Abstract :
In this paper, a new design of dual-band filter realized by distribution circuits is presented. Open stubs in parallel are used as the resonators to fulfil the dual-band characteristics. A structure of dual-band inverters is also proposed, which can be easily merged with adjacent resonators. The design procedures are discussed in detail and verified by experiment results.
