In this paper, exact solutions of scattering states of the Klein?Gordon equation with Coulomb potential plus a new ring-shaped potential are studied under the condition that the scalar potential is equal to the vector potential. The normalized wave functions of scattering states on the ``k/2? scale'' and the calculation formula of phase shifts are presented. Analytical properties of the scattering amplitude are discussed.
