Abstract :
The design of compact and very selective dual band dual-mode filter with improved isolation is introduced in this paper. The two passbands are achieved by connecting two stepped-impedance dual-mode resonators in parallel. Two transmission zeros are obtained on both sides of each passband with the use of the source-load coupling. Theoretical analysis together with experimental prototype is presented.
