To realized the uniform phase distribution on the aperture plane, the resonant-conductor shape of each element with phase property depending on both the frequency and the position on the reflectarray plane is individually designed by the GA-optimized method. By using the optimized elements, two kinds of the reflectarray for a linearly polarized wave and with conversion into a circularly-polarized wave are constructed, and the beam shift characteristics are investigate numerically and
