Abstract
The utility model discloses a polarization separator which is characterized in that the polarization separator adopts round waveguide or square waveguide as main transmission waveguide; and through the fine design, an over-mode structure is led in by a port coupled through a side opening so as to achieve the polarization separator which is inconsistent with the traditional design. The good electrical performance of the polarization separator can be completely obtained; and with the structure, the processing of devices of the type can be greatly simplified, the reliability and consistency of products can be improved, the cost is low, and the batch production of the products can be extremely facilitated, so that the polarization separator has good promotion value.
Description
Technical field
The utility model relates to microwave antenna and microwave device technical field, relates to the linear polarization Signal Separation of two quadratures that microwave antenna receives in particular or launches the combination mechanism of the linear polarization signal of two quadratures.
Background technology
The main effect of polarization separator is with being fed in the same antenna of the identical linear polarization microwave signal of two-way operating frequency quadrature, or the Signal Separation of the quadrature linear polarization that same antenna is received becomes two microwave signals.Owing to have higher isolation between the polarization separator two-port, so the signal of this two-port can non-interferingly transmit.Its use can increase the information capacity of microwave transmission system, improves the utilization rate of shared channel.
General polarization separator structure has following two kinds of versions: as shown in Figure 1 and Figure 2, include three ports and one transmission leading body, a common port A, two polarization port ones, 2 and transmission leading body B.Need to exist simultaneously two mutually orthogonal electric fields owing in the leading body of this polarization separator, the waveguide that the interior cross section of therefore general employing is a circle is as the main waveguide of transmission.And, can between polarization port one, 2, add the metal polarization rotation pin that a sheet metal----polarization decoupling sheet or rotary polarization are used usually in order to reach the requirement of low standing-wave ratio high-isolation.There is following shortcoming in above dual mode: 1, product structure complexity, and technology difficulty is big, is unfavorable for processing; 2, there is destabilizing factor in product, poor reliability; Consistency of product is poor, is not suitable for producing in batches.
Summary of the invention
The purpose of this utility model is exactly a kind of structure of not only simplifying polarization separator that provides for the deficiency that solves prior art, guarantee the reliability of this device and the consistent type of product, and can improve the polarization separator of the speed of production and the efficient of product greatly.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of polarization separator, comprise the main waveguide of transmission and go up a polarization port and a shared port that is provided with, it is characterized in that, described polarization port is mutual vertical-type structure, be divided into the sidepiece and the end of the main waveguide of transmission, the port of side mouth coupling was introduced mode configuration.
As further specifying of such scheme, described common port is on the same axis with the polarization port that is positioned at the main waveguide end of transmission, port and this axis normal of the coupling of side mouth.
The main waveguide of described transmission adopts square waveguide or circular waveguide as the main waveguide of transmission.
The main waveguide of described transmission processes by machinery integral with aluminium or other metal bar.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts circular waveguide or square waveguide as the main mould of transmission, its two output port also is mutual vertical-type structure, but improve and introduced by the structure of counter-lateral quadrents port pattern the structure optimization port coupling and reduce crosstalking mutually between the two-port, thereby under the prerequisite that satisfies the polarization separator performance, removed because the destabilizing factor that traditional structure produced, the realizability of the product of Ti Gaoing and reliability of products, consistency greatly.

Embodiment
As shown in Figure 3 and Figure 4, a kind of polarization separator of the utility model, comprise the main waveguide 3 of transmission and go up the polarization port 4 that is provided with, 5 and one shared port 6, parabolic antenna 7 is sheathed on outside the common port 6, polarization port 4, the 5th, mutual vertical-type structure, be divided into the sidepiece and the end of the main waveguide 3 of transmission, the port of side mouth coupling was introduced mode configuration, can be with being fed in the same antenna of the identical linear polarization microwave signal of two-way operating frequency quadrature, or the Signal Separation of the quadrature linear polarization that same antenna is received becomes two microwave signals.Wherein, transmitting main waveguide can adopt circular waveguide also can adopt square waveguide as the main waveguide of transmission as the main waveguide of transmission; Can process by machinery integral with aluminium or other metal bar, also can form by hot investment casting.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
