Abstract
A system for testing a device-under-test (DUT) over-the air (OTA) includes a probe antenna, an azimuth positioner, a linear positioner and a roll positioner. The probe antenna measures radiated fields from the DUT and emits radiated fields to the DUT by illuminating active antenna elements of the DUT. The azimuth positioner rotates the DUT in a first plane about an azimuth axis. The linear positioner drives the DUT linearly along a first Y-axis in a second plane orthogonal to the first plane and drives the DUT linearly along a second X-axis perpendicular to the first Y-axis in the second plane to stay within a quiet zone of the system. The roll positioner is provided between the second plane and the azimuth positioner and is configured to rotate the DUT about a roll axis orthogonal to the azimuth axis.
