Abstract :
This paper presents a novel configuration for dual mode filters operating in the TE/sub 11n/ modes. The use of the proposed configurations in the design of dual mode filters leads to a significant reduction in the filter footprint. Techniques to suppress the TE/sub 21n/ modes in a TE/sub 113/ cylindrical cavity filter are proposed by using a trifurcated iris arrangement. Simulated and experimental results are presented to verify the validity of the proposed configuration.
