Phase shifters are shared by many antenna elements, since it is not practical to have a separate fiber routed to each antenna. The phase shifts that are presented to the individual elements are therefore correlated random variables. The authors examinine the consequences of this correlation on the beam shape. They study two extreme cases for a linear array: an uncorrelated architecture and a fully correlated architecture. They examine the gain, direction, beamwidth, and main-to-first lobe ratio for both cases, as a function of the number of array elements.
