Compact Dual-Band Bandpass Filter Using U-Shaped Stepped-Impedance Resonators with Parallel Coupled Structures [PDF]
Journal of the Korean Institute of Electromagnetic Engineering and Science, 2018 This paper proposes a dual-band bandpass filter using stepped-impedance resonators (SIRs) with parallel coupled structures. The proposed filter adopts U-shaped SIRs with parallel coupled lines (PCLs) that have interdigital and comb-line shorted ends. The

IET Microwaves, Antennas & Propagation, 2009 The application of step-impedance transmission lines (SITLs) to improving the directivity of parallel-coupled microstrip lines is presented. A simple design procedure for two configurations based on the SITL technique is given. The application of the technique is demonstrated practically with a design at 0.9 GHz on an RF60 substrate.

Compact Stepped Impedance Resonator Bandpass Filter with Tunable Transmission Zeros
, 2017 This paper proposes a compact microstrip bandpass filter (BPF) with tunable transmission zeros, narrow bandwidth and low insertion loss. A λ/4 stepped impedance resonator (SIR) with two additional via holes has been adopted to obtain a compact size and a

NEW WILKINSON POWER DIVIDERS BASED ON COMPACT STEPPED-IMPEDANCE TRANSMISSION LINES AND SHUNT OPEN STUBS [PDF]
Progress In Electromagnetics Research, 2012 This study presents new Wilkinson power dividers using compact stepped-impedance structures and capacitive loads to achieve the required power splitting. This approach can produce additional transmission zeros and efiectively suppress the desired stopbands because shunt open stubs realize capacitive loads.

Radioelectronic and Computer Systems, 2023 The subject matter of the article is the analysis and design of a via free metamaterial antenna based on a composite right/left-handed transmission line (CRLH-TL) structure. The goal is to design a high-gain antenna with dual-band resonance capable of changing its resonance frequency and gain adaptively.
