Design of a switchable microstrip bandstop filter with signal/dual stopbands

IET Microwaves, Antennas & Propagation, 2021
A switchable bandstop filter is proposed herein. In order to achieve switchability between a single ultra‐wide stopband and dual wide stopbands, a complex process of coupling synthesis is not necessarily required.

4-Pole Tunable Absorptive Bandstop Filters Using Folded Coupled-Lines With an Inductor

IEEE Access, 2022
The ever-growing field of wireless communication requires efficient radio frequency transceivers with tunable absorptive bandstop filters that can prevent the interference of out-of-band and reflected signals.

Novel Selective Feeding Scheme Integrated With SPDT Switches for a Reconfigurable Bandpass-to-Bandstop Filter

IEEE Access, 2021
This paper demonstrates a new technique for designing high performance reconfigurable bandpass-to-bandstop filters by employing a ring resonator and a selective feeding scheme integrated with single-pole double-throw switches (SPDT).

Experimental Testing of Bandstop Wave Filter to Mitigate Wave Reflections in Bilateral Teleoperation

Robotics, 2020
A bilateral teleoperation system can become unstable in the presence of a modest time delay. However, the wave variable algorithm provides stable operation for any fixed time delay using passivity arguments.

Abnormal Enhanced Gamma Synchronization in the Default Mode Network Associated With Chronic Pain. [PDF]

Eur J Neurol
This study enrolled 42 chronic pain patients and 42 healthy controls, applying phase‐based connectivity, graph theory, dynamic connectivity analyses, and machine learning to analyze EEG data. It revealed that chronic pain patients showed increased dynamic gamma synchronization within the default mode network (DMN), as well as enhanced resting‐state ...

Compact Wide-Frequency Tunable Filter With Switchable Bandpass and Bandstop Frequency Response

IEEE Access, 2019
In this paper, a novel compact wide-frequency tunable filter with switchable bandpass and bandstop frequency response is presented. By employing two PIN diodes between the source and load port, the bandpass and bandstop filtering response can be switched,

Dual-mode microstrip bandstop filters

2008 Asia-Pacific Microwave Conference, 2008
In this study, we proposed a novel bandstop filter using a square loop resonator. Dual-mode microstrip bandstop filters are designed and realized by employing two degenerate modes of a dual-mode microstrip square loop resonators. Microstrip loop resonators have been used extensively for bandpass filter applications.

Characterizing a Tune All Bandstop Filter [PDF]

2009 International Microwave Workshop Series on Signal Integrity and High-Speed Interconnects, 2009
In this paper a reconfigurable bandstop filter able to reconfigure central frequency, bandwidth and selectivity for fine tuning applications is presented. The reconfigurable filter topology has four poles and a quasielliptic bandstop filter response. The filter is tuned by varactor diodes placed at different locations on the filter topology.
