Abstract
A three-dimensional spatial division antenna system is utilized for a frequency band divided into a predetermined number of channels, adjacent channels in the frequency band having a predetermined bandwidth overlap. A plurality of antennas is distributed in a three-dimensional facetted configuration. A plurality of polarization planes is respectively associated with the plurality of antennas, each of the polarization planes being oriented at substantially 90 degrees relative all of the other polarization planes. Sets of non-overlapping channels of the predetermined number of channels are assigned to the polarization planes.
