Abstract
The utility model provides a kind of waveguide junction.Waveguide junction comprises the first ring flange, first rectangular waveguide, disc waveguide, second rectangular waveguide and the second ring flange, first rectangular waveguide is placed with the second rectangular waveguide is mutually vertical, first ring flange is arranged on one end of the first rectangular waveguide, the height of disc waveguide is not less than the height of the first rectangular waveguide, the other end of the first rectangular waveguide is connected with the periphery of disc waveguide, second ring flange is arranged on one end of the second rectangular waveguide, the other end of the second rectangular waveguide is connected with the end face of disc waveguide, and the second rectangular waveguide and disc waveguide are coaxially arranged.By the way, the utility model can shorten the propagation path of electromagnetic wave in class of waveguide channels.
Description
Technical field
The utility model relates to Electromagnetic Wave Propagation technical field, particularly relates to a kind of waveguide junction.
Background technology
In the transmission system of microwave signal, can search in the moment at work, following the tracks of and measurement target to make antenna, often require that antenna azimuth can carry out 360 degree of adjustments, the angle of pitch can carry out the adjustment of ± 90 degree.Therefore waveguide junction must be installed between network and feed, ensure that microwave signal can be transmitted effectively.
Waveguide junction is according to the difference of waveguide sections shape, rectangular waveguide and circular waveguide can be divided into, although there is a lot of different waveguide form, but be all overlapped connection between the composition waveguide of traditional waveguide junction, and this can cause the propagation path of electromagnetic wave in class of waveguide channels longer, thus be easily subject to the hindrance function such as restriction and reflection of waveguide inwall, cause the problems such as impedance matching is poor, return loss index error, and signal power loss is large.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of waveguide junction, can shorten the propagation path of electromagnetic wave in class of waveguide channels.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of waveguide junction, described waveguide junction comprises the first ring flange, first rectangular waveguide, disc waveguide, second rectangular waveguide and the second ring flange, described first rectangular waveguide is placed with described second rectangular waveguide is mutually vertical, described first ring flange is arranged on one end of described first rectangular waveguide, the height of described disc waveguide is not less than the height of described first rectangular waveguide, the other end of described first rectangular waveguide is connected with the periphery of described disc waveguide, described second ring flange is arranged on one end of described second rectangular waveguide, the other end of described second rectangular waveguide is connected with the end face of described disc waveguide, and described second rectangular waveguide and described disc waveguide are coaxially arranged.
Preferably, the height of described disc waveguide equals the height of described first rectangular waveguide.
Preferably, described disc waveguide and described first rectangular waveguide and described second rectangular waveguide are welded to connect.
The beneficial effects of the utility model are: the situation being different from prior art, waveguide junction of the present utility model is by being connected directly between on the periphery of disc waveguide by two rectangular waveguides, another is connected on the end face of disc waveguide, thus the propagation path of electromagnetic wave in class of waveguide channels can be shortened, can impedance matching be improved, reduce signal power loss.
Accompanying drawing explanation
Fig. 1 is the schematic front view of the utility model waveguide junction embodiment.
Fig. 2 is the schematic top plan view of the utility model waveguide junction 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 waveguide junction of the utility model embodiment comprises the first ring flange 1, first rectangular waveguide 2, disc waveguide 3, second rectangular waveguide 4 and the second ring flange 5, first rectangular waveguide 2 is placed with the second rectangular waveguide 4 is mutually vertical, first ring flange 1 is arranged on one end of the first rectangular waveguide 2, the height H 1 of disc waveguide 3 is not less than the height H 2 of the first rectangular waveguide 2, the other end of the first rectangular waveguide 2 is connected with the periphery of disc waveguide 3, second ring flange 5 is arranged on one end of the second rectangular waveguide 4, the other end of the second rectangular waveguide 4 is connected with the end face of disc waveguide 3, and the second rectangular waveguide 4 is coaxially arranged with disc waveguide 3.
In the present embodiment, the height H 1 of disc waveguide 3 equals the height H 2 of the first rectangular waveguide 2.Disc waveguide 3 and the first rectangular waveguide 2 and the second rectangular waveguide 4 are welded to connect.
Wherein, the cross section of the first rectangular waveguide 2 and the second rectangular waveguide 4 is rectangle.First electromagnetic wave enters in the first rectangular waveguide 2, and then the direct periphery from disc waveguide 3 enters disc waveguide 3, is entering the second rectangular waveguide 4 from the upper surface of disc waveguide 3.Because electromagnetic wave does not enter disc waveguide 3 from the bottom of disc waveguide 3, thus shorten electromagnetic transmission path.And disc waveguide 3 can carry out impedance matching, can improve impedance matching, reduce signal power loss.First rectangular waveguide 2 and the second rectangular waveguide 4 are separately installed with the first ring flange 1 and the second ring flange 5, waveguide junction can be facilitated to install fixing.
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.
