Its structure is simpler, easy processing, and the cost is lower.
Description
Technical field
The utility model relates to communication technique field, particularly relates to a kind of directional coupler.
Background technology
Current waveguide-coupled structure more commonly cross directional coupled structure, and cross directional coupler almost all adopts right-angled intersection coupling aperture to realize, right-angled intersection coupling aperture has following deficiency:
The first, cross bore coupling needs adjustment cross recessed angle, and it is more, more responsive that it introduces variable; The second, cross-shaped groove structure is too complicated, and requirement on machining accuracy is very high, high to machining requirements, and difficult realization, causes rate of finished products not high.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of directional coupler, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, it is simpler that the purpose of this utility model is to provide a kind of structure, easily processes, the directional coupler that cost is lower.
Directional coupler of the present utility model, it comprises waveguide channels and coupled structure, described waveguide channels comprises first wave guide passage and Second Wave pathway, described first wave guide passage and Second Wave pathway intersect mutually, described coupled structure is positioned at infall, this coupled structure is the linear through hole in the edge side of having, and this through hole is through described infall.
Further, described coupled structure is tetragonal through hole.
Further, described coupled structure is rectangular through-hole.
Further, described coupled structure is rhombus through hole.
Further, described coupled structure and be provided with gap between first wave guide passage and Second Wave pathway, further, the distance between described coupled structure and Second Wave pathway is 0.1 ~ 1.5mm.
By such scheme, the utility model at least has the following advantages:
The simpler rectangular opening of the utility model structure replaces cross recess, and its variable is less, and susceptibility is lower, and the processing of rectangular opening is easier, suitability for scale production.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model directional coupler.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
In description of the present utility model, it will be appreciated that, term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width ", " thickness ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", " outward ", " clockwise ", orientation or the position relationship of the instruction such as " counterclockwise " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In the utility model, unless otherwise clearly defined and limited, the term such as term " installation ", " being connected ", " connection ", " fixing " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or integral; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals or the interaction relationship of two elements.For the ordinary skill in the art, the concrete meaning of above-mentioned term in the utility model can be understood as the case may be.
In the utility model, unless otherwise clearly defined and limited, fisrt feature second feature it " on " or D score can comprise the first and second features and directly contact, also can comprise the first and second features and not be directly contact but by the other characterisation contact between them.And, fisrt feature second feature " on ", " top " and " above " comprise fisrt feature directly over second feature and oblique upper, or only represent that fisrt feature level height is higher than second feature.Fisrt feature second feature " under ", " below " and " below " comprise fisrt feature immediately below second feature and tiltedly below, or only represent that fisrt feature level height is less than second feature.
See Fig. 1, directional coupler described in the utility model one preferred embodiment, comprise waveguide channels and coupled structure, described waveguide channels comprises first wave guide passage 1 and Second Wave pathway 2, described first wave guide passage 1 and Second Wave pathway 2 intersect mutually, described coupled structure 3 is positioned at infall, and this coupled structure 3 is polygon, and this coupled structure 3 and be provided with gap between first wave guide passage 1 and Second Wave pathway 2.Distance between described coupled structure 3 and Second Wave pathway 2 is 0.1 ~ 1.5mm.Wherein coupled structure 3 is 2, is distributed in two corners of infall, and coupled structure also can be one or more.In the present embodiment, coupled structure 3 preferably adopts rectangular through-hole structure, waveguide channels is metallic conduit, the sidewall being fixed on directional coupler is closed in described first wave guide passage 1 one end, after the bending of described first wave guide passage 1 median straight angle, the other end closes the adjacent wall being fixed on directional coupler, and the relative sidewall being fixed on directional coupler is closed at described Second Wave pathway 2 two ends respectively.Coupled structure 3 its as electromagnetic coupling channel.
It should be noted that, waveguide channels is a kind of hollow, that inwall is very bright and clean metal catheter or interior metallized pipe; Waveguide channels is used for transmitting uhf electromagnetic wave, can be sent to destination by pulse signal with minimum loss; The size of waveguide channels internal diameter is different because of the wavelength of institute's signal transmission; It is used for the radio art such as centimetre radio communication involving millimeter wave, radar, navigation.Waveguide channels can be rectangular waveguide, circular waveguide, semicircular waveguide, radar wave conduit or fiber waveguide pipe.
It should be noted that coupled structure can be quadrangle or pentagon through hole, preferably rectangular through-hole, also can be rhombus through hole, as long as can the side's of meeting coupled structure shape that is linear and overlapping index requirement all drop in protection range of the present utility model.
The above is only preferred implementation of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection range of the present utility model.
