Microstrip tunable bandstop filter with constant absolute bandwidth [PDF]
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.

FREQUENCY-TUNABLE BANDPASS FILTERS WITH CONSTANT ABSOLUTE BANDWIDTH AND IMPROVED LINEARITY [PDF]
Progress In Electromagnetics Research Letters, 2012 This paper presents a frequency-tunable bandpass fllter with constant absolute bandwidth and improved linearity. The proposed resonator is composed of an open-ended transmission line with back-to-back varactor diodes loaded at one end. The back-to-back varactor diodes are used to enhance the linearity of the fllter, which is better than that of the ...

A planar vertically-integrated tunable filter/antenna with constant absolute bandwidth
2017 IEEE MTT-S International Microwave Symposium (IMS), 2017 This paper presents a vertically-integrated second-order tunable planar filter/antenna that expands upon previous work with tunable filter/antennas. This work demonstrates the use of a radiating element as a resonator in the filter and uses mixed electric and magnetic coupling to achieve a constant absolute bandwidth over the filter tuning range ...
