Abstract
The utility model discloses an L-type waveguide rotating joint, comprising a first flange plate (1), a first rectangular waveguide (2), an annular waveguide (3), a second rectangular waveguide (4), and a second flange plate (5), which are sequentially connected. The first flange plate (1) is mounted on the first rectangular waveguide (2), while the second flange plate (5) is mounted on the second rectangular waveguide (4). The annular waveguide (3) is arranged between the first rectangular waveguide (2) and the second rectangular waveguide (4). The first rectangular waveguide (2), the annular waveguide (3), and the second rectangular waveguide (4) are L-shaped as a whole. The beneficial effects of the utility model are that the second rectangular waveguide can rotate with respect to the first rectangular waveguide, so that the signal power loss during the process that electromagnetic waves are transmitted in the waveguide can be reduced; and the first rectangular waveguide and the second rectangular waveguide employ the impedance matched annular waveguide for connection, so that the return loss index of the electromagnetic waves is increased and the signal power loss of the electromagnetic waves is further reduced.
Description
Technical field
The utility model relates to Electromagnetic Wave Propagation technology, particularly a kind of L-type waveguide junction.
Background technology
Microwave rotary joint is the necessary element that guarantees the normal operation of microwave rotable antenna, in the situation that microwave does not stop rotation, microwave signal is transferred to antenna from transmitter, and flows to receiver from antenna, realizes orientation and faces upward the search of bowing.Waveguide is in microwave rotary joint, to be used for the critical component of guide electromagnetic waves.Generally mention waveguide and just refer to hollow metal tube.According to the difference of waveguide cross sectional shape, can be divided into rectangular waveguide and circular waveguide, although there are a lot of different waveguide forms, and new form also constantly occurs, waveguide tube wall generally adopts the metals such as copper aluminium to make, sometimes inwall is also coated with silver or gold, its resistivity is very high, air meson in waveguide is exactly the passage of electromagnetic transmission, referred to as channel, the propagation of electromagnetic wave in class of waveguide channels is subject to the hindrance functions such as the restriction of waveguide inwall and reflection, causes that impedance matching is poor, return loss index error, and signal power loss is large.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and the L-type waveguide junction that a kind of signal power loss is low is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of L-type waveguide junction, it comprises the ring flange one connecting successively, rectangular waveguide one, disc waveguide, rectangular waveguide two and ring flange two, it is characterized in that: ring flange one is arranged on rectangular waveguide one, ring flange two is arranged on rectangular waveguide two, disc waveguide is arranged between rectangular waveguide one and rectangular waveguide two, rectangular waveguide one is horizontally disposed with, rectangular waveguide two arranges perpendicular to rectangular waveguide two, and rectangular waveguide one, disc waveguide and rectangular waveguide two are whole L-shaped.
Described ring flange one is arranged on the left end of rectangular waveguide one, and ring flange two is arranged on the top of rectangular waveguide two.
The utlity model has following advantage: (1) rectangular waveguide two of the present utility model relatively rectangular waveguide one rotates, thereby reduce electromagnetic wave communication process signal power loss in this waveguide.(2) rectangular waveguide one and rectangular waveguide two adopt impedance matchings disc waveguide be connected, thereby improved electromagnetic return loss index, further reduced the loss of electromagnetic wave signal power.(3) on an end face of rectangular waveguide one and rectangular waveguide two, be separately installed with ring flange one and ring flange two, easy for installation, easy to manufacture, electrical connection properties obviously improves simultaneously.

Fig. 2 is vertical view of the present utility model;
Fig. 3 is that the A of Fig. 1 is to view;
In figure, 1-ring flange one, 2-rectangular waveguide one, 3-disc waveguide, 4-rectangular waveguide two, 5-ring flange two.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, protection range of the present utility model is not limited to the following stated:
As depicted in figs. 1 and 2, a kind of L-type waveguide junction, it comprises the ring flange 1 connecting successively, rectangular waveguide 1, disc waveguide 3, rectangular waveguide 24 and ring flange 25, ring flange 1 is arranged on rectangular waveguide 1, ring flange 25 is arranged on rectangular waveguide 24, disc waveguide 3 is arranged between rectangular waveguide 1 and rectangular waveguide 24, one side of disc waveguide 3 is connected with the side of rectangular waveguide 1, the opposite side of disc waveguide 3 is connected with rectangular waveguide 24 end faces, rectangular waveguide 1 is horizontally disposed with, rectangular waveguide 24 arranges perpendicular to rectangular waveguide 24, rectangular waveguide 1, disc waveguide 3 and rectangular waveguide 24 are whole L-shaped.
As depicted in figs. 1 and 2, ring flange 1 is arranged on the left end of rectangular waveguide 1, and ring flange 25 is arranged on the top of rectangular waveguide 24.As shown in figures 1 and 3, the inside and outside all rectangular shapes of rectangular waveguide 1 and rectangular waveguide 24, vertically the direction of arrow is electromagnetic Way in, first electromagnetic wave enters in rectangular waveguide 24, rectangular waveguide 24 is done rotatablely moving of 360 degree with respect to rectangular waveguide 1, then electromagnetic wave spreads out of through the left port of rectangular waveguide 1, due to rectangular waveguide 1 and rectangular waveguide 24 adopt impedance matchings disc waveguide 3 be connected, thereby improved electromagnetic return loss index, reduced the loss of electromagnetic wave signal power.On one end face of rectangular waveguide 1 and rectangular waveguide 24, be separately installed with ring flange 1 and ring flange 25, make L-type waveguide junction easy for installation, easy to manufacture, obviously improved electrical connectivity simultaneously.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also do some improvement and replacement, these improvement and replacement also should be considered as protection range of the present utility model.
