Resumen de Analysis and design of a hairpin‐line bandpass filter
Purpose – The purpose of this paper is to present a new way to analyze the hairpin‐line bandpass filter and improve the stopband's attenuation of this filter.
Design/methodology/approach – The even‐odd and open‐short circuit stub mode method is used to analyze the proposed filter and the simulation and optimization are done using the computer‐aided design tools. A design example of a narrowband hairpin‐line filter is provided.
Findings – This improved structure is clearly increasing the stopband's attenuation, at the same time, the bandwidth is narrower.
Originality/value – The paper presents useful analysis of the hairpin‐line bandpass filter; proposes a simple method to analyze this structure, as well as optimization for stopband's attenuation of the hairpin‐line filter.
