Abstract

There are several numerical methods for designing and analyzing new high-frequency micro- and millimeter- wave passive components in waveguide technology. Computer Aided Design (CAD) tools commonly used in the industry are based on different techniques such as Finite Element, Finite Differences, Moments and Mode-Matching methods. The aim of this paper is to compare the processing performance required by some of the commercially available CAD tools against an in-house software tool based on the Mode-Matching method, for the design of different structures of directional couplers with large number of ports. The results obtained show good agreement amongst the methods, the self-developed software tool based on the Mode- Matching method required less processing time than commercial available software indicating therefore that this method may be a good choice for complementing the analysis since it will also produce good results for designing and validating specific geometries of power distribution network devices with large number of ports.

大端口配电网数值分析方法的比较

在波导技术中，有几种设计和分析新型高频微毫米波无源元件的数值方法。工业中常用的计算机辅助设计(CAD)工具基于不同的技术，如有限元、有限差分、矩和模式匹配方法。本文的目的是比较一些商用CAD工具和基于模式匹配方法的内部软件工具对具有大量端口的不同结构的定向耦合器的设计所要求的处理性能。所获得的结果显示了方法之间的良好一致性，基于模式匹配方法的自行开发的软件工具比商用软件所需的处理时间更少，这表明该方法可能是补充分析的好选择，因为它也将为设计和验证具有大量端口的配电网络设备的特定几何形状产生良好的结果。
