The beneficial effects of the utility model are: the situation being different from prior art, rectangular waveguide conversion equipment 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 utility model rectangular waveguide conversion equipment embodiment.
Fig. 2 is that schematic diagram is looked on a left side for the utility model rectangular waveguide conversion equipment embodiment.
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 rectangular waveguide conversion equipment of the utility model embodiment comprises waveguide 1, coaxial fitting 2 and dielectric-slab 3.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, and the inner surface of multi-stage stairs shape depression 11 is covered with impedance transformation layer 12; 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 layer 12.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.Dielectric-slab 3 is strip, and coaxial fitting 2 inserts impedance transformation layer 12 through the middle part of dielectric-slab 3, and the two ends of dielectric-slab 3 abut the inwall of waveguide 1 respectively.
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.Be equivalent to traditional stepped impedance transformation block by multi-stage stairs shape depression 11, traditional stepped impedance transformation block can be replaced to realize impedance matching.Impedance transformation layer 12 can by process deposits such as sedimentations on the inner surface of multi-stage stairs shape depression 11, and the thickness of impedance transformation layer 12 can be arranged according to actual needs, to be adapted to the insertion size of different coaxial fittings 2.By adding dielectric-slab 3, transmission performance and impedance matching effect can be improved.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.By adding dielectric-slab 5, transmission performance and impedance matching effect can be improved.
