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 28):
A method for testing a millimeter wave radio frequency (RF) signal transceiver under test (DUT) that includes an antenna array under test (AUT), comprising:\n disposing an AUT at an AUT location within an enclosure; receiving, with an antenna array disposed within said enclosure at a predetermined distance from said AUT location, a plurality of AUT electromagnetic waves from said AUT; receiving, with said antenna array, a plurality of electrical modulation signals; providing, with said antenna array, a plurality of scattered electromagnetic waves that includes a plurality of modulated electromagnetic waves related to said plurality of AUT electromagnetic waves and said plurality of electrical modulation signals; converting, with a transducer within said enclosure, said plurality of scattered electromagnetic waves to a plurality of electrical signals; processing said plurality of electrical signals from said transducer to compute an AUT plane wave spectrum function; providing, with said antenna array in an absence of said plurality of electrical modulation signals, a plurality of unscattered electromagnetic waves that includes a plurality of unmodulated electromagnetic waves related to said plurality of AUT electromagnetic waves; and converting, with said transducer within said enclosure, said plurality of unscattered electromagnetic waves to another plurality of electrical signals.
