The paper focuses on the phase synthesis of one-dimensionally expanded phased array beams. In the study we used the fan partial diagram method. By this method and applying the known amplitude distribution in the aperture and the desired beam shape, we were able to unambiguously determine the desired phase distribution by means of simple calculations. The method is applicable for a phased antenna array and an active phased antenna array with linear and flat apertures. The study is the first to discuss the scaling properties of expanded beams, which allow one to obtain many synthesis options from only one option by multiplying the phase distribution by the scaling factor. Four important properties of scaling are formulated and proved, which must be taken into account when scaling. The paper gives the results of mathematical simulation and experimental measurements, proving the efficiency of the method
