ABSTRACT
We investigate the behaviour of MIMO capacity when the
size of the antenna array is constrained. By increasing the
number of antennas within a small region in space the an-
tenna array becomes dense and spatial correlation inhibits
capacity growth. A theoretically derived antenna saturation
point is shown to exist for dense m a y MIMO systems, at
which there is no capacity growth with increasing antenna
numbers. We show this saturation point increases linearly
with the radius of the region containing the antenna array
and,is independent of the number of antennas.
