Design and preliminary analysis of a pattern reconfigurable terminal MIMO antenna for receiving antenna selection

Abstract

A newly-built broadband MIMO measurement platform in indoor environment is constructed. The platform is designed for measuring the S21 parameter between M transmitters and N receivers (M<;=8, N<;=8), which enables us to analyze the capacity of the radio propagation channel. A pattern reconfigurable antenna for receiving antenna selection at 2.48GHz has been designed and evaluated. Comparisons of MIMO systems employing antennas with different selection schemes are presented. The system performances are discussed in terms of channel capacity.
