SYSTEMS AND METHODS FOR PERFORMING MULTIPLE INPUT, MULTIPLE OUTPUT (MIMO) OVER-THE-AIR TESTING

摘要

A multiple-input multiple-output (MIMO) over-the-air (OTA) test system and method are provided that enable a device under test (DUT) to be tested that has no antenna connectors for interfacing antenna elements of the DUT with the MIMO OTA test system. The MIMO OTA test system and method can include a lens system that allows the OTA tests to be performed in a radiating near-field zone, thereby allowing a relatively small and less expensive anechoic chamber to be used in the MIMO OTA test system.
