Abstract
The present invention discloses a waveguide square and round converting member which is characterized in that the member is an integrated structure with multiple stepped cavities, two ends of the member are round and rectangular waveguide interfaces, the rectangular waveguide interface is corresponding to a rectangular cavity with a chamfer, the round waveguide interface is corresponding to a round cavity, a gradual change cavities with convergent sizes are orderly arranged between the convergent and the rectangular cavity, and the cavities are gradually changed from round to rectangle. According to the waveguide square and round converting member, the integrated structure is used, and the reliability is high. Through multiple gradual change cavities with arcs, the transition between the round waveguide and the standard rectangular waveguide is realized, and thus the conversion structure has a wide operating bandwidth. The size of each gradual change cavity is smaller than that of an adjacent outer-order gradual change cavity so as to realize the processing of one part. The processing guide angle of each gradual change cavity is equal to 1/2 of an inner cavity narrow side, large diameter milling processing is used as possible, and the waveguide square and round converting member has the advantages of simple structure and easy processing.
Description
Technical field
The invention belongs to telecommunications field, particularly relate to a kind of waveguide circumference converting member.
Background technology
Circular waveguide and rectangular waveguide are two kinds of the most frequently used waveguide transmission lines, and the pattern of rectangular waveguide transmission is TE10 pattern.Because system usually needs polarization multiplexing function, for realizing this function, in circular waveguide, need to use the TE11 pattern with polarization degeneracy.The installation of system conveniently antenna in addition, also usually practical circular waveguide, therefore need the circumference switch transition of circular waveguide to rectangular waveguide.
Waveguide circumference transition before has gradual change form and has the transient mode of stepped form.Gradual transition mode has the good standing wave performance of very wide bandwidth sum, but is level and smooth gradual transition owing to being this transformational structure, and therefore transition structure is very long, and needing special ball cutter in addition could process, and therefore processing charges is very expensive, and volume is larger.In order to overcome the shortcoming of this gradual transition, the transient mode of stepped form that what people invented again have, but the transition of before all stepped form has the shortcoming of work strip width, in addition because the problem of this body structure, all transition bands all need to be divided into several part to process, and are then assembled by inner mode of inlaying.Will cost be increased like this, reduce reliability, and the waterproof difficulty of whole system can be increased.
Summary of the invention
The object of the invention is to provide a kind of structure simple for the defect of existing waveguide circumference converting member, and work strip is wide, the integral type waveguide circumference converting member of reliability height and easily processing.
The present invention for achieving the above object, adopts following technical scheme:
A kind of waveguide circumference converting member, it is characterized in that: these parts are the integrative-structure with multiple step cavity, two ends are respectively circular and long rectangular wave waveguide interface; Described long rectangular wave waveguide interface is corresponding to the rectangle cavity with chamfering, and described circular waveguide interface corresponds to circular cavity; Be disposed with the gradual change cavity of size convergent between described circular cavity and rectangle cavity, described cavity by circle to rectangle gradual change.
It is further characterized in that: the gradual change cavity size connected with described circular cavity is maximum, and the gradual change cavity size connected with described rectangle cavity is minimum.
Further: described gradual change cavity cross-section is that middle part has flat segments, and two ends are the shape of semi arch.
The gradual change cavity connected with described circular cavity is to the gradual change cavity connected with described rectangle cavity, and its middle flat segments length increases gradually, and its two ends semi arch radius reduces gradually.
Preferred: described gradual change cavity is four.
The present invention adopts integral structure, and reliability is high.Realize transition between circular waveguide and standard rectangular waveguide by multiple tapering chambers with circular arc, make this transformational structure have very wide bandwidth of operation.Each gradual change cavity size is less than the size of the outer single order gradual change cavity adjacent with it, to realize a part processing.The processing lead angle of each gradual change cavity equals 1/2 of the narrow limit of this inner chamber, to adopt large diameter milling cutter to process as much as possible, has the advantage that structure is simple, be convenient to processing.

Embodiment
A waveguide circumference converting member as shown in Figure 1, 2, these parts are the integrative-structure with multiple step cavity, and two ends are respectively circular and long rectangular wave waveguide interface; Described long rectangular wave waveguide interface is corresponding to the rectangle cavity 1 with chamfering, and described circular waveguide interface corresponds to circular cavity 6; Be disposed with the gradual change cavity 2,3,4,5 of four size convergents between described circular cavity 6 and rectangle cavity 1, gradual change cavity 5 size connected with described circular cavity 6 is maximum, and gradual change cavity 2 size connected with described rectangle cavity 1 is minimum.
Described gradual change cavity 2,3,4,5 cross section is that middle part has flat segments, and two ends are the shape of semi arch.The gradual change cavity 5 connected with described circular cavity 6 is to the gradual change cavity 2 connected with described rectangle cavity 1, and its middle flat segments length increases gradually, and its two ends semi arch radius reduces gradually.
According to same principle, according to the actual needs, this transformational structure can be designed to other exponent number.Generally speaking, exponent number is more, and bandwidth of operation is wider, and echo is also better; But corresponding shortcoming is that the volume of product is also larger, and processing cost is also higher, therefore need the exponent number determining transformational structure according to actual conditions.
The present invention except the inner chamber lead angle of first order rectangle cavity very little, outside match-on criterion rectangular waveguide, the radius of the gradual change cavity inner chamber lead angle of other grades is all 1/2 of its narrow limit; Be convenient to like this process with maximum milling cutter; The long limit of gradual change cavity inner chamber and narrow limit size are all that inner size is less than outside size, guarantee integration processing.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
