Reconfigurable OTA chamber for MIMO wireless device testing

Over-the-air (OTA) testing of wireless devices is accomplished typically either in an expensive multi-antenna OTA chamber that offers high multipath control or a low-cost mode-stirred reverberation chamber that offers limited multipath control. We propose a reconfigurable OTA chamber that offers a high level of multipath control at a low cost. We use finite-difference time-domain simulations and measurements to evaluate the achievable fading distribution and power angular spectrum at the device under test.
