Design and Fabrication of Tri-Stopband Bandstop Filters Using Cascaded and Multi-Armed Methods

Advanced Electromagnetics, 2017
In this paper, we proposed a compact C-open-loop ring resonator and its equivalent circuit. The second cascaded BSF are designed using this simple C-ring resonator.

Miniature Multi-Band Absorptive Bandstop Filter Designs Using Bridged-T Coils

IEEE Access, 2018
In this paper, miniature absorptive bandstop filters (ABSFs) with one to three stopbands are demonstrated. First, the proposed single-band ABSF is realized by the introduction of one lossy resonator to a conventional stub bandstop filter, while the ...

A Tunable Dual-Band Bandpass-to-Bandstop Filter Using p-i-n Diodes and Varactors

IEEE Access, 2018
In this paper, a tunable dual-band bandpass-to-bandstop filter and its analysis are proposed. The bandpass-to-bandstop transformation could be obtained by changing the state of the p-i-n diode.
