Portuguese Abstract: In this work, multilayered bismuth titanate ceramic tapes engineered by combining aqueous tape casting and laminating process were produced. The structural and dielectric properties of green and sintered multilayered materials, with 1–5 layers, were explored. Diffraction peaks related to the bismuth titanate phase of structure Bi4Ti3O12 were identified in the precursor powder and the green and the sintered tapes. In addition, a Bi2Ti2O7 structure phase was indexed to the sintered tape. Modifications of the dielectric behavior with the increase in the number of layers composing the samples and with the sintering procedure were observed. Considering the green multilayered BIT ceramics, values between 10 and 14 as a function of the distinct number of layer were found at 1.0 GHz. On the other hand, for the sintered BIT multilayered, values between 2.3 and 8.5 in a wide frequency range were observed, showing a constant behavior as a function of the employed frequency. The results provided interesting insights for tailoring the structural and dielectric properties of the multilayered bismuth titanate ceramic tapes, placing them as a promising candidate fulfilling the needs in a wide variety of technological applications
