Abstract─ A novel quarter-circle defected ground structure shape is introduced in this paper
to design and implement an ultra-wide reject band low-pass filter (LPF). Moreover, an …

A novel wide stopband (WSB) low pass filter based on combination of defected ground
structure (DGS), defected microstrip structure (DMS), and compensated microstrip capacitors …

In this paper, the procedure of attaining a compact microstrip ultra-wideband (UWB) band-
pass filter (BPF) by the use of stub and radial stub loaded resonator and also cross-shaped …

This paper presents new compact microstrip bandpass filters with bandwidth control by
employing DGS resonators. The proposed bandpass filters consists of two coupled DGS …

This work presents a novel frequency miniaturized reconfigurable dual-mode stub-loaded
resonator switchable from bandpass filter to single/double-notched bandnotch filter. The …

This paper deals with a compact Chebyschev 3rd hairpin band pass filter design, using the
Richards-Kuroda transformation method. Afterwards, a combination of slotted ground …

In this paper, a compact via-free low pass filter is designed based on composite right/left
handed (CRLH) concept. The structure uses open ended concept. Rectangular slots are …

A compact ultra-wideband (UWB) band-pass filter (BPF) with band-notch function is
presented in this paper. In the proposed structure defected ground structure (DGS) and four …

A compact planar microstrip bandpass filter with 3.1 GHz? 10.6 GHz bandwidth, below 1 dB
in-band insertion loss, 0.2 ns? 0.6 ns group delay and out-of-band rejection level better than …

The turn ratio, coupling space between sections, and substrate permittivity effects on spilt
ring resonator (SRR) are investigated. The analysis of the presented SRR with respect to the …
