A Tri-band Bandpass Filter Using Short-stub Loaded SIR

摘要：

　　A novel compact triple-passband bandpass filter is presented in this paper.A shorted-stub is loaded to a stepped-impedance resonator(SIR).The resonant frequencies are determined by the length of the loaded-stub and the impedance ratio of the SIR.The input and output port are coupled to the resonator by utilizing pseudo-interdigital structure.A two-pole microstrip triple-passband bandpass filter with central frequencies 1.5 GHz,2.4 GHz and 5.78 GHz is designed for GPS and WLAN applications.
