N2 - A passive repeater (PR), comprising a four-element folded-patch antenna (FPA) array, a planar Yagi-Uda antenna, and a power combiner, was fabricated to experimentally investigate the multiple-input-multiple-output (MIMO) performance in multipath environment. It was found that the PR could realize polarization transition and broad-angle scattering. The received power and the MIMO channel capacity, which reflect MIMO performance, were discussed to demonstrate the effectiveness of the four-unit PR in improving the propagation channel in MIMO communications. It was found that the medians of the received power of Rx1 and Rx2 were improved by about 17 dB as compared to those without the PR. Also, when the received noise level was supposed to be ${-}$120 dBm/Hz, the median of the MIMO channel capacity with the PR was increased by 6.4 bps/Hz as compared to that without the PR.
