Disclosed is a phased array antenna capable of sufficiently compensating for not only the changes in beam direction but also the changes in beam shape and side lobe level due to temperature and, thereby, insuring the expected MLS (microwave landing system) performance. A phased array antenna has a plurality of radiating elements, a power divider for distributing transmitting power to the radiating elements, and a plurality of phase shifters each being connected between the power divider and respective ones of the radiating elements. Scanning a beam is effected by controlling the amounts of phase shift of the phase shifters. A characteristic compensating apparatus for the antenna according to the invention, comprises a monitor manifold coupled to the array of the radiating elements for combining outputs radiated from the radiating elements and producing the greatest combined output as a monitor output when the antenna has a predetermined scanning angle, phase error calculating apparatus for calculating, when the antenna radiates a scanning beam of the predetermined angle, phase errors between the outputs of the individual radiating elements and the output of the monitor manifold in response to the combined output of the monitor manifold, and phase shift compensating devices for compensating the amounts of phase shift of the individual phase shifters in response to the calculated phase errors.
