Broadcast phased arrays have fixed radiation patterns and are not 'steered' during operation as are other phased arrays. Phased arrays are used by many AM broadcast radio stations to enhance signal strength and therefore coverage in the city of license, while minimizing interference to other areas. See more In antenna theory, a phased array usually means an electronically scanned array, a computer-controlled array of antennas which creates a beam of radio waves that can be electronically steered to point in different directions … See more Broadcasting In broadcast engineering, the term 'phased array' has a meaning different from its normal meaning, it means an ordinary array antenna, … See more There are two main types of beamformers.
