Tunable Bandstop HMSIW Filter With Flexible Center Frequency and Bandwidth Using Liquid Crystal
IEEE Access, 2019 This paper reports on a tunable bandstop filter (BSF) with both flexible center frequency and bandwidth. The tunable BSF is based on half-mode substrate integrated waveguide (HMSIW), of which the broadside is coupled with reconfigurable resonators. Using

High Tc superconducting CPW bandstop filters
IEEE Microwave and Guided Wave Letters, 1996 We have designed and tested a superconducting coplanar waveguide bandstop filter. At a center frequency of 2.84 GHz, a 94% bandwidth low-pass Chebychev design resulted in a filter with less than 0.5 dB in the passband and more than 40-dB insertion loss in the stopband at 35 K.

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 ...
