Diversity mechanisms of MIMO antennas with six degrees-of-freedom

Summary, in Swedish
Abstract in Undetermined
In this paper, we investigate the roles of different diversity mechanisms in two recently proposed six-port MIMO antennas using the effective degree-of-freedom concept. In particular, we confirm that angle and polarization diversities are indeed the dominant diversity mechanisms for the compact antenna that is designed to replicate the characteristics of the ideal co-located six-port antenna. On the other hand, a physically larger reference antenna is found to offer substantial space diversity, in addition to angle and polarization diversities, allowing it to outperform the compact antenna in propagation scenarios with narrow angular spreads.
