A Parallel Connected Hybrid Microstrip-Substrate Integrated Waveguide Bandstop Filter
Elektronika ir Elektrotechnika, 2023 This study presents an original parallel connected hybrid microstrip-substrate integrated waveguide (PCHM-SIW) bandstop filter. A low-pass filter implemented on a microstrip structure and a SIW-based high-pass filter are connected in parallel to each ...

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.

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.

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.

A COMPACT MICROSTRIP BANDSTOP FILTER [PDF]
Progress In Electromagnetics Research Letters, 2009 In this paper, a novel microstrip bandstop fllter by etching a square split ring in the center of microstrip line is proposed. Low insertion loss in the passband, high rejection level and integrated structure should be mentioned as advantages for this resonator.
