Abstract
This letter presents a new resonator configuration to design a triple-passband filter with high passband selectivity and compact circuit size. The filter includes two multipath-embedded stepped impedance resonators (SIRs), connected with magnetically coupling by via hole technique at the symmetric plane of the filter. The multipath-embedded SIR is designed at 1.575, 2.45, and 3.5 GHz. The resonant frequencies can be easily controlled by tuning impedance ratio K i and length ratio αi (where i = 1, 2, and 3) of the multipath-embedded SIR. This study provides an effective method to easily design the triple-passband filter with compact circuit size, high passband selectivity and low insertion loss.
