Slots or defects integrated on the ground plane of microwave planar circuits are referred to
as Defected Ground Structure. DGS is adopted as an emerging technique for improving the …

This paper focuses on a tutorial overview of defected ground structure (DGS). The basic
conceptions and transmission characteristics of DGS are introduced and the equivalent …

This paper proposes a bandpass filter design method for suppressing spurious responses in
the stopband by choosing the constitutive resonators with the same fundamental frequency …

Wide-stopband and compact microstrip bandpass filters (BPFs) are proposed using various
dissimilar quarter-wavelength (/spl lambda//4) stepped-impedance resonators (SIRs) for …

In this paper, microstrip coupled-line bandpass filters using a Koch fractal shape are
proposed for the first time. These filters are fabricated on a liquid crystal polymer (LCP) …

A method to design microstrip bandpass filters with ultra-wideband (UWB) performance,
wide stopband, and practical dimensions is presented. According to the proposed method …

In this paper, a new quasi-transverse electromagnetic (TEM) microstrip line, named as
packaged microstrip line, is proposed for microwave and millimeter-wave applications. It is …

The analysis and design of a microstrip bandpass filter featuring an ultrawide stopband are
presented and investigated in this paper. In this filter, single radial stubs are exploited in …

This paper proposes a simple and effective method to designing wide-stopband bandpass
filters and diplexers using uniform impedance resonators. Microstrip terminated parallel …

This paper presents a close but a beginner's perspective and a comprehensive review of
microstrip filters with defected ground structure (DGS). The concept of DGS is inspired by …
