摘要

毫米波技术在材料、化学、通信和生命科学等领域具有巨大的应用潜力。近年来，高介电常数和低损耗毫米波器件的发展得到了推动。本文研究了0.95 mgtio3 -0.05 5catio3和TiO2陶瓷体系。讨论了烧结工艺、微观结构对太赫兹性能的影响。0.95 mgtio3 -0.05 5catio3陶瓷具有18的介电常数和1.9 × 10−3的超低损耗;TiO2陶瓷具有102的高介电常数和4.2×10−3的超低损耗。

High Permittivity and Low-Loss Millimeter-wave Dielectric Ceramics

Millimeter (mm)-wave technology has great potential in applications of material, chemical, communication and life sciences. The development of high permittivity and low loss mm-wave devices has been promoted in recent years to boost the technologies. Here, the 0.95MgTiO3-0.05CaTiO3 and TiO2 ceramic systems have been investigated. The influence of sintering process, microstructure has been discussed to optimize the THz performance. The 0.95MgTiO3-0.05CaTiO3 ceramics can possess permittivity of 18 and ultra-low loss of 1.9 × 10⁻³; the TiO2 ceramics show high permittivity of 102 and ultra-low loss of 4.2×10⁻³.
