Abstract

In this paper, we study the effect of antenna directivity on multi-input-multi-output (MIMO) antenna selection. A 4 orthogonal pattern antenna array platform at the receiver side associated with an antenna selection mechanism is used in this study. The performance of the proposed method is evaluated for two cases where the antenna selection switches are located either after or before Low Noise Amplifiers (LNA), on a MIMO system under the diversity transmission. The results show how the antenna directivity and switch loss can affect the overall MIMO system performance.
