The realization and analysis of pattern/polarization diversity in multiple input multiple output array

Abstract

This article proposes the pattern/polarization diversity array for multiple input multiple output applications by applying vertical and horizontal excitation. We show that pattern and polarization of antenna are changed due to vertical feeding. Then, we attempt to realize the two antenna diversity array by using different feeding method. As a result, the correlation factors with respect to the pattern and polarization diversity are investigated. Finally, the analysis of the diversity system in the viewpoint of capacity is presented.
