Abstract
A stripline filter is disclosed having two stripline resonators which are mutually coupled. In order to be able to influence the type of coupling, such as inductive, capacitive or a combination thereof, the distance between the stripline resonators changes along their length. If the stripline resonators are shorted at the end where the distance between them has a minimum value, then the coupling is substantially inductive. If the stripline resonators are open or capacitively loaded at the end where the distance between the resonators has a minimum value, then the coupling is substantially capacitive.
