[0064] In order to achieve the above Figure 8 coupling mechanism, the present invention proposes a connection structure between non-adjacent resonant cavities that are vertically staggered coupled. Figure 10A A structure of resonant cavity coupling of non-adjacent layers according to an embodiment of the present invention is shown. Figure 10B draw Figure 10A side view, Figure 10C draw Figure 10A front view. exist Figure 10A , 10B In , 10C, resonant cavities between non-adjacent layers are omitted to make the diagram easier to read. In the following figures, the upper and lower resonant cavities are respectively Figure 8 The resonant cavity 1 and the resonant cavity 4 are used as an illustration, but are not intended to limit the actual structure of the present invention.

[0065] Such as Figures 10A-10C As shown, the resonant cavity 100 (equivalent to the above-mentioned resonant cavity 1 ) has a first metal layer (surface) 102 , a dielectric layer 108 and a ...

[0075] Figure 15A A schematic structural diagram of a second embodiment of the present invention is shown. In this embodiment, it is achieved by using the coupling of the resonant cavity turning extension structure. Such as Figure 15A As shown, the two sides of the resonant cavity 200 are made into turning extension structures 200a, 200b. In addition, a slot 200c is further formed in the extension structure 200a, and a slot (not shown) is also formed in the extension structure 200b in the same manner. Similarly, the two sides of the resonant cavity 202 are also made into turning extension structures 202a, 202b, and slot holes 202c, 202d are respectively formed in the turning extension structures 202a, 202b. Afterwards, the turning and extending structures 200a, 200b of the upper resonant cavity 200 are brought into corresponding contact with the turning and extending structures 202a, 202b of the lower resonating cavity 202, so as to achieve Figure 15A The bilaterally co...

Abstract

The invention discloses a non-adjacent vertical resonant-cavity coupled structure and a manufacturing method thereof. The non-adjacent vertical resonant-cavity coupled structure at least comprises a first resonant-cavity and a second resonant-cavity, a dielectric material layer, at least one first high-frequency transmission line and one second high-frequency transmission line and at least one communication pole. The first resonant-cavity and the second resonant-cavity respectively have a first metal surface and a second metal surface corresponding to each other; wherein, the respective second metal surfaces of the first resonant-cavity and the second resonant-cavity are collocated corresponding to each other. The dielectric material layer is arranged between the second metal surfaces of the first resonant-cavity and the second resonant-cavity. The first high-frequency transmission line is arranged on a side edge of the first surface corresponding to the first resonant-cavity, and thesecond high-frequency transmission line is arranged on the edge of a side edge corresponding to the second resonant-cavity; and the communication pole is vertically connected with the first high-frequency transmission line and the second high-frequency transmission line.

Description

technical field [0001] The invention relates to a coupling structure of resonant cavities, and in particular to a coupling structure of non-adjacent resonant cavities. Background technique [0002] In wireless communication systems, frequency selective components such as filters, duplexers, multiplexers, etc. are indispensable key components of the RF front end. Its function is to select or filter / attenuate signals or noise in a specific frequency range in the frequency domain, so that the subsequent circuit can receive signals in the correct frequency range for processing. [0003] In microwave (1GHz-40GHz) and millimeter wave (40GHz-300GHz) frequency ranges, large-scale systems often use waveguide tubes to construct the entire RF front-end circuit. The waveguide has the advantages of being able to withstand high power and extremely low loss, but the minimum size of the waveguide is limited due to the characteristic of the cutoff frequency. In addition, since the waveguid...
