Over-the-Air Test Fixture using Antenna Array

Abstract:

Various embodiments are presented of a system and method for testing (e.g., rapidly and cheaply) devices with antennas configured for radio frequency (RF) and/or millimeter wave (mmW) transmission and/or reception. A device to be tested (e.g., the device under test (DUT)) may be mounted to an interface in a measurement fixture (e.g., a socket, anechoic chamber, etc.). Power and data connections of the DUT may be tested over the interface, which may also provide connections for input/output signals, power, and control and may also provide positioning. RF characteristics (e.g., including transmission, reception, and/or beamforming) of the DUT may be tested over-the-air using an array of antennas or probes.
