(a) Top view of 2D periodic planar EBG structures made of patch and two-turn meander lines. (b) Computational setup used to extract the dispersion diagram of the EBG-unit cell in infinite array. The appropriate boundaries are shown in the setup. (c) Irreducible Brillouin zone triangle. (d) Top view of the unit cell.
