Abstract:
Systems and methods for detecting faulty elements in an active planar antenna array of an extremely high frequency (EHF) wireless communication device. A planar antenna array having a matrix of dual-polarization modulated scattering probes is disposed within a near-field region of the antenna under test (AUT). Electromagnetic energy received from the AUT is converted to a complex electrical signal that is modulated by an electrical modulation signal and radiated as a scattering signal. The resulting electromagnetic scattering signal, received and converted to an electrical signal by another antenna, is used in a holographic image reconstruction operation via a backward-propagation transformation to reconstruct the signal spectrum radiated from the surface of the AUT. A comparison of this reconstructed signal spectrum with a reference signal spectrum radiated from the surface of a known good antenna array enables detection of faulty antenna elements within the AUT.

Claim (Index 13):
An apparatus including at least a portion of a test system for testing a millimeter wave radio frequency (RF) signal transceiver under test (DUT) that includes an antenna array under test (AUT), comprising:\n an enclosure configured to enclose an AUT disposed at an AUT location within said enclosure; a transducer disposed within said enclosure and configured to convert a plurality of scattered electromagnetic waves to a plurality of electrical signals; an antenna array disposed within said enclosure between said AUT location and said electromagnetic transducer at a predetermined distance from said AUT location, and configured at least in part to\n receive, from said AUT, a plurality of AUT electromagnetic waves, \n receive a plurality of electrical modulation signals, and \n provide, as said plurality of scattered electromagnetic waves, a plurality of modulated electromagnetic waves related to said plurality of AUT electromagnetic waves and said plurality of electrical modulation signals; and \n processing circuitry coupled to said transducer and configured to process said plurality of electrical signals to compute an AUT plane wave spectrum function; wherein\n said transducer is further configured to convert a plurality of received electromagnetic waves to another plurality of electrical signals; and \n said antenna array is disposed within said enclosure between said AUT location and said electromagnetic transducer at said predetermined distance from said AUT location and, in an absence of said plurality of electrical modulation signals, further configured to pass, unscattered, said plurality of AUT electromagnetic waves to said transducer as said plurality of received electromagnetic waves.
