Phase shifters are used in countless applications, with one of the most popular being phased array antennas. These antennas do not require a gimbal to keep the beam stabilized. Without this technology the antenna and/or satellite would have to physically adjust itself in three dimensions to simply stay on target―which can prove to be a difficult task, especially where some applications require accuracy within a fraction of a degree. Instead, beams are formed by shifting the phase of the signal emitted from each radiating element in the structure. This provides interference to steer the beams in the desired direction.
