    Most phased arrays are designed using infinite array theory. However, when finiteness is included, edge effects perturb their behaviour. Truncation effects can become dominant especially in broadband arrays, which are characterized by strong mutual coupling between neighbouring elements. Although finite array simulations would predict these effects, they are computationally very expensive. In this paper, an accurate and analytical procedure to assess edge effects in finite connected arrays is presented. The derivation of an approximated expression of the electric current distribution on the array provides physical insights in the induced dominant edge wave mechanism. Some useful rules for the design of finite connected arrays are also presented.
