Fifth-generation mobile communication systems provide a huge market for microwave dielectric materials, especially in the manufacture of resonators, filters, substrates, and antennas. Herein, an excellent performance ceramic x(NaBi)0.5MoO4–(1–x)MoO3 (0.2 ≤ x 0.9, abbreviated as xNBM–(1–x)MO sintered below 660 °C with two coexisting phases is prepared via solid solution reaction. With increasing value, sintering temperature rises from 600 to 640 °C. The properties have series changes...
Indialite/cordierite glass-ceramics demonstrate excellent microwave dielectric properties such as a low constant of 4.7 and an extremely high quality factor Qf more than 200 × 103 GHz when crystallized at 1300°C/20 h, which are essential criteria for application to 5G/6G mobile communication systems. The applied resonators, low-temperature co-fired ceramic (LTCC) substrates, direct casting glass substrates reviewed in this paper. fabricated by the crystallization with cordierite composition...
High-temperature cofired ceramics and low-temperature are important technologies in the fabrication of multilayer ceramic substrates for discrete devices, electronics packages, telecommunications. However, there is a place need materials with lower temperatures to decrease associated energy consumption.
