A phased array antenna isan array antenna whose single radiators can be fed with different phase shifts. As a result, the common antenna pattern can be steered electronically. The electronic steering is much more flexible and requires less maintenance than the mechanical steering of the antenna. Visa mer The principle of this antenna is based on the effect of interference, i.e. a phase-dependent superposition of two or (usually) several radiation sources. It can be observed that in-phase signals (same color in Figure 1) … Visa mer How large must be the phase shift x = Δφfrom one radiator to the next radiator to achieve a desired deflection angle? A linear arrangement of isotropic single radiators is … Visa mer Note: The limitation of the scanning range can be overcome with a three-dimensional radiator distribution. This arrangement of the radiators got the … Visa mer These phased array antennas consist of lines, which are commonly controlled by a single phase shifter.
