphene Based Tera Hertz Patch Antenna for 6G Applications

The demand for high data rates in wireless communication is steadily increasing. To fulfill the requirements, 6G will play a vital role, and it can be achieved by a wide range of spectrums. So, to overcome the data rate problem, in this research, a graphene-based antenna is designed for 6G communication. The performance of the antenna is improved by minimizing the return loss of the antenna. The design incorporates graphene, a two-dimensional material, into the patch structure of the antenna. Various substrates, including FR4, Rogers RO3003, and Rogers RO3010, have been considered, and the antenna dimensions are fixed at 15 × 20 µm². Upon comprehensive analysis, the outcomes reveal particularly promising results for the FR4 substrate, demonstrating a return loss of -67.87 dB at 8.704 THz. However, the most notable performance is observed with the Rogers RO3003 substrate, showcasing an impressive return loss of -75.92 dB at 8.552 THz, coupled with a VSWR value of 1.0003198. The comprehensive design was carried out using CST Studio. These findings position the proposed antenna as an optimum choice for a range of applications, including short-range high-frequency communication, terahertz imaging and sensing, airspace communication, and healthcare applications.
