Abstract

The invention provides a dielectric waveguide filter, comprising at least two resonators, the resonators are coupled through a coupling structure, the coupling structure includes a conductor pattern and a blind hole connected to the conductor image, the conductor pattern is located between the resonators, the blind The hole is located inside the resonator, so that the coupling strength of the coupling structure can be adjusted by adjusting the size of the conductor pattern and / or the blind hole, and then it is not necessary to adjust the coupling strength of the coupling structure only by adjusting the size of the conductor pattern, thereby improving the pattern coupling. If the amount is too large, it will cause harmonics at the near end. Moreover, by flexibly adjusting the size of the conductor pattern and / or the blind hole, the position of the harmonic can be greatly adjusted, so that the range of harmonic adjustment is large.

Description

technical field [0001] The present invention relates to the technical field of filters, more specifically, to a dielectric waveguide filter. Background technique [0002] With the development of communication systems, the requirements for filters continue to increase. Limited by the cavity size and weight requirements, the miniaturization and weight reduction of filters has gradually become a trend. Using the high dielectric constant and high Q value of the material, the dielectric waveguide filter can greatly reduce the size and weight of the product, and also has the advantages of small temperature drift. [0003] In existing dielectric waveguide filters, two or more layers of resonator structures need to use pattern coupling for energy transfer. like figure 1 As shown, 101 and 102 are the resonators of the dielectric waveguide filter respectively, and the resonator 101 and the resonator 102 are connected through the pattern 103 and the pattern 104. By adjusting the dia...
