Abstract
- ABSTRACT A novel structure for dual-band substrate integrated waveguide filters is presented in this article. To obtain advantages of compact structure and good performance, complementary split-ring resonators (CSRRs) are simplified, and loaded into the waveguide surface with complementary spiral resonators (CSRs) together. As a result, two passbands below the cutoff frequency of the waveguide are obtained. Every passband has two transmission zeros and two transmission poles. This article points out that the combination of CSRRs and CSRs cannot only make the structure more compact, but also produce a positive interaction between the resonators, providing a new direction for the application of those two right/left-hand structures. To verify the presented concept, the filter is fabricated. The measured results are in good agreement with the simulation. © 2016 Wiley Periodicals, Inc.
