In this paper, band structure of two-dimensional magnotic crystal composed of elliptic rods triangularly arranged is calculated by using the plane-wave expansion method. The results show that under the condition of the same filling ratio, the width and central frequency of band gap obviously change with the ratio between two radii of ellipse, and that elliptic cylinder scattering body can open the lower frequency band gap or widen the low frequency band gap.
