Comparative analysis of the subarray radiation patterns and element use factor in the limited-scan phased arrays with interwoven and chessboard feeding networks is carried out. It is shown that though the attenuators in the interwoven networks can provide a wider sector of scanning at low level of the array factor grating lobes, their use results in a considerably greater number of the controlled elements necessary for providing specified gain in a specified sector of scan in comparison both with the case of the chessboard networks and with the case of the interwoven networks without the attenuators.
