Abstract
Novel planar dual-band bandpass filters with stepped-impedance resonators have been proposed. The central frequency of dual passbands can be easily controlled by the stepped-impedance resonators. Moreover, two stepped-impedance open stubs can generate transmission zero between two passbands, therefore the isolation can be increased. With the proposed structure, additional transmission zeros will appear around two passbands. In addition, the match between measurement and the theoretical simulation validates the proposed structure.
