Description
Technical field
The utility model relates to a kind of novel waveguide device.Micro-direction of wave travel can there is the torsion of 90 degree in these components and parts specifically, and the polarised direction that can realize microwave is turned round and turn 90 degrees.
Background technology
In the electronic system of waveguide microwave signal, there is a lot of places to need turning 90 degree simultaneously, and need to reverse polarization of electromagnetic wave direction.In traditional communication system, first method is 90 degree of combination realizations of turning of adding a H face with the turning of 90 degree, an E face; Second method is the turning realization that employing one section of waveguide twist adds 90 degree again.No matter adopt which kind of mode, all need two components and parts, not only volume is large, and cost is high, assembles dumb; Too much components and parts also can cause systematic function and reliability decrease.If adopt the mode of waveguide twist in addition, can not process by the mode of the machining of routine, special processing technology must be had, more add the cost of product.
In prior art (patent No.: ZL 2012 20174272.X), microwave plumbing 90 degree of turning mechanisms are merely able to be turned 90 degree in microwave propagation direction, and there is no the function of rotation of polarization, realize the function of rotation of polarization, two microwave plumbings, 90 degree of turning mechanisms are needed to realize, the increase of cost and volume can be brought like this, also can worsen the electrical performance indexes of system simultaneously.
Another patent application 201410454504.0 is with microwave waveguide pipeline 90 degree of turning mechanisms of twist-reflector function, and two waveguide mouths between this twist-reflector device perpendicular polarization can not be symmetrical with center line, thus has many occasions and inapplicable.
Summary of the invention
The utility model object is to provide a kind of structural volume little for the defect of prior art, easily processes, easy for installation, and the waveguide 90 degree turning structure of the band twist-reflector function of two orthogonal waveguide opening's edge center line symmetries of polarization.
The utility model for achieving the above object, adopts following technical scheme:
A kind of waveguide 90 degree turning structure with twist-reflector function, comprise body, described body has orthogonal horizontal polarization waveguide channels and perpendicular polarization waveguide channels, it is characterized in that: be connected with multi-stage stairs structure by a butterfly cavity between described horizontal polarization waveguide channels and perpendicular polarization waveguide channels.

Embodiment
A kind of waveguide 90 degree turning structure with twist-reflector function as shown in Figure 1, 2, comprise body, described body has orthogonal rectangular horizontal polarized wave conduit 11 and rectangular vertical polarized wave conduit 41, be connected with three grades of vertical step structure 3 by a butterfly cavity 2 between described rectangular horizontal polarized wave conduit 11 and rectangular vertical polarized wave conduit 41.The rectangular horizontal poled waveguide mouth of pipe 1 and the rectangular vertical poled waveguide mouth of pipe 4 are symmetrical along the center line of described body.
For the ease of processing, described turning structure is combined by two metal partss, and rectangular horizontal polarized wave conduit 11 and multi-stage stairs structure 3 are processed in parts, and rectangular vertical polarized wave conduit 41 and butterfly cavity 2 are processed in another parts.Two pieces of metal partss are processed respectively, then assemble.Structure is simple, and waveguide opening's edge center line is symmetrical, and consistency has a good guarantee, and facilitates large-scale production, is also applicable to occasion waveguide locations being had to strict demand.
The lumenal cross-section area equation of described rectangular horizontal polarized wave conduit 4 and rectangular vertical poled waveguide pipeline 1.
The operation principle of the waveguide 90 degree exchanging structure of the utility model band twist-reflector function is: have increase butterfly structure and several steps in the junction of two vertical waveguide of two polarization differences 90 degree, when electromagnetic wave signal arrives this place, pass through butterfly structure, polarization of electromagnetic wave direction is made first to there occurs the torsion of 90 degree, then because the turning of 90 degree also occurs for the effect direction of propagation of step.Thus realize the torsion that polarised direction and the direction of propagation occur 90 degree simultaneously.The utility model turning structure has the good echo performance of wider bandwidth sum.By optimizing the parameter of step and butterfly structure, the electrical property of needs can be obtained.
