Performance analysis of a reconfigurable antenna array in WLAN channel models

Abstract

This paper presents a performance evaluation of a pattern reconfigurable antenna array in a clustered MIMO channel model. Using the IEEE 802.11 TGn and TGac standard channel models, the effect of pattern diversity is investigated in both single-user and multi-user MIMO systems. The numerical results show that the additional degrees of freedom provided by a pattern reconfigurable array can mitigate the effects of co-channel interference and provide a significant gain in system capacity.
