Abstract: Based on a duality relationship between magnetic and dielectric substrates, the characteristic impedance, propagation content and phase shift characteristic of microstrip line on longitudinally-ferrite substrates are researched. The conclusion can be drawn that they are proportional to bandwidth of microstrip line,  and the higher the frequency is, the better the linearity is, and greater bandwidth can be achieved. The research can provide theoretical basis for the design of microstrip ferrite derices.

摘要:本文基于磁性介质和各向同性介质基片的对偶关系, 研究了纵向磁化铁氧体基片上不同尺寸微带线的特性阻抗、 传播常数和相移特性。 通过分析可以看出: 铁氧体基片上微带线的特性阻抗、 传播常数以及单位长度的相移量与微带线带宽成正比。 并且在更高频段, 各特性线性更好, 带宽更大。 本研究可以很好地为微带铁氧体器件的设计提供理论基础。
