摘要

本文提出了一种允许实现传输零点的行波环路定向滤波器的新设计。为了将传输零点引入滤波器的带通支路，采用传输线段将两个环路级联。对电路进行了理论分析，给出了与回路连接段的电长度相关的出现传输零的行为。通过一个典型级联单环定向滤波器的设计和测量，验证了所提出方法的性能，该滤波器具有两个对称放置的传输零点，覆盖ISM 2.4 GHz频段。所得结果证明了该方法的有效性。

Cascaded loops directional filter with transmission zeroes for multiplexing applications

In this paper, a new design of a traveling wave loop directional filter allowing for realization of transmission zeroes has been proposed. In order to introduce transmission zeroes to bandpass branch of the filter, two loops have been cascaded using transmission line sections. Theoretical analysis of the circuit has been provided giving the insight into behavior of the appearing transmission zeroes related to electrical lengths of the loops' connecting segment. Performance of the presented approach has been verified by the design and measurements of an exemplary cascaded single-loops directional filter with two symmetrically placed transmission zeroes covering ISM 2.4 GHz band. The obtained results prove the usefulness of the presented approach.
