First, two open-loop resonators operating at different resonances are employed. Then, one of the open-loop resonators is substituted by a ( 4) short-circuited transmission line, thus resulting into a more compact structure. Properties of these configurations are discussed, and two manufactured prototypes have been sucessfully tested. The results showthe usefullness and validity of the new structures with high rejection capabilities.
