It has been widely known that experimental results show that multipath components seem to arrive at the receiver in concentrated groups. These groups of multipath components, or clusters, are usually a result of scattering from large physical structures. Their impact on the capacity of Multiple-Input Multiple-Output (MIMO) systems has been widely studied. However, their impact on the spherical vector waves (svw) expansion of the propagation channel has not yet been addressed in the literature. As we have recently shown, a svw expansion provides a compact and straightforward representation of both antennas and channels. This can potentially facilitate designing antennas tailored to take advantage of the spatial and polarimetric characteristics of the propagation environment, which is essential to the deployment of efficient wireless networks. In this paper, we therefore study the impact of clustering on the first and second order statistics of the multimode expansion coefficients. We adopt the simulation approach to exemplify our results and provide numerical examples.
