Abstract
The utility model discloses a cross rectangular waveguide coupler of polygonal opening coupled structure belongs to microwave communication and radar communication technology field. The utility model discloses a main rectangular waveguide and a vice rectangular waveguide, main rectangular waveguide and vice rectangular waveguide vertical superposition of each other to the common wall of a square is formed in vertical superposition part of each other, the bilateral symmetry sets up two polygon coupling holes that the shape is the same that run through the common wall on the diagonal of common wall. The utility model discloses structural simple compactness, the handling ease, when having realized broadband, high directionality, high isolation still great increase the coupling volume.
Description
Technical field
The utility model belongs to microwave communication and radar leads to technical field, relates generally to a kind of polygonal hole coupled structure
Cross rectangular waveguide coupler.
Background technology
Rectangular waveguide directional coupler is the microwave device being widely used in microwave system and radar system.Guide directional
Coupler mainly has waveguide broadside coupling and Narrow Wall of Waveguide side to couple two kinds of forms, is required according to different structural requirements and coupling amount
Select different coupled modes.Cross rectangular waveguide coupler is one type, mainly by orthogonal major and minor square wave
Lead composition, the coupling aperture using the different structure form on rectangular waveguide broadside overlapping part is realized.
Common coupling pore structure has single hole arrangements and double-pore structure, single hole arrangements because its narrow bandwidth, directionality are poor, every
Seldom it is employed from spending the defects such as poor, coupling amount is little.Using in more double-pore structure, diesis crack structure is extensively made
With.This structure which solves the narrow bandwidth of single hole arrangements, and directionality is poor, every the defects such as isolation difference, coupling amount having than single hole
Lifted, but want to obtain bigger coupling amount diesis crack structure and be similarly difficult to realize because physical dimension limits.
Content of the invention
The utility model purpose is：In order to improve the coupling amount of cross rectangular waveguide coupler further, provide one kind
Structure is simple, with wide, high directivity, high-isolation and the big coupled structure of coupling amount.
Specifically, the utility model employs the following technical solutions realization：The ten of a kind of polygonal hole coupled structure
Font rectangular waveguide coupler, including the secondary rectangular waveguide of a main rectangular waveguide and it is characterised in that：Described main square wave
Lead and the secondary orthogonal overlap of rectangular waveguide, and form a foursquare common wall, described public affairs in orthogonal lap
On the diagonal of wall, both sides are symmetrical arranged two shape identical polygon coupling apertures running through common wall altogether.
In technique scheme, described polygon coupling aperture, its be shaped as by one foursquare one jiao fall 45 ° of corner cut structures
Become, a quarter of this corner cut right-angle side length of side slightly this square length of side, this square length of side is slightly less than the common wall length of side
1/2nd.
In technique scheme, described two polygon coupling apertures are full symmetric.
The beneficial effects of the utility model are as follows：Compared with prior art, on the one hand, simply tight in the utility model structure
Gather, be easy to process.On the other hand, due on common wall both sides be symmetrical arranged can two shape identicals running through common wall many
Side shape coupling aperture is so that cross rectangular waveguide coupler has high bandwidth, high directivity, high-isolation, also greatly simultaneously
Increased coupling amount, electric property has a clear superiority.
Brief description

Fig. 2：Coupled structure plan of the present utility model.
In figure symbology：The main rectangular waveguide of 1-, 2- pair rectangular waveguide, 3- polygon coupling aperture, 4- corner cut, 5- are diagonal
Line.
Specific embodiment
Simultaneously referring to the drawings the utility model is described in further detail with reference to embodiment.
Embodiment 1：
An embodiment of the present utility model, is mainly made up of a main rectangular waveguide 1 and a secondary rectangular waveguide 2, such as
Shown in Fig. 1 and Fig. 2.
As shown in figure 1, main rectangular waveguide 1 and the secondary orthogonal overlap of rectangular waveguide 2, and in orthogonal lap shape
Become a common wall.This common wall is square, and on its diagonal, to be symmetrical arranged two shapes running through common wall identical for both sides
Polygon coupling aperture 3.
As shown in Fig. 2 the shape of polygon coupling aperture 3 can be considered by one foursquare one jiao fall 45 ° of corner cuts 4 constitute, its
The a quarter of the length of side of the right-angle side of corner cut 4 slightly this square length of side, this square length of side is slightly less than the common wall length of side
1/2nd.Polygon coupling aperture 3 is positioned at common wall diagonal 5 both sides and full symmetric.Due to setting of polygon coupling aperture 3
Put so that cross rectangular waveguide coupler has high bandwidth, high directivity, high-isolation, also greatly increased coupling simultaneously
Resultant, has a clear superiority in electric property.
Although the utility model is open as above with preferred embodiment, embodiment is not for limiting the utility model
's.In the spirit and scope without departing from the utility model, any equivalence changes done or retouching, also belong to this practicality new
The protection domain of type.The content that protection domain therefore of the present utility model should be defined with claims hereof is for mark
Accurate.
