A new method is developed to optimize base station antennas. The method is based on
comparison of correlation properties of multipath components in antenna elements. Every
antenna element receive different multipath components from signal is sent because of
multipath propagation. These multipath components should be as uncorrelated as possible
for effective detection of these signals. It is possible to compare different antenna
configurations based on correlation properties between multipath components. The
correlation matrix formed by different multipath components can be used of a comparison
criteria for multielement antennas. The more diagonal is correlation matrix the more
optimal is the antenna configuration. A figure of merit is developed for comparison of
diagonality properties of correlation matrices. It obtained statistically significant
sample by taking mean of figure of merits from correlation matrices of sufficient amount
of different channel conditions.
