Abstract

This paper presents an implemented calculator tool for the design of Edge/ Parallel Coupled Microstrip Band Pass Filters (PCMBPF) that makes use of the MATLAB software. This calculator allows estimating both the parameters required for the design of the PCMBPF and the electrical response which is obtained by means of the equivalent circuit of this type of filters. Based on the transmission line theory approach (TLTA), the calculator herein proposed is a good solution to simply obtain the design parameters of this type of filters given that all formulas required for the PCMBPF design are programmed using close-form mathematic expressions and the coupling matrix concept. In order to validate our calculator performance, we implemented the proposed filter in a commercial electromagnetic simulator CST MWs that considers a set of electromagnetic effects, and accurately determine the final filter design. Secondly, we compared these simulation outcomes with the measurement results, achieving a reasonable agreement.

边缘与平行耦合微带带通滤波器计算器的研制

本文介绍了一种利用MATLAB软件实现的边沿/并联耦合微带带通滤波器(PCMBPF)设计计算工具。这个计算器可以估计PCMBPF设计所需的参数和通过这种滤波器等效电路获得的电响应。本文提出的基于传输线理论方法(TLTA)的计算器是一种很好的解决方案，因为PCMBPF设计所需的所有公式都是使用封闭形式的数学表达式和耦合矩阵概念编写的，可以简单地获得这种滤波器的设计参数。为了验证我们的计算器性能，我们在商用电磁模拟器CST MWs中实现了所提出的滤波器，该模拟器考虑了一组电磁效应，并准确确定了最终的滤波器设计。其次，我们将这些仿真结果与测量结果进行了比较，得到了合理的一致。
