Abstract
In this paper, new design concept of nonorthogonal input and output (I/O) ports applied to optimize dual‐mode bandpass ring filter is proposed. Compared to conventional dual‐mode filters, the proposed filter with nonorthogonal I/O could not only support two degenerate modes operation, but also increase design flexibility. Moreover, the design of dual‐mode filters would not have an I/O geometry limitation, corresponding to high integration. Finally, a simple structure and high selectivity for the dual‐mode bandpass filters were obtained. © 2006 Wiley Periodicals, Inc.
