Antenna aperture size reduction using subbeam concept

in order to reduce the antenna size at the base stations. Cell splitting is known in terrestrial systems, but it uses higher crossover levels between the microcells and results in an increase in the antenna aperture. Such microcell zone concept [Lee, 1991] is generally used to increase the cell capacity, and results in a more efficient system. 2.
