ABSTRACT:
Device, system, and method of phased-array calibration. In some demonstrative embodiments, a wireless communication device may include an array of antenna elements; a calibration element located at a predefined location relative to the antenna elements; and an antenna controller capable of calibrating at least one beam forming weight of at least one antenna element of the array of antenna elements based on a detected phase of a calibration signal transmitted via one of the calibration element and the antenna element and received via another of the calibration element and the antenna element. Other embodiments are described and claimed.
