Abstract: The need for high-speed transmission of information has extensively increased in today’s wireless and communication world. For an effective antenna design, material, and peripheral circuit to it are important parameters to attain high speed and effective transmission. It is investigated that conventional copper-based antennas are limited by various non-ideal effects at high-frequency operations. Consequently, this has triggered a lot of researches to investigate new materials that can work efficiently at high frequencies with considerable small latency and high bandwidth. It has been vividly explored that graphene is a prominent alternative to traditional copper material owing to its significantly high physical, chemical, thermal and mechanical properties. The graphene-based antennas possess high potential. However, this has been very marginally explored till date. This has been henceforward excitingly taken up in current work. In the present work, a rectangular inset-fed graphene-based patch antenna at 7 terahertz (THz) frequency has been designed. Further, the performance of graphene-based antenna is examined with different substrate materials like glass, teflon, silicon-dioxide, and quartz. It is analyzed that silicon dioxide and quartz substrates give remarkable return loss and high gain. It is also observed that if the patch is sandwiched between substrate and superstrate, then the performance of the antenna can be further improved in terms of gain and directivity. Mathematical analysis using FDTD (Finite Difference Time Domain) has also been explored for copper based microstrip patch antenna. The FDTD technique has been learnt during the project and result has been observed.
