In this paper, we investigated the spectroscopy of heavy tetraquarks through a relativistic diquark-antidiquark model. To this aim, the two-bosonic Klein-Gordon equation in the presence of vector Coulombic-like and scalar linear potentials is solved numerically to calculate the average masses of heavy tetraquarks in the ground and excited states. Incorporating the spin-dependent interactions removes the degeneracy of the states and results in the exact masses of charm- and bottom-containing tetraquarks and throughly the predictions for the masses of bottom and charm tetraquark candidates are given.
