Mutual coupling reduction in two elements UWB notch antenna system

In this paper, a two elements UWB (3.1 GHz-10.6 GHz) MIMO antenna is presented. A notch frequency at 5.8 GHz is interpolated within the UWB spectrum by using a dual of electromagnetic bandgap cells coupled to the antenna feeding line. By introducing a system of electromagnetic bandgap cells between the two antennas elements, the achieved results demonstrate nearly below -10 dB reflection coefficient over the spectrum and -1 dB at the notch frequency. Also, deposition between the two antennas is achieved to exceed 20 dB. The obtained results are simulated using full wave simulations.
