摘要

高性能微波腔滤波器在卫星和移动通信系统中的应用越来越广泛。今天，矩形外壳的带通同轴腔滤波器通常用于无线基站，因为它体积小，具有独特的特性，包括低成本，宽调谐范围和出色的无杂散性能。对这些滤波器进行严格的电磁分析，并对所涉及的不同耦合结构进行建模，耗费大量的时间和内存。谐振器和耦合结构的精确而简化的参数模型为滤波器的初步设计和优化提供了有效的工具[1]。

Mutual coupling factor of rectangular loops in rectangular coaxial cavities

High performance microwave cavity filters are finding increasing applications in satellite and mobile communication systems. Today band-pass coaxial cavity filters with rectangular enclosures are commonly used in wireless base-stations because of small size and their unique characteristics including low cost, wide tuning range and excellent spurious-free performance. Rigorous electromagnetic analysis of these filters and modeling different coupling structures involved are quite time and memory consuming. Accurate but simplified parametric models for the resonators and coupling structures provide an efficient tool for preliminary design and optimization of the filters [1].
