N2 - New designs of the dual-band filter realized by distributed circuits are studied in this paper. Series and parallel open stubs are used as the resonators to fulfill the dual-band characteristics. Two dual-band inverters are proposed, which can be easily merged with adjacent resonators to reduce the circuit size. All the theoretical analysis and design procedures are discussed in detail and have been successfully verified by experiment results.
