Abstract
The utility model discloses a separating polarization separator comprising a transmission port, a vertical port and a horizontal port. The vertical port is realized by the transformation of waveguide from the transmission port along a direct-connection direction through several sections of rectangular waveguide ladders, and the horizontal port is realized by the coupling of waveguide from the transmission port through a waveguide side port. The separating polarization separator has a compact inside structure without any matching and adjusting mechanism, and a typical structure is mechanically processed integrally without assembling or debugging.
Description
Technical field
The utility model relates to microwave antenna and microwave passive component technical field, and is particularly a kind of with the linear polarization Signal Separation of two quadratures or synthetic separate type polarization separator.
Background technology
In recent years; Development along with the microwave communication technology; Microwave antenna and microwave passive component technology have also obtained significant progress, and performance still is that version is all developing towards better direction, to satisfy the social demand and the fierce competitive market of constantly development.
Polarization separator is because two polarization ports exist higher isolation, thereby the signal of two ports can non-interferingly transmit, and the application of polarization separator can increase the information capacity of microwave transmission system, improves the utilization rate of shared channel.
Polarization separator is on the one hand as a kind of independent microwave passive component, in microwave transmission system other equipment of neutralization and the supporting use of device.On the other hand, polarization separator is the important component part of dual polarization microwave antenna.
The polarization separator of traditional dual polarized antenna is often inner at microwave antenna, its complex structure, and difficulty of processing is big; Consistency is poor, and cost is high, and isolation neither be very desirable; Along with the development of microwave technology, polarization separator is set at the outside of microwave antenna, though aspects such as structure and technology all make moderate progress; But still can not satisfy the demand, the name of the game is not resolved.What need in the market is simple in structure, and technology difficulty is little, and production procedure is few, good reliability, and rate of finished products is high, excellent electrical properties, good looking appearance, the polarization separator that cost is low.
Summary of the invention
In order better to tackle fierce competitive market, in order to strengthen core competence of enterprises, to the defective or the deficiency of above-mentioned conventional polar separator existence; The purpose of the utility model just provides a kind of simple in structure, and technology difficulty is little, and production procedure is few; Good reliability, rate of finished products is high, excellent electrical properties; Good looking appearance, the polarization separator that satisfies market demand that cost is low.
To achieve these goals, the utility model adopts following technical solution:
A kind of separate type polarization separator; Comprise transmit port, vertical port and three ports of horizontal port; Described vertical port is connected with transmit port through multistage rectangular waveguide ladder, and horizontal port is connected with transmit port through multistage rectangular waveguide ladder and waveguide side mouth successively.
The present invention also has following other technologies characteristics:
Described transmit port and the coaxial setting of vertical port, transmit port place axis is vertical each other with horizontal port place axis normal.
The cross section of described transmit port is the square of band fillet, and the cross section of described vertical port and horizontal port is the rectangle of band fillet.
Described transmit port, vertical port and the outside, three ports of horizontal port all be provided with a plurality of screwed holes, in order to test or to be connected with other devices.
The utility model compared with prior art has following technological beneficial effect:
The utility model adopts the non-standard square wave guide of band fillet as transmission waveguide; Vertical port is realized through a few joint rectangular waveguide step conversion along straight-through direction by the waveguide from the transmission port; Horizontal port by from the waveguide of transmission ends through the side mouth waveguide realization that directly is coupled, saved that the accent in the traditional structure is surveyed and coupling mechanism, whole polarization separator one processes; Technological forming is simple; Internal structure is also very simple, and having removed influences its stable factor, has improved reliability of products and consistency greatly.The utility model is transferred links such as survey owing to saved assembling, and the small and exquisite again cost that greatly reduces product of volume is simultaneously through multistage step conversion has strengthened electric properties such as isolation, standing-wave ratio to its internal implementation.
Description of drawings
Fig. 1 is the sectional structure sketch map of the utility model.
Fig. 2 is the Facad structure sketch map of the utility model.
Fig. 3 is the structural representation that the utility model and microwave antenna assembling back constitute dual polarized antenna.
Below in conjunction with accompanying drawing the particular content of the utility model is done further explain.
Embodiment
Like Fig. 1-shown in Figure 3; The separate type polarization separator of the utility model; Comprise transmit port 1, vertical port 2 and 3 three ports of horizontal port; Described vertical port 2 is connected with transmit port 1 through multistage rectangular waveguide ladder, and vertical port 2 is realized through a few joint rectangular waveguide step conversion along straight-through direction by the waveguide from the transmission port one.Horizontal port 3 is connected with transmit port 1 through multistage rectangular waveguide ladder and waveguide side mouth 4 successively, and horizontal port 3 is realized through 4 couplings of waveguide side mouth by the waveguide from the transmission ends port one.Transmit port 1 and vertical port 2 coaxial settings, transmit port 1 place axis is vertical each other with horizontal port 3 place axis normal, and its internal structure is compact, does not have any coupling and governor motion.
Preferably, the cross section of transmit port 1 is the square of band fillet, and vertical port 2 is the rectangle of band fillet with the cross section of horizontal port 3.The square or the rectangle of band fillet are not to be square or circular simple deformation, and its pattern as the transmission waveguide transmission is more complicated, and the advantage of selecting the waveguide of this shape for use is to improve the electric property of the utility model.
Transmit port 1, vertical port 2 and the outside, 3 three ports of horizontal port all be provided with a plurality of screwed holes, in order to test or to be connected with other devices.
The whole parts of the utility model are that aluminium or copper material or other metals process.The structure of the utility model is that integral body processes, and also assembles after the split processing as required again.
As shown in Figure 3, the utility model and a kind of microwave reflector antenna 5 then constitute the dual polarization microwave antenna when fitting together.
The above-mentioned those of ordinary skill understanding and application the utility model that can help this technical field that the utility model is described.Can easily make modification to embodiment according to the actual requirements for those of ordinary skill in the art, the General Principle that does not need performing creative labour will explain here is applied among other embodiment.Therefore, the utility model is not limited to above-mentioned embodiment, and those skilled in the art should be within protection scope of the present invention to improvement and modification that the utility model is made according to announcement of the present invention.
