The content of description is illustrative and be not restrictive, and should not be limited the scope of the invention with this.
As shown in Figure 1, disclosing a kind of circular polarisation TE in one embodiment of the invention21Mode coupler structure, it is described
Coupler structure includes: circular waveguide cavity 1, rectangular waveguide cover board 2 and first flange disk 3.The circular waveguide cavity 1 is cylindrical shape
Structure is circumferentially uniformly provided with multiple rectangular recess 5, circular waveguide chamber described in the long edge of the rectangular recess 5 along its outer surface
1 axial direction of body opens up.Each rectangular recess 5 is equipped with and the one-to-one rectangular waveguide of the rectangular recess 5
Cover board 2, it is preferable that the rectangular waveguide cover board 2 is connected with the circular waveguide cavity 1.By the rectangular waveguide cover board 2 with
After rectangular recess 5 on the circular waveguide cavity 1 is fixedly connected, rectangular waveguide cavity body structure is formed;The rectangular waveguide cover board 2
Both ends be respectively equipped with a rectangular waveguide square opening, the square opening is connect by rectangular tube with the first flange disk 3, formation one
A rectangle communicating passage, whole U-shaped channel design.It is opened respectively with the rectangular waveguide cover board both ends one end of the rectangular tube
If rectangular waveguide square opening be fixedly connected;The other end of the rectangular tube is fixedly connected on the first flange disk.Pass through setting
The first flange disk 3 is convenient for docking other structures.
In the present embodiment, as shown in Figure 2, it is preferable that the uniform cloth in circumferentially outer surface of the circular waveguide cavity 1 is in total
Eight edge rectangular recess parallel with the axial direction of circular waveguide cavity 15 are offered, make the rectangular waveguide channel to be formed about institute
It states circular waveguide cavity 1 to be symmetric, each rectangular recess 5 is corresponded with the rectangular waveguide cover board 2.Meanwhile
5 bottom of rectangular recess is uniformly distributed multiple circular holes 6, it is preferable that in 5 bottom of rectangular recess from centre to circular waveguide
The diameter for the circular hole 6 that the direction of both ends of cavity is laid successively decreases setting.The transformation of the circular hole number and diameter can root simultaneously
Depending on microwave frequency.
In the present embodiment, rectangular waveguide cavity is avoided existing due to being the arrangement for being covered plate using groove
Have need to be processed into it mutually matched globoidal structure in technology and caused by the big difficulty of difficulty of processing.Further, described
The both ends of rectangular recess 5 are equipped with rectangular step 7.Groove is formd by bottom to top it is ladder-like, and it is indirect be processed into it is straight
