Embodiment Construction
[0041] In order to make the object, technical solution and advantages of the invention clearer, typical specific implementation modes of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation cases described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0042] The present invention aims to provide a dielectric waveguide filter, which increases the remote harmonic suppression of the dielectric waveguide filter by providing a coupling structure for high-order modes, and improves the suppression frequency range.
[0043] It should be noted that each first resonant cavity 10 has its own first higher-order mode and a second higher-order mode, and the first higher-order mode and second higher-order mode of each first resonant cavity 10 Secondary modes refer to two higher-order modes that are closest in f...
