摘要

提出了一种新的椭圆函数滤波器响应的物理实现方法，以达到体积小、带宽宽、无杂散阻带宽和高选择性的目的。采用严格的模式匹配分析了典型脊波导滤波器的结构。为了验证这一概念，按照系统的程序设计了一个实现典型四腔椭圆滤波器耦合矩阵的原型。采用近似综合的方法得到滤波器的初始尺寸，并通过最后的全波优化得到期望的最优响应。用其他数值方法对结果进行了验证，并将制作样机进行测试。

Full-wave design of canonical ridge waveguide filters

A new physical realization of an elliptic function filter response is proposed for achieving compact size, wide bandwidth, wide spurious free stop band and high selectivity performance. The canonical ridge waveguide filter configuration is analyzed using rigorous mode-matching. To validate the concept, a prototype that realizes the coupling matrix of a canonical four cavity elliptic filter is designed following a systematic procedure. Approximate synthesis is used to obtain initial dimensions of the filter and the desired optimum response is obtained by means of a final full-wave optimization. The results are verified with other numerical method and a prototype will be built for testing.
