Abstract:
A system and method for testing (e.g., rapidly and inexpensively) devices such as integrated circuits (IC) with integrated antennas configured for millimeter wave transmission and/or reception. The method may first perform a calibration operation on a reference device under test (DUT). The calibration operation may determine a set of reference DUT FF base functions and may also generate a set of calibration coefficients. After the calibration step using the reference DUT, the resulting reference DUT FF base functions and the calibration coefficients (or reconstruction matrix) may be used in determining far-field patterns of DUTs based on other field measurements, e.g., measurements taken in the near field of the DUT.
