Abstract. A new weight function (WF) was proposed. It is based on the optimal Dolph-Chebyshev WF and extends its capabilities to obtain the required characteristics of the radiation patterns (RP) of equidistant antenna arrays (AA). It provides a controlled reduction of distant side lobe of RP and of current of elements at the edge of ÀÀ, increasing the level of the signal emitted by an active AA with a limited level of signals of its elements; it allows to control the speed of decreasing of the hither side lobes and the position of zeros of envelope of the side-lobe. The new WF preserves properties of original WF: regulation of level of side lobes and proximity to a minimum of width of the main lobe of RP. It can be used for digital and analog signal filtering by transversal (nonrecursive) filters, discrete Fourier analysis, increasing the signal level, decreasing diffraction distortion of interdigital transducer (IDT) of narrowband surface acoustic wave (SAW) filter.

Keywords: antenna array, radiation pattern, weight function, Dolph-Chebyshev function.
