摘要

已经测量了一些短路的串联插脚。基于这些测量得出的参数，构建了一系列低通滤波器，它们在截止频率上表现出极好的一致性，但在其阻带中表现出意想不到的行为。在不遵守这些特性的情况下，给出了具有理想存根的滤波器的模拟结果。提出这些特性是由于存根之间的共振耦合造成的，并提出了支持这一理论的证据。

Lowpass filters using series stubs

A number of short circuited series stubs have been measured. Based on parameters derived from these measurements, a range of lowpass filters have been constructed which show excellent agreement in cut-off frequencies but unexpected behaviour in their stopbands. Simulated results for filters with ideal stubs are presented with no observance of these peculiarities. It is proposed that these peculiarities are due to resonant coupling between the stubs and evidence to support this theory is presented.
