Abstract: In this paper, the excited states of the ϕ meson, especially containing the newly observed X(2000) with I(JP)=0(1) by the BESIII Collaboration, is studied. In addition, Y(2175) as a ϕ meson excited state is investigated. The mass spectrum and strong decay behaviors of ϕ meson excited states are analyzed, which indicates that X(2000) and Y(2175) are the candidates of ϕ(3S) and ϕ(2D) states with I(JP)=0(1), respectively. In addition, ϕ(1D) and ϕ(4S) are predicted to have the mass of 1.87 and 2.5 GeV and width of 440 and 940 MeV, respectively.
