Description
Technical field
The utility model relates to waveguide transitions technical field, particularly relates to a kind of coaxial rectangular waveguide transducer.
Background technology
In order to realize reducing insertion loss in the transfer process between waveguide and coaxial line, the means that prior art is taked are in waveguide, arrange stair-stepping impedance transformation block, coaxial fitting are directly inserted the impedance transformation block in waveguide.Therefore, an impedance transformation block must be set in waveguide, and the position of impedance transformation block is once can not change after determining.But in actual treatment, the connection between impedance transformation block and waveguide is also insecure, usually can produce mobile in carrying or installation process.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of coaxial rectangular waveguide transducer, and the structure of waveguide self can be utilized to realize impedance matching.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of coaxial rectangular waveguide transducer, described coaxial rectangular waveguide transducer comprises waveguide, coaxial fitting, impedance transformation block and medium sleeve, wherein, described waveguide end opening, the other end is closed, and described waveguide has and caves in towards the multi-stage stairs shape of described waveguide inside, and the height of described multi-stage stairs shape depression reduces from closed one end of described waveguide successively to the other end; Described impedance transformation block is positioned at described waveguide inside and is connected in top step-like depression; Described coaxial fitting is connected to closed one end of described waveguide and the axis of described coaxial fitting is consistent with the electromagnetic transmission direction of described waveguide, and it is inner that described coaxial fitting stretches into described waveguide, and insert in described impedance transformation block; Closed one end of described waveguide is located at by described medium sleeve, and is enclosed within described coaxial fitting.
Preferably, described step-like depression is at least three grades.
Preferably, described multi-stage stairs shape depression is equal with the distance of the both sides sidewall of described waveguide.
The beneficial effects of the utility model are: the situation being different from prior art, coaxial rectangular waveguide transducer of the present utility model arranges multi-stage stairs shape depression and replaces traditional stepped impedance transformation block in waveguide, thus the structure of waveguide self can be utilized to realize impedance matching, owing to not needing to adopt stepped impedance transformation block, the composition of waveguide can be reduced, reduce the manufacturing cost of waveguide.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of the coaxial rectangular waveguide converter embodiment of the utility model.
Fig. 2 is the schematic top plan view of the coaxial rectangular waveguide converter embodiment of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Please also refer to Fig. 1 and Fig. 2.The coaxial rectangular waveguide transducer of the utility model embodiment comprises waveguide 1, coaxial fitting 2, impedance transformation block 3 and medium sleeve 4.Wherein, waveguide 1 one end open, the other end is closed, and waveguide 1 has towards the multi-stage stairs shape depression 11 of waveguide 1 inside, the height of multi-stage stairs shape depression 11 reduces from closed one end of waveguide 1 successively to the other end; Impedance transformation block 3 is positioned at waveguide inside and is connected in top step-like depression 11; Coaxial fitting 2 is connected to closed one end of waveguide 1 and the axis of coaxial fitting 2 is consistent with the electromagnetic transmission direction of waveguide 1, and it is inner that coaxial fitting 2 stretches into waveguide 1, and insert in impedance transformation block 3.In the present embodiment, step-like depression 11 is at least three grades, and multi-stage stairs shape depression 11 is equal with the distance of the both sides sidewall of waveguide 1.Waveguide 1 can be circular waveguide or rectangular waveguide.Closed one end of waveguide 1 is located at by medium sleeve 4, and is enclosed within coaxial fitting 2.
Wherein, the processing mode of multi-stage stairs shape depression 11 is fairly simple, and processing cost is low, can be obtained by one time punching molded.Multi-stage stairs shape depression 11 is equivalent to traditional stepped impedance transformation block, and traditional stepped impedance transformation block can be replaced to realize impedance matching.And the insertion size of different coaxial fittings 2 can be adapted to by the position of adjustment impedance transformation block 3.By adding medium sleeve 4, the equiva lent impedance of waveguide 1 can be reduced, reducing the sensitiveness of impedance versus frequency change, thus the frequency band of broadening coaxial fitting 2.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
