This paper presents the design of a compact metamaterial-based MIMO antenna for 5.8 GHz WLAN applications. The proposed antenna consists of two rectangular patches placed on a low-cost FR4 substrate. A series of metamaterial absorber unit cells are integrated between the two antenna elements to attain a high isolation level of 50 dB. The total size of the proposed MIMO antenna is only 32 x 60 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> with a mutual coupling level of less than -50 dB, thus making it an ideal candidate for 5.8 GHz WLAN-MIMO applications.
