Terahertz Micro-Strip Patch Antenna Design and Modelling for 6G Mobile Communication (Nov, 10.1007/s42835-022-01308-8, 2022)

The future mobile communication networks are emerging drastically and research is being pursued all around the world. To match with the increasing demand for high-speed data communication, wide bandwidth and a high gain antenna are required. Therefore, in this work, the frequency above 100 GHz is chosen as it provides high bandwidth and also suitable for short range communication. Initially, we have designed an antenna with carrier frequency of 300 GHz by comparing it with three different patch materials like Copper, Graphene and Gold and the antenna parameters are analysed. The obtained result shows that the graphene patch has a return loss of −27.70 dB, maximum bandwidth of 10.4 GHz and ideal radiation efficiency of 98.38%. Then the link budget evaluation for the target data rate is 100 Gbps at the bandwidth of 30 GHz on 10 m link distance is analyzed for mobile communication. By executing link budget evaluations in terms of code rate, target SNR, path loss and number of antenna elements required are validated. Finally, the proposed link budget is verified for various modulation schemes using MATLAB. © 2022, The Author(s) under exclusive licence to The Korean Institute of Electrical Engineers.
