In this paper we calculated the masses of S-wave mesons, pseudoscalar and vector decay constants of bottomonium based on the relativistic harmonic confinement model for quarks and antiquarks. The quark potential model used for investigation contains the scalar plus vector harmonic potential interaction, the residual two-body coulomb interaction and the spin dependent interaction. The spin-spin interactions are perturbatively incorporated with the confinement energy to get the respective meson masses. Here, we have also calculated the decay properties of ground state bottomonium. The results are being compared with values obtained from other theoretical models and experimental values.
