Varactor-tuned dual-band filter with constant absolute bandwidth

This paper proposed a novel varactor-tuned dual-band filter with constant absolute bandwidth. It is composed of a pair of half-wavelength open-ended resonators and a pair of quarter-wavelength short-ended resonators. The resonators utilized two different methods to control the electric and magnetic...
