Design of Tunable Coaxial Bandpass Filter Based on Embedded Stepped Impedance Resonators
IEEE Access, 2023 This paper describes a method for designing tunable coaxial bandpass filters based on an inserted coaxial stepped impedance resonator (SIR). The miniaturization of the coaxial resonator is realized by the shape of the stepped impedance structure.

Microstrip tunable bandstop filter with constant absolute bandwidth
Journal of Electromagnetic Waves and Applications, 2014 This paper presents a novel designing approach for tunable bandstop filters (BSPs) with constant absolute bandwidth (CABW). A simple bandstop unit is introduced to design tunable BSPs. Through the analysis, the bandwidth and center frequency of the unit can be fully controlled.
