摘要

为了满足射频/微波系统,特别是无线通信系统的严格要求,对传统切比雪夫滤波器以外的先进射频/微波滤波器的需求越来越大。本文将采用基于波概念的迭代方法,结合方法多尺度的模块,对级联四重(CQ)滤波器进行分析。该方法的新颖之处在于用所选粗网格的等效表面阻抗代替粗网格。该方法以较低的计算资源提供了较高的空间分辨率。结果表明,该方法是有效的。

Analysis of microstrip cascaded quadruplet filters by a multi-scale wave concept iterative procedure (M.WCIP)
There have been increasing demands for advanced RF/Microwave filters other than conventional Chebyshev filters in order to meet stringent requirements from RF/Microwave systems, particularly from wireless communications systems. In this paper, we will analysis the cascaded quadruplet (CQ) filters by an iterative method based on the wave concept, combined with the module of the approach multi-scale. The novelty of this method consists in substituting selected coarse meshes by their equivalent surface impedances. This approach offers high spatial resolution with low computing resources. The results are presented and analyzed to demonstrate its efficiency.
