In this paper, a 60° photonic crystal bending geometry for TM modes of a Kagome lattice is proposed. A two dimensional array of dielectric rods with refractive index of 3.25 is used for this purpose. The proposed bending structure has a tapered topology which increases the transmission pulse. A bandwidth is defined as the region where the transmission ratio is higher than 0.8 or equally 1dB and equals to 4nm where the central wavelength is at 1330nm. The simulation is performed with the help of two numerical algorithms which are called FDTD and PWE.
