Effect of antenna element properties and array orientation on performance of MIMO systems

Abstract

This paper presents a MIMO throughput based assessment of three candidate antenna arrays, each of which was constructed from a different type of antenna element. A model of the MIMO channel resolved in orthogonal polarization planes was employed to apply multipath parameters of the channel to antenna array patterns, in order to predict the antenna-gain inclusive channel response. Based on simulations of the antenna inclusive channel, an analysis of the effect of antenna element properties including directivity, efficiency and polarization on the statistics of the overall MIMO channel response is presented.
