Design of Lowpass Filter Using Complementary Open-Loop Resonators

2008 China-Japan Joint Microwave Conference, 2008
In this paper, a new methodology for the design of compact planar lowpass filters in microstrip technology is proposed. This is based on cascading filter stages consisting of the combination of complementary open-loop resonators (COLR), proposed by the authors for the first time, and open stubs.

Microstrip low‐pass filter using open loop resonators

Microwave and Optical Technology Letters, 2008
AbstractA compact open loop resonator microstrip low pass filter is modeled. To optimize the performances of the filter, electromagnetic simulation is used to tune the dimensions of proposed prototype. Cascading of open loop resonator provides a very sharp cut off and wide stop band with minimum insertion loss.

Open loop synchronous rectifier driver for LLC resonant converter

2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2013
Synchronous rectifier (SR) is widely used in LLC resonant converter to reduce the conduction loss. Due to different operation modes, the SR control is complicated and increases system cost. In this paper, based on the observation on LLC diode conduction time, an open-loop fixed-on-time SR driving method is proposed.

Improvement of microstrip open loop resonator filter using aperture

2002 IEEE MTT-S International Microwave Symposium Digest (Cat. No.02CH37278), 2003
Apertures has been employed on the ground plane in the open loop resonator filter. The bandwidth has been widen maximally 40% and the passband ripple has been flatten compared with the conventional open loop resonator filter. The coupling spacing between loops has been widened to easily implement filter.

A dual-band bandpass filter using open-loop resonator

Proceedings of 2012 5th Global Symposium on Millimeter-Waves, 2012
This paper presents a way of dual-band bandpass microstrip filter design based on open-loop resonator. The asymmetric structure gets better out-of-band rejection comparing to the symmetric structure for the two open-loop ring resonators. This paper also discusses the transmission characteristics of asymmetric two open-loop ring resonators varys with ...

A novel bandpass filter with dual-mode open-loop resonators

2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE), 2017
In this paper, we propose a novel microstrip bandpass filter (BPF) based on dual-mode open-loop resonators (DMOLRs). The proposed bandpass filter consists of two coupled DMOLRs, which can be treated as the combination of a folded T-shape stub and a W-shape stub.

Cross-Coupled Bandpass Filter using Microstrip Triangular Open-Loop Resonators

2001 31st European Microwave Conference, 2001
A new cross-coupled planar microwave filter is proposed using coupled microstrip triangular open-loop resonators. The full-wave EM simulator is used to design the triangular resonator and to calculate the coupling coefficients of three basic coupling structures encountered in this type of filter.

Side-Coupled Microstrip Open-Loop Resonator for Harmonic-Suppressed Bandpass Filters

IEICE Transactions on Electronics, 2005
A side-coupled microstrip open-loop resonator is presented for design of harmonic-suppressed bandpass filters with compact size. In geometry, the open-ended microstrip feed line is put in close proximity to the loop resonator at the opposite side of an opened-gap.

ANN Modelling of Planar Filters Using Square Open Loop DGS Resonators

2019
This paper presents a novel modelling method for planar defected ground structure (DGS) square open loop resonator filters. The increased complexity of the coupling mechanism between the resonators and the impossibility to analytically calculate the coupling coefficients created the need of accurate modelling of the coupled resonators.

Analysis and Synthesis of the Square Open Loop Resonators in Microstrip Technology

2013
In the modern microwave communication systems, bandpass filters play an important role. As the demands for filters with high selectivity and low insertion loss grows, new design methods and filters are offered day by day. When working at microwave frequencies, using the typical LC filters results in filters with a poor performance, as the passive ...
