The simulation output shows a minimal return loss − 59.97 dB, VSWR 1.007, and good radiation pattern at 0.72 THz resonant frequency, which would be an excellent candidate for future wireless communication as well as medical imaging, homeland defense system, explosive detection, and material characterization application. The designing and simulation are performed using a full-wave electromagnetic simulator CST microwave studio based on the finite difference time domain method. The result is demonstrated in terms of return loss (s11 < − 10 dB), voltage standing wave ratio (VSWR), input impedance, E-plane, and H-plane radiation pattern. The proposed antenna shows 37.50% impedance bandwidth ranging from 0.53 to 0.84 THz at the center frequency of 0.72 THz. This paper presents a graphene-based microstrip patch antenna at 0.72 THz resonant frequency for wireless communication. In the twenty-first century, graphene is widely used in wireless communication, especially in terahertz applications because of its amazing electrical, mechanical, and optical properties.
