A Review: Design and Development of Matched Band-Stop Filter using Lumped-Element

This paper presents a review about the design and development of matched band-stop filter using lumped-element. It is a compilation of band-stop filter design using lumped-element in order to investigate the effectiveness of lumped-element. A lumped-element device is a passive device whose size is significantly less than the operating wavelength in any dimension, resulting in minimum phase shift between the input and output connections. Based on the reviews, it can be concluded that lumped-element have the advantage such as smaller in size since no physically long transmission line. Therefore, accurate mutual inductance between two resonators is not required.
