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 25):
