Abstract—This paper presents a design of a compact annular ring microstrip antenna using a modified graphene material with short-pin technique. The antenna design uses graphene material in parts of patch and ground plane of an annular ring antenna. The form factor of the antenna is designed for 2.4 GHz bands by adjusting the outer and inner radius using the short-pin technique to evaluate the resonant frequency. The simulation considers the return loss and directional radiation pattern in the feasibility analysis. The simulation results show that the form factor of the antenna in the proposed model can be adjusted to support 2.4 GHz bands with the return loss at −54.07 dB which is potentially feasible for various applications such as mobile phone, bluetooth, and radar in wireless communication devices
