摘要

In this paper a multilayer dual-mode complementary filter is developed based on the substrate integrated circular and elliptic cavity (SICC and SIEC). The filter is constructed with a SICC and double SIECs, and each cavity supports two degenerate modes, which can be generated and controlled by the coupling aperture and the slot located between layers. With multilayer topology, the structures can exhibit vertical coupling between vertically stacked dual-mode cavities. It does not only have the good performance, but also reduces the circuit size much more. Moreover, sharp transition characteristic in both the lower side and the upper side demonstrates high selectivity of the filter. Good agreement is obtained between the simulated and measured results of the proposed structure.
