Abstract—In this paper, the design process of an annular ring microstrip antenna using graphene material for dual-band applications is proposed. The microstrip antenna is modified using graphene-based annular ring microstrip layers for patch and ground plane with FR-4 epoxy substrate in between and simulated by the EMCoS software. The design process applied the short-pin technique for the estimation of the return loss, which leads to the analysis of the resonant frequency and the dual-band directions. The evaluation shows the acceptable performance in the frequency range of two resonant positions with the return loss of -29.33 dB at 2.4 GHz in ISM-band and the return loss of -39.49 dB at 5.3 GHz in C-band. However, the modified antenna offers several advantages such as low profile, low cost and small size (40 x 40 mm²).
