Now a day’s the MIMO (Multiple Input Multiple Output) antennas with arrays became hot topic of study. The most common necessity of today’s wireless communication system is high data rate along with neutralization of the effect of fading when signal propagates through various surroundings, thus MIMO antenna system is turn out to be solitary solutions of this. For augmentation of range and dependability of the wireless system mainly used technology is MIMO antenna system. The main problem with MIMO antenna is strong mutual coupling stuck between antenna elements due to which there is signal interference between them and hence there is significant decrement in antenna’s performance by the higher value of mutual coupling. Therefore the value of mutual coupling should be low as much as possible. This paper shows different procedure projected for reducing the value of mutual coupling among antenna elements.
