The present work was devoted to theoretical study of capabilities of helical radiators for shaping flat-topped element patterns in planar phased array antennas designed for limited scan applications. The results concerning optimization the radiator parameters and modeling excitation of the central element in a seven-element and nineteen-element arrays with triangular lattice of arrangement of the radiators have shown that the helical radiators allow shaping flat-topped array element radiation of sufficiently high quality corresponding to effective interaction only between adjacent elements. Some new results of concerning the influence of the array edges on the element pattern shape are also have been obtained. Further studies corresponding to the proposed planar arrays can be aimed at its practical realization in prototypes and its modification to obtain patterns of higher quality.
