Study of Various Mutual Coupling Reduction Techniques in MIMO Antennas

Abstract

MIMO antennas are playing crucial role in satisfying high demand of wide bandwidth, high channel capacity and high data rate in wireless communication. MIMO antennas are one of the best solution to solve the problem of multipath propagation. The level of performance of the MIMO antenna is very high and steep if represented graphically but due to the use of many antennas the issue of mutual coupling occurs which deteriorates the MIMO antenna's performance. Here, the various types of monopole, fractal and hybrid antennas which can be chosen to make a MIMO system are discussed.
