小型化窄边单脊波导滤波器设计

通过仿真分析了窄边单脊波导的基本特性，采用所加脊不贯穿整个波导纵向的形式作为单脊波导谐振器，组成直接耦合的切比雪夫带通滤波器，同时输入、输出采用了同轴馈电的方式，与标准波导滤波器相比，可大幅度减小滤波器的体积。最后得到的测试结果表明，该结构能很好地实现波导滤波器的小型化设计。

Design of a Miniaturized Narrow Side Single ridge Waveguide Filter

In this paper, the basic characteristics of the narrow side single ridge waveguide is simulated and analyzed. The directly coupling chebyshev band pass filter is composed of the single ridge waveguide resonators which use the structure with ridge not throughout the waveguide vertical form. Input and output use coaxial feed. Comparing with standard waveguide, it can significantly reduce the filter volume. The final tested results indicate that this structure can achieve good miniaturization design of the waveguide filter.
