Embodiment Construction

[0024] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0025] Such as figure 1 As shown, one embodiment of the present invention discloses a circularly polarized TE 21 A mode coupler structure, the coupler structure includes: a circular waveguide cavity 1 , a rectangular waveguide cover plate 2 and a first flange 3 . The circular waveguide cavity 1 is a cylindrical structure, and a plurality of rectangular grooves 5 are evenly formed along the circumference of its outer surface, and the long sides of the rectangular grooves 5 are formed along the axial direction of the circul...

Abstract

The invention discloses a circularly polarized TE21 mode coupler structure. The structure comprises a circular waveguide cavity with a rectangular groove on the outer surface in the radial direction,a rectangular waveguide cover plate covered on the rectangular groove, and first flanges fixedly connected to the two ends of the rectangular waveguide cover plate. The circularly polarized TE21 modecoupler structure provided by the invention reduces the processing difficulty of the circular waveguide cavity structure and improves the product qualification ratio of the coupler structure.

Description

technical field [0001] The invention relates to electrical components, in particular to a circularly polarized TE 21 mode coupler structure. Background technique [0002] Couplers are important devices in microwave transmission lines, and their common forms include microstrip structures and waveguide structures. Due to the large number of feeding channels of a certain feed source and the strict requirements on the size of the feed source, a highly integrated coupler structure in the form of a waveguide is selected; Split at the place, and the two ends of the rectangular waveguide cavity are designed as arc transitions, the mechanical processing of the entire coupler is difficult, and the product qualification rate is low. [0003] In view of the above-mentioned problems existing in existing solutions, the present invention is proposed. Contents of the invention [0004] The object of the present invention is to provide a circularly polarized TE 21 The mode coupler stru...
