Two novel microstrip patch DGS (Defected Ground Structure) based MIMO (Multiple Input Multiple Output) antennas have been proposed and presented in this paper. The objective is to design a DGS based MIMO patch antenna module appropriate to reduce mutual coupling coefficients and enhance wide bandwidth with low loss significance for many wireless device. The presented MIMO antennas have been analysed designed simulated and investigated using EM (Electromagnetic) simulator. They have been fabricated (FR-4 substrate) and their return loss, bandwidth, gain, have been measured. The first MIMO antenna radiates at 5.9GHz and its isolation -17.9dB with overall bandwidth 369MHz. This MIMO antenna has mutual coupling coefficient (MCC) and gain are -23.9dB, 5.69dB respectively and second MIMO antenna radiate at 5.9GHz and its isolation -20.15dB with overall bandwidth 398MHz. This MIMO antenna has MCC and gain are -23.38dB, 4.44dB. Good agreement has been achieved between simulated and measured results. The proposed antennas are compact size wide bandwidth, moderate gain, good efficiency and high port-to-port isolation.
