Abstract :
A Multiband MIMO antenna is proposed with reduction in mutual coupling and Envelope correlation coefficient. In order to increase data rate in 4G wireless technology Multiple Input Multiple Output(MIMO) technology is obtained, but mutual coupling and ECC are drawbacks in this technology. Mutual coupling between two antennas can be reduced to -18.7dB using simple slot structure on the ground surface and Envelope Correlation Coefficient(ECC) can be reduced to 0.29 using scatter elements on sides of antenna. A MIMO antenna having slot structure on the ground surface and scatter elements on the sides of substrate can reduce mutual coupling upto -18.78dB and ECC upto 0.27 simultaneously.
