ABSTRACT Magnetized ferrites are anisotropic materials used in passive non-reciprocal components. One of the main applications of ferrites at microwave frequencies is the isolation effect. In this work, the non-reciprocal propagation in a ferrite coplanar coupler is studied from simulation results. The proposed structure exhibits a low insertion loss less than 1 dB, and return loss better than 20 dB, with significant non-reciprocal behavior for through propagation. The design of the non-reciprocal coplanar coupler, based on a magnetized transversally ferrite as substrate dielectric material, is presented. The numerical study allows to describe the component physical behavior. As results, a miniature coupler at 12.50 GHz with a non-reciprocal effect in direct access is better than 35 dB has been designed and simulated.

基于铁氧体材料的微波非互易共面定向耦合器

摘要 磁化铁氧体是用于无源非互易元件的各向异性材料。铁氧体在微波频率的主要应用之一是隔离效应。在这项工作中，根据仿真结果研究了铁氧体共面耦合器中的非互易传播。所提出的结构表现出低于 1 dB 的低插入损耗和优于 20 dB 的回波损耗，对于直通传播具有显着的非互易行为。介绍了非互易共面耦合器的设计，该耦合器基于磁化的横向铁氧体作为衬底介电材料。数值研究允许描述组件的物理行为。结果，设计并仿真了一个在 12.50 GHz 处具有非互易效应的直接接入的微型耦合器优于 35 dB。
