This paper considers specific features of the phase synthesis of expanded sector beams formed by phased antenna arrays by the method of fan partial diagrams. Partial radiation patterns are formed by pairs of adjacent emitters. The synthesis results have the property of scaling, which allows many expansion options to be obtained on the basis of one expansion option. This is achieved by multiplying the phase shift values of the signals from all emitters by the same value. It is shown that, when the beam expands along the sum channel, a radiation pattern with an extended angular distance between the maxima is formed in the difference channel. An analysis of the initial sections of the difference radiation patterns in the formation of expanded beams of the sum radiation pattern was conducted. The behaviour of the generalized characteristics of expanded beams across the range of expansion coefficients was analysed. The conclusion was made about the possibility of timely and predictable control of the width of the difference radiation pattern of a phased antenna array
