Abstract

The invention discloses an orthogonal mode adaptor. The orthogonal mode adaptor comprises a coupled cavity and a transverse output end. The coupled cavity comprises at least two coupling sections which are communicated from left to right. The coupled cavity is communicated with the transverse output end in the back direction. In all the coupling sections from left to right, the first coupling section is a rectangular body with the axis in the direction from left to right, wherein the difference between the width and the height of the left end face of the first coupling section is smaller than 20%. The upper surfaces of all the coupling sections are flush. Meanwhile, a rectangular longitudinal output end is an external port, and the normal at the center of the external port coincides with the direction of the normal at the center of the cross section of the first coupling section from left to right. The orthogonal mode adaptor has the advantages that the orthogonal mode adaptor can be easily obtained by conducting milling and cutting through a machining center, and the influence of the assembly error of a cover plate and a base on the device performance is small, and the orthogonal mode adaptor can be widely applied to microwaves especially satellite communication systems of millimeter waves and terahertz frequency bands and other communication systems.

Description

technical field [0001] The invention relates to an orthogonal mode adapter. Specifically, it relates to an orthogonal mold adapter which is easy to process and can easily guarantee the processing accuracy. Background technique [0002] Orthogonal Mode Transducer (OMT) is a key component in satellite communication. In the line polarization working mode, the uplink and downlink signals are respectively propagated in a vertically crossed line polarization mode. Ortho-mode converters are three-port devices. According to different polarization directions, the orthogonal mode converter separates uplink and downlink signals, and inputs and outputs from different ports. The traditional orthogonal mold adapter is a three-dimensional device, which is generally produced by open mold casting. This method is costly when the product batches are not large. As the signal frequency increases, especially to the millimeter-wave and terahertz frequency bands, the traditional open-mold cast...
