摘要: 根据5G毫米波N258频段应用设计一种微带缝隙耦合天线。天线基于LTCC(Low Temperature Co-fired Ceramic)技术,选用的生瓷带为Ferro A6M。 针对微带天线带宽窄的问题分析其原因并指出存在的不足;创新性地提出一种结合LTCC工艺的耦合柱、耦合片谐振结构,对谐振结构做理论分析并给出仿真结果,该谐振结构在不增加天线尺寸的情况下带宽从4.3%提高至13.4%。该结构为天线组阵提供了一种新的单元形式,可应用于5G毫米波通信系统。

Abstract: A Microstrip slot coupling antenna based on 5G millimeter wave N258 band application is designed. The antenna is based on LTCC (Low Temperature Co-fired Ceramic) technology, and the selected ceramic tape is Ferro A6M. Analyze the reasons for the narrow bandwidth of the microstrip antenna and point out the shortcomings. Innovatively propose a coupling hole and patch combined with LTCC process. Theoretical analysis of the resonant structure and simulation results are present, the bandwidth of the resonant structure is increased from 4.3% to 13.4% without increasing the size of the antenna. A new antenna unit form for array is provided, and can be applied to 5G millimeter wave communication.

Key words: antenna, slot coupling, low temperature co-fired ceramic, resonant structure
