The method of calculation of wire radiators characteristics in the infinite planar phased array with an oblique-angled grid is developed. Each radiator can consist of a set of arbitrarily oriented in space linear wire pieces, including branches, loops, etc. The moment method is applied, and piecewise sine functions are used as basic and weight ones. The closed analytical expressions as double spectral series are received for elements of the mutual impedances matrix. Comparison with results of other authors carried out.
