A Novel SFSIW Miniaturized Filter with Tunable Bandwidth and Frenquency

摘要

In this paper, a substrate integrated waveguide microwave filter combining miniaturization and tunable technology is proposed. On the basis of miniaturization, the absolute bandwidth can be adjusted under constant central frequency and the center frequency can be adjusted under constant absolute bandwidth. It lays a solid foundation for the realization of high quality fully tunable filters.
