A metasurface consisting of a mushroom-type electromagnetic band gap structure (EBG) is proposed as a means of reducing the mutual coupling between antenna arrays. By capacitively loading the unit cells, not only is the size of the EBG reduced, but also the port-substitution method can be employed to optimize the antenna-EBG system. Simulation results show improvement of mutual coupling and return loss by allowing the EBG to be optimized in conjunction with the antenna array, rather than designing them separately and then combining them together after the fact. A mutual coupling reduction of 11.64 dB was achieved for the optimized antenna-EBG structure when compare with the case of no EBG.
