A recent method has been proposed for determining the optimal radiation characteristics of antennas that maximize the diversity gain for a given antenna aperture and power angular spectrum of the field. Since this approach results in antennas whose current distributions overlap in the aperture, however, the resulting designs are impractical. This paper proposes several methods which construct the radiation characteristics for non-overlapping currents. Computational results show that the resulting diversity performance of the designed antennas is good but sub-optimal.
