Abstract :
In this paper a study of some planar microwave bandpass filters composed of defected ground resonators is presented. Different kinds of couplings between two defected ground resonators are investigated: electric coupling, magnetic coupling and two different mixed couplings. The values of the coupling coefficients are extracted from the simulation results, obtained by using full-wave EM-field simulation software. On the basis of this study, some second-order coupled planar microwave bandpass Chebyshev filters are designed. The simulated performances of these novel filter structures are very close to the filter requirements, validating this way the design method and its results
