| 摘 要： | 通过引入弯折型马刺线，提出了一种新型微带双模滤波器。该结构降低了传统微带双模滤波器的耦合损耗，减小了滤波器尺寸，并具有良好的可调节带通特性。给出了该滤波器的模式激励与耦合工作机理的物理解释，并提出结合RBF神经网络方法，外推滤波器结构参数的设计方法。该滤波器实验结果与预测结果吻合良好。

| Abstract: | A novel dual-mode microstrip filter by mounting a pair of meandered spurline on a traditional patch is given in this paper.Compared with the conventional dual-mode one,the proposed filter configuration has advantages of compact size,low-insertion-loss and adjustable pass band characteristics.Moreover,the excitation mechanism of dual-mode filter is presented and a CAD method based on RBF neural network is applied to optimize the filter design.Finally,a good agreement is obtained between measured and predicte... |
