We study theoretically driven quantum dynamics in periodic arrays of two-level qubits coupled to the waveguide. We demonstrate that strongly subradiant eigenstates of the master equation for the density matrix emerge under strong coherent driving for arrays with the anti-Bragg periods $d=\lambda /4,3\lambda /4...$. This happens even though are no such eigenstates at low driving powers and is directly manifested by long-living quantum correlations between the qubits.
