Novel configurations for dual-mode dielectric resonators operating in the HEH/sub 11/ mode or the HEE/sub 11/ mode are presented. The use of the proposed configurations in the design of dual-mode dielectric resonator filters leads to a design with a remarkably improved spurious performance. Techniques to control the frequency separation between the resonance frequencies of the two dual-modes HEH/sub 11/ and HEE/sub 11/ are discussed. Experimental results are presented to verify the validity of the proposed configurations. The proposed configurations promise to be useful in the design of dual-mode dielectric resonator filters for satellite multiplexers having stringent rejection requirements.
