Modification of the composition by doping is an effective way to develop new substrate materials for 5G/6G communication systems. This paper aims to study the impact of AlF-CaBO doping on dielectric properties at very high frequencies, sintering temperature, microstructure, and feasibility in LTCC/ULTCC (low/ultra-low temperature cofired ceramics) technology of four low dielectric permittivity materials based on CuBO, ZnSiO, LiBO, and LiWO. Sintering behavior, microstructure, elemental and phase composition, and dielectric properties in the terahertz range were characterized using a heating microscope, SEM, EDS, XRD methods, and time domain spectroscopy. The developed ceramics exhibit excellent dielectric behavior at terahertz frequencies and are feasible in ULTCC or LTCC technology. These properties make them good candidates for substrates in 5G/6G communication systems.
通过掺杂来改变成分是开发用于5G/6G通信系统的新型衬底材料的有效方法。本文旨在研究AlF-CaBO掺杂对基于CuBO、ZnSiO、LiBO和LiWO的四种低介电常数材料在甚高频下的介电性能、烧结温度、微观结构以及在低温共烧陶瓷/超低温共烧陶瓷（LTCC/ULTCC）技术中的可行性的影响。使用加热显微镜、扫描电子显微镜（SEM）、能谱仪（EDS）、X射线衍射仪（XRD）方法和时域光谱对烧结行为、微观结构、元素和相组成以及太赫兹范围内的介电性能进行了表征。所开发的陶瓷在太赫兹频率下表现出优异的介电性能，并且在ULTCC或LTCC技术中是可行的。这些特性使其成为5G/6G通信系统中衬底的良好候选材料。
