It is assumed that the vector meson φ is a resonance which is formed of the KK scattering by exchange of ρ, ω and φ itself. The method of N/D of the double dispersion relation is used and the experimental values of the masses are known for the ρ, ω and exchanged φ. The partial wave amplitude of the KK scattering is given approximately. When it is required for the partial wave amplitude to give in turn the correct position and width of the resonance, the relations for the coupling constants fφKK2,fωKK2 and fρKK2 are found and the values available for them are determined.
