A Novel Reconfigurable Bandpass Filter Using Varactor-Tuned Stepped-Impedance-Stubs

摘要：

　　A novel reconfigurable bandpass filter using varactor-tuned stepped impedance resonator (SIR) is introduced to achieve tunable central frequency and bandwidth.The varactor-tuned stepped impedance resonator structure consists of a stepped impedance with open or shortcircuited stub and a varactor between the stubs.Its convenient to change the transmission zeros with the appropriate DC voltage controlling the values of varactor capacitors.In addition, the ratios between the two sections of SIRs can be easily changed to reformulate the resonant frequencies and then more design freedom of filter is obtained.The experimental results validate the design.
