## Abstract The authors applied the method of FoldyβLax multiple scattering equations to multiple vias in ball grid arrays and the interior layers of printed circuit boards. The method gives the scattering parameters of the array. The results are verified with Ansoft's HFSS with very little differe

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 view point of capacity is presented.

Contemporary information on the trends and patterns of mortality associated with birth defects and genetic diseases is lacking in the United States. To study these trends and patterns, we used the Multiple-Cause Mortality Files of the National Center for Health Statistics. From 1979 through 1992, 32
