Abstract
In this paper, a new design of dual-band filter is proposed based on 3D printable dual-mode cylinder cavity. By externally loading metal cylinder perturbations to the traditional cylinder cavity, a pair of degenerate TE111modes are separated and exploited for realizing dual-band filtering response. Meanwhile, by elaborately rotating the feeding ports to introduce the bypass coupling and constructing the transversal coupling, multiple transmission zeros can be generated, bringing out high frequency selectivity. In order to verify the design concept, a dual-mode dual-band filter operating at 9.95GHz and 10.25GHz is designed, modeled in a 3D printable configuration and validated on the high frequency structure simulation (HFSS).
