Specific embodiment
The preferred embodiment of utility model is provided, with reference to the accompanying drawing the technical solution of the utility model is described in detail.
Here, respective drawings will be provided the utility model is described in detail.It should be strongly noted that as described herein preferred
Examples of implementation are only used for describing and explaining the present invention, and are not limited to or limit the utility model.
As shown in Figure 1, a kind of dual polarization combiner, including main waveguide 1, dual polarization separation with dual polarized signals channel
Device 4 and two complementary waves with single-polarized signal channel lead 2,3, and the Single port that two complementary waves lead 2,3 divides with dual polarization respectively
A port connection from device 4, two complementary waves are led 2,3 and are coupled by coupled structure with main waveguide 1.
As shown in Figure 1, 2, there are two ports, i.e. I 1-1 of port and ports port II for main waveguide tool, when one of port
As input port, another is divided into dual polarization separator, dual polarization point i.e. as port is brought out inside the circle in Fig. 2
Dual polarized signals are separated into horizontal and vertical polarized two orthogonal single modes from device 4, and are led and main wave by two complementary waves
1 two perpendicular end couplings are led, it is two-way that two complementary waves, which lead 2,3,.
The course of work of combiner is as follows:
Dual polarized signals enter bipolar separator by V 4-1 of port, and 4 two transmission ports of bipolar separator will be bipolar
Change Signal separator be horizontal polarization and vertical polarization respectively enter complementary wave lead 2 and complementary wave lead 3, using I 1-1 of port as input terminal
Mouth, II 1-2 of port couple to form orthogonal vertical pair with the horizontal polarization and vertical polarization for entering main waveguide 1 as output port
Polarized signal, conversely, using II 1-2 of port as input port, it is defeated by V 4-1 of port and I 1-1 of port to information contrary operation
Out.
To meet machining, main waveguide 1 and complementary wave are preferably led 2,3 for square wave guide, in addition to the portion of coupled structure connection
Divide except the part being connect with bipolar separator, circle can be designed as according to present position and simulation result.
The coupled structure is that slot-coupled or cylinder couple.Optimal selection slot-coupled, complementary wave lead 3 as ladder mistake
Degree, is designed by electromagnetic simulation software, easy to process.
To realize laser propagation effect, the length that two complementary waves lead 2,3 exceeds coupled structure present position a part, meanwhile,
To prevent redundant electromagnetic wave from interfering, two complementary waves, which lead to be equipped in one end port that 2,3 do not connect with bipolar separator 4, inhales wave material
Material 5 is finally integrally formed only there are three dual-polarized port, i.e. III 2-1 of port and IV 3-1 of port are built-in with absorbing material, inhale
Wave material absorbs extra electromagnetic wave, and absorbing material 5 is apart from coupled structure 4-6mm.
As shown in Figure 5,6, in the case where II 1-2 of port is placed and loaded, S11 and S22 are respectively I 1-1 of port and port
The return loss of V two ports 4-1, what two Zhang Tu were represented is different polarization, and Fig. 5 is not same polarization, and Fig. 6 is identical polarization,
S21 refers to the isolation of V two ports 4-1 I 1-1 of port and port.No matter that polarization mode of port, two ports
Isolation be both greater than 20, and echo is greater than -14dB.
The above is only the preferred embodiment of the utility model, the utility model is not limited to or limited.For this
For the research in field or technical staff, various modifications and changes may be made to the present invention.All spirit in the utility model
Within principle, any modification, equivalent replacement, improvement and so on should be included in the protection model that the utility model is stated
Within enclosing.
