Abstract: We study the effect of dipolar interactions on a magnetic striped monolayer with a microscopic unit cell of square symmetry, and of size $(N_x\times N_y)$ spins. Even if the aspect ratio r=Nx/Ny is very large, an in-plane shape anisotropy is always negligible, except if Ny is fairly small (Ny<40). In-plane domains are not possible, except for values of the dipolar coupling larger than the domain wall energy.
