Continuously Tunable Dual-Mode Bandstop Filter [PDF]
IEEE Microwave and Wireless Components Letters, 2018 A varactor-based tunable bandstop filter has been proposed in this article. The proposed filter is based on a dualmode circuit developed by introducing inductive and capacitive couplings into a notch filter. The frequency tunability is achieved by using varactor diodes instead of the lumped capacitors in the circuit.

Design of tunable microstrip bandstop filter
2016 Asia-Pacific Microwave Conference (APMC), 2016 In this paper, a novel microstrip bandstop filter with tunable center frequency and bandwidth is introduced. A dual-mode square loop resonator and three varactor diodes are used to achieve the tunability operation. The dual-mode square loop resonator is coupled to a straight transmission line that connects input and output ports.
