Abstract

The sixth-generation communication system (6G) is the next-generation communication system and is expected to be operational in 2030. The following areas will use 6G: the frequency band employed in 6G is expected to be 100 GHz or higher, necessitating additional reduction of the dielectric constant and dielectric loss in the substrate material. In this study, we examined the effects of compounding various phases of alumina with different shapes and crystal phases on the dielectric constant and dielectric loss of cyclo-olefin polymer (COP) compounds. It was confirmed that the smaller the particle size, the higher the effect on the dielectric loss. The dielectric loss decreased from 1.6 × 10 of COP to 1.2 × 10 when the smallest filler was added at 30 wt %.

摘要

第六代通信系统（6G）是下一代通信系统，预计将于2030年投入使用。以下领域将使用6G：6G所采用的频段预计为100GHz或更高，这就需要进一步降低衬底材料的介电常数和介电损耗。在本研究中，我们研究了将不同形状和晶相的各种氧化铝相复合对环烯烃聚合物（COP）化合物的介电常数和介电损耗的影响。结果证实，粒径越小，对介电损耗的影响越大。当以30wt%添加最小填料时，COP的介电损耗从1.6×10降低到1.2×10。
