We study sharp frame bounds of Gabor systems over rectangular lattices for different windows. In some cases we obtain optimality results for the square lattice, while in other cases the lattices optimizing the frame bounds and the condition number are different. Also, in some cases optimal lattices do not exist at all and a degenerated system is optimal.Comment: 55 pages, 17 figures, 51 reference
