Abstract

Standardization work for MIMO OTA testing methods
is currently ongoing, where a multi-probe anechoic chamber
based solution is an important candidate. In this paper, the
probes located on an OTA ring are used to synthesize a plane
wave field in the center of the OTA ring, and the EM field for
each probe is obtained using FDTD simulation. This paper
investigates the extent to which we can control the field structure
inside the test zone where the device under test is located. The
focus is on performance deterioration introduced by probe
placement error including OTA probe orientation error and
location mismatch, which are general non-idealities in practical
MIMO OTA test systems.
