Abstract—A novel to two elements compact The MIMO (Multiple Input Multiple Output) of exploitation of the antenna system 5.0 to 8.0 GHz is proposed for wireless applications. The antenna system developed at 7.7 GHz resonance, giving a bandwidth of 25% (based on S11 < -10dB). An effective technique is proposed to reduce the mutual coupling developed in the antenna System by the use of a simple element microstrip patch in between the antennas. By using the proposed method, the mutual coupling is reduced to approximately -35 dB to the resonance frequency and the maintenance of the whole less of mutual coupling -20 dB in the operating band. Also, envelope correlation coefficient (ECC) between the two antennas is calculated.
