In this paper, we present a compact formula for the computation of the array factor (AF) of uniformly excited planar periodic arrays with an arbitrary polygonal contour and a skewed grid. The formulation is based on a simple decomposition of the array as a superposition of infinite angular-sector arrays, whose far field is evaluated in exact closed form. The final result is an exact representation of the AF in terms of contributions from the vertices of the polygonal rim of the array.
