Multiple-input-multiple-output (MIMO) technology is widely used in modern wireless communication devices in order to achieve higher channel capacities without additional power and frequency spectrum. A number of closely packed antenna elements are normally required in modern multi-element-antenna (MEA) handsets or wireless routers using MIMO technology. As the distance between the antenna elements decreases, which is particularly common in compact handheld devices, the increased mutual coupling degrades the performance of these schemes [1, 2]. Therefore, the reduction of mutual coupling between closely spaced antenna elements on compact MIMO handheld terminals is an important factor for improving the overall system performance. Recently, defects on the ground plane between the antennas have been proposed for reducing the mutual coupling, such as multiple etched slits [3, 4] and more recently optimized pairs of slits [5].
