Tri-layered structural Zn 0.997 Cu 0.003 ZrNb 2 O 8 -TiO 2 +ZnO/TiO 2 +CuO/TiO 2 -Zn 0.997 Cu 0.003 ZrNb 2 O 8 ceramics with different mass fractions of TiO 2 +ZnO/TiO 2 +CuO/TiO 2 were successfully prepared. The advantages of the multilayered design were completely demonstrated, and the microwave dielectric characteristics were modified by the components of each dielectric layer. In comparison to the random distribution-type, Zn 0.997 Cu 0.003 ZrNb 2 O 8 @TiO 2 +ZnO, this tri-layered construction could increase the Q × f value by approximately 100%. Meanwhile, based on the electronic compensation mechanisms, the Q × f value of the tri-layered structural ceramics with TiO 2 -doped interlayer can be increased by nearly 20% compared with that of the pure TiO 2 interlayer. The Zn 0.997 Cu 0.003 ZrNb 2 O 8 -TiO 2 +ZnO-Zn 0.997 Cu 0.003 ZrNb 2 O 8 tri-layered ceramic exhibited excellent dielectric characteristics (𝜀 𝑟 = 33.75, Q × f = 59 000 GHz, and 𝜏 𝑓 = +2.27 ppm/ • C) with 0.05 wt% TiO 2 +ZnO sintered at 1240 • C for 6 h, and the integrated optimization of microwave dielectric characteristics was achieved. This article provides a strategy for the synthesis of high-performance microwave dielectric components for application in 5G/6G wireless communication technologies.
