Graphene patch array antenna at 60 GHz for 5G Millimeter-Wave Communications

In this paper, an improved Wave Concept Iterative Process method is used to simulate a graphene patch array antenna for future 5G millimeter-wave communication applications. The antenna array consists of twelve antenna elements which are fed by a 3-to-4 power divider and has a high gain of 14.47 dBi at 60.07 GHz with an excellent return loss. The proposed formulation has shown great efficiency and precision, and it has a shorter computation time than the CST and HFSS simulators.
