What Does Phased Array Mean?
A phased array, in antenna theory, is an array of antennas in which all of the phases of each signal that feeds each antenna are set in such a way that the effective radiation pattern of the entire array is set toward the desired direction and that the signals emanating toward undesired directions are suppressed. It is a way to direct waves of radiation toward a desired direction.
Techopedia Explains Phased Array
A phased array antenna has multiple radiating elements, each having a phase shifter of its own. The beams are then formed through the shifting of the signal’s phase that is emitted from each radiating element; this serves as constructive interference toward the desired direction for the waves and as destructive interference for undesired directions. The main beam in a phased array antenna always points in the direction of the increased phase shift.
