In this paper, we discuss the process to fabricate a microstrip patch antenna by using graphene as a substrate material. Ours is the age of modern technology. Wireless communication is one of them. In wireless communication, graphene is widely used in the twenty-first century. Microstrip patch antenna provides better performance and better anticipation compared to other antennas. Microstrip patch antennas are more preferable compared to others because of their low cost, small size, and high performance. The graphene has a reconfigurable surface conductivity that can be tuned to operate at the desired frequencies. The main concept we focus on here to locate the best feed point of a microstrip patch antenna. This paper represents a graphene-based microstrip patch antenna. It has a 2.45 GHz resonant frequency for wireless communication. Here we use CST STUDIO SUITE 2017 software for designing and simulation our antenna. It shows the voltage standing wave ratio (VSWR), return loss, H-plane radiation pattern, and input impedance. The simulation output result shows a gain 6.801 dB and directivity of 7.302 dBi. It has return loss -23.673dB. Finally, we build up a design process of a graphene-based microstrip patch antenna.
