纵向磁化铁氧体基片上微带线的特性分析

摘要

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 bet-ter the linearity is ,and greater bandwidth can be achieved .The research can provide theoretical basis for the design of mi -crostrip ferrite derices .%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。
