Abstract
The invention relates to a microwave orthogonal-mode converter, which can be used for separating or combining two orthogonally polarized microwave signals. The microwave orthogonal-mode converter comprises a straight tube, wherein one end of the straight tube is an inlet, and the other end of the straight tube is a first outlet. The middle of the straight tube is provided with an opening which is connected with a second outlet. The microwave orthogonal-mode converter is characterized in that at least two pairs of opposite holes are formed in a pipe wall, between a longitudinal central line of the second outlet and the first outlet, on the straight pipe, and opposite holes in each pair are respectively and internally provided with a metal needle. The axis of each metal needle is vertically orthogonal to the axis of the straight tube and is vertical to the longitudinal central line of the second outlet. The microwave orthogonal-mode converter in such a way is good in performance and lower in manufacturing cost.
Description
Technical field
The present invention relates to a kind of microwave device.Specifically, be to can be used to make the microwave signal of two orthogonal polarizations to separate or synthetic microwave orthomode transducer.
Background technology
At present on microwave communication equipment; Separate and spread out of in order to make the microwave signal that gets in the microwave pipeline from two different pipelines with two orthogonal polarizations; Two mutually orthogonal polarization microwave signals that get into from different pipelines are synthesized in a microwave pipeline, all need use the microwave orthomode transducer.Traditional microwave orthomode transducer adopts diaphragm to make the microwave signal of two orthogonal polarizations separate or synthesize usually, and this just need slot in microwave pipeline both sides, and diaphragm is placed in the groove.There is following problem in this structure:
1. because the thickness of diaphragm is all very thin, so its size and position be difficult to accurate machining control, makes the performance of microwave orthomode transducer be affected.
2. because the thickness of diaphragm is all very thin, the width of the groove that matches with it is just very little, can only use very little cutter to process, thereby make long processing time, and manufacturing cost is high.
Summary of the invention
The problem that the present invention will solve provides a kind of microwave orthomode transducer, and the performance of this microwave orthomode transducer is good, and manufacturing cost is lower.
For addressing the above problem, adopt following scheme:
Microwave orthomode transducer of the present invention comprises straight tube, and an end of straight tube is import, and the other end is first outlet.There is opening at the middle part of said straight tube, is connected with second outlet on the opening.Be characterized on the tube wall between the second outlet longitudinal centre line and first outlet, at least two pairs of relative perforates being arranged on the said straight tube, each is to being provided with a metal needle in the relative perforate.The axis of said metal needle and the axis of straight tube all intersect vertically, and the axis of metal needle all with second the outlet longitudinal centre line vertical.
Wherein, the cross-section of pipeline of said straight tube is a square or circular.The cross section of said second outlet is a rectangle, and the parallel axes of rectangular longitudinal centre line of this cross section and straight tube.
Take such scheme, have the following advantages:
1. adopt at least two metal needles to replace diaphragms because the pipeline of microwave orthomode transducer of the present invention is interior, and the easy accurate machining control of the size of metal needle and position, thereby make the performance of microwave orthomode transducer improve greatly.
2. owing to adopt at least two metal needles to replace diaphragms in the pipeline of microwave orthomode transducer of the present invention, the perforate on the microwave pipeline that matches with metal needle only need be used less drill bit to process and get final product, thereby makes weak point process time, and manufacturing cost is lower.

Embodiment
To shown in Figure 4, microwave orthomode transducer of the present invention comprises straight tube like Fig. 2, and an end of straight tube is import 1, and the other end is first outlet 4.There is opening at the middle part of said straight tube, is connected with second outlet 2 on the opening.The cross section of second outlet 2 is a rectangle in the present embodiment, and the parallel axes of rectangular longitudinal centre line of this cross section and straight tube.On the tube wall between second outlet 2 longitudinal centre lines and first outlet 4, at least two pairs of relative perforates 3 are arranged on the said straight tube, each is to being provided with a metal needle 5 in the relative perforate 3.The axis of said metal needle 5 and the axis of straight tube all intersect vertically, and the axis of metal needle 5 is all vertical with second outlet, 2 longitudinal centre line.
For the orthogonal polarization microwave signal can be got into smoothly, the straight tube cross section of microwave orthomode transducer of the present invention should be a square or circular.
During work, the microwave signal of two orthogonal polarizations gets into from the import of microwave orthomode transducer of the present invention, and when microwave signal arrived the position of metal needle, the microwave signal vertical with metal needle can be passed through smoothly, and spreads out of from first outlet; And the microwave signal parallel with metal needle turns to owing to the obstruct that receives metal needle, and spreads out of from second outlet, thereby realizes the separation of the microwave signal of two orthogonal polarizations.Oppositely; Can the polarization microwave signal vertical with metal needle be introduced first outlet; And polarization microwave signal that will be parallel with metal needle is introduced second outlet; These two kinds polarization microwave signals get into simultaneously and form the orthogonal polarizations microwave signal behind the straight tube, and spread out of from import department, thereby realize microwave signal synthetic of two orthogonal polarizations.
