Abstract
Wide band Multiple-Input Multiple-Output (MIMO) antenna arrays include elements that taper from small ends located proximate to ground planes to larger ends which may be extended with vertical walls. Different shapes of tapered elements which exhibit different directivity patterns may be used in the same array and/or elements may be oriented differently such that their directivity patters peak in different directions. Each element is provided with symmetrically or asymmetrically located ground shunted conductors which serve to increase non-uniformity in the azimuthal directivity patterns. The ground shunt conductors are strategically placed to reduce element intercoupling which foster improved MIMO system performance.
