This paper presents effect of delay waves on MIMO over-the-air (OTA) throughput of a handset MIMO array using a spatial fading emulator. The emulator has a number of antenna probes located on a circle around a handset under test to representing a multipath radio environment applicable to the OTA evaluation for a handset MIMO antenna. The MIMO OTA tests with and without delay waves, which have a...
