Abstract

In this paper, a defected ground structure is employed in a transceiver array antenna to reduce coupling between the two antennas. The two arrays for transmitting antenna and receiving antennas are implemented on the same substrate with close separation. The coupling reduction principles for each transceiver MIMO antenna are explained. The MIMO antenna performance was examined using electromagnetic full wave. Results confirm that both coupling reduction reached better than15 dB with very close spacing; 2 mm spacing which is less than 0.05 λ0.
