Embodiment 1

[0017] Such as Figure 1-4 As shown, as a preferred embodiment of the present invention, the ridge 5 in the upper ridge waveguide is located on the top wall of the upper ridge waveguide, and the ridge 4 in the lower ridge waveguide is located on the bottom wall of the lower ridge waveguide. The four ends of the I-shaped gap 7 are all provided with rounded corners. The convex ridge 5 of the upper ridge waveguide is integrally connected with the convex short-circuit surface 6 , and the connection between the convex ridge 5 and the convex short-circuit surface 6 adopts a round transition.

Abstract

The invention belongs to the field of microwave technology, and in particular relates to a ridge waveguide power divider, which includes an upper ridge waveguide and a lower ridge waveguide. The I-shaped gaps of the upper and lower ridge waveguides, one end of the upper ridge waveguide is closed, the other end constitutes the general port of the ridge waveguide power divider, and the two ends of the lower ridge waveguide power divider constitute the two ends of the ridge waveguide power divider. A sub-port; the inside of the closed end of the upper ridge waveguide is provided with a convex short-circuit surface, and the outline of the short-circuit surface is flush with the U-shaped edge on one side of the I-shaped gap. In the present invention, the short-circuit surface is set in a convex shape matching the I-shaped gap, which not only meets the power division and circuit matching requirements of the power divider, but also shortens the short-circuit surface and overall length of the power divider.

Description

technical field [0001] The invention belongs to the field of microwave technology, and in particular relates to a ridge waveguide power divider. Background technique [0002] The single-ridge waveguide slot antenna is an antenna suitable for working in the high-frequency band. It has the advantages of low loss and high reliability, and can be used in land, sea, air, sky and other environments. Ridge waveguide broadside coupled power divider is the main method to realize the feeding of ridge waveguide slot antenna. There is a three-port power splitter in the prior art, which mainly couples the power of the upper ridge waveguide to the lower ridge waveguide by opening a "one" or "I" slit on the common waveguide wall, usually at the distance coupling slit There is a ridge waveguide transmission line and a short-circuit plane for matching, where the length of the transmission line is about half of the wavelength of the ridge waveguide. The disadvantage of this power splitter i...
