On the MIMO Channel Capacity Saturation for Spatially Constrained Multielement Antenna Systems

In MIMO wireless communication systems, when more and more antennas are packed into a limited space, the antenna saturation phenomenon will appear. Moreover, the electromagnetic interactions among antennas will also become stronger and stronger and affect the antenna saturation effect considerably. Despite this, few studies consider these two effects jointly. Here, the effects of antenna saturation and mutual coupling are investigated jointly, thus a more practical result can be obtained
