Abstract
A Multi-Input-Multi-Output (MIMO) system has multiple radiation elements and absorbers disposed on a substrate. The absorbers are positioned about the radiation elements to reduce the interference between the radiation elements. Use of the absorbers permits interference levels comparable to conventional MIMO systems using spatial diversity without requiring the antennas to be separated by at least one-half of the wavelength of the communicated signals. A ground plane on the substrate is also positioned on the substrate to enhance antenna system performance.
