The antenna-channel effects on multiple-input–multiple-output (MIMO) throughput are characterized in terms of spatial multiplexing (SM) efficiency. In order to show the antenna effects explicitly, the SM efficiency of an MIMO system (with imperfect transmit antennas) is derived analytically at high signal-to-noise ratio (SNR) regime. It is shown that correlation and power imbalance affect the throughput...
The purpose of the present paper is to investigate the MIMO performance of the L-band multi-port Eleven antenna. Both a single- and dual-polarized lab model are investigated, both having 4 ports per polarization. The 4 ports per polarization are normally combined in a 180 deg hybrid to produce sum and difference patterns, but we investigate them here as individual ports in an antenna for a MIMO system...
