Indoor MIMO Measurements Using Polarization at the Mobile

Indoor multiple-inputmultiple-output (MIMO) channel measurements undertaken with spatially separated dipoles are compared with crossed dipoles at 2.4 GHz. This essentially analyses how polarization can be exploited at the mobile using practical antennas where polarization diversity is an inherent feature within an angular diversity system. Results are encouragingly comparable between the two scenarios in terms of capacity and diversity order, which indicates that polarization could be exploited within an angular based MIMO antennas that are more compact than spatially separated antennas.
