✦ Synopsis

In this article, a new method is suggested to improve the frequency responses of dual-mode waveguide filters employing cross-shaped slots. According to this method, regarding one cross-shaped slot between two cavities, the horizontal (vertical) mode in one cavity influences the vertical (horizontal) mode in the other cavity to a much lesser extent. It enhances the overall performances. A 4 th -order dual-mode filter is used as an example and it validates the method.
