Microstrip Filters with Adjustable Transmission Zeros Using Inductive-coupled Open Stub-loaded Resonators
This paper presents two compact microstrip bandpass filters using inductive-coupled open stub-loaded resonator.The character of the open stub-loaded resonator is studied.One adjustable transmission zero above the pass band of the filters is got by the open stub,which greatly improves the stopband rejection of the filter.The short-circuited stub is introduced to generate inductive-coupling between the resonators.In order to create more transmission zeros,cross-coupling between the source and load is introduced in the second filter design.The simulated and measured results agree very well which has demonstrated the validation of our design.
