Abstract: A novel multilayer coupled stripline resonator structure is introduced to realize miniature broadband bandpass filters.Two possible filter configurations are proposed in this paper: two-layer coupled stripline resonators with shielded layers connected by side metal printing and three-layer coupled stripline resonators with shielded layers connected by side metal vias.Wider band and good selectivity are obtained by exploiting four resonators.By using the defected ground structure(DGS),the filter exhibits a high rejection in stopband.The technology of low temperature co-fired ceramic(LTCC) is employed to manufacture the filters.Experiment results of one kind of the filters are presented and the measurement data are in agreements with the results of the simulation.
