Different channel models capacity calcualtions for different UWB MIMO antenna systems

This paper presents capacity calculations for different MIMO antenna systems. The capacity calculations are applied for Kronecker model, and one ring model. Three configurations of MIMO antenna system are presented which conduct different mutual coupling due to different spacing and orientation of its antenna elements. Each configuration has four UWB antenna elements. Matlab codes are used to depict the capacities versus the SNR and the frequency for the three configurations. The results discuss the effect of the mutual coupling and the spatial correlation on the capacity of the system using the mentioned models. On the other hand, a selected antenna configuration shows fair agreement between the measured and simulated return loss.
