Multiple Input Multiple Output (MIMO) systems use multiple antennas at both the transmitter and receiver to improve quality and data rate mobile communication. In recent year, various antennas working on dual or multi bands have been developed. The increasing mutual coupling is one of the negative effect due to the addition of antenna element in MIMO system. This paper present a low mutual coupling dualband MIMO 2x2 antenna. The proposed MIMO antenna is able to work in dual frequency at 1.8GHz and 2.35GHz. To obtain the optimum design, the charactertistic of proposed antenna are numerically investigated through the phisical parameters of antenna. By parasitic layer with air gap, mutual coupling can be decreased until 50% and gain of the proposed antennacan be improved until 50%. The obtained results show that proposed antenna has a compact size and a bandwidth of 100 MHz.which is suitable for LTE application.
