Embodiment 1

[0040] like figure 1 shown.

[0041] The upper plane coincident quasi-planar orthogonal mode adapter includes three coupling sections 5, a common terminal 1, a port A2, and a port B3. The normal direction at the center of the common terminal 1 is along the -Z direction. All the coupling sections 5 communicate with each other along the Z direction to form a coupling cavity. Port A2 and port B3 communicate with the coupling cavity through two matching sections 6 respectively. The common end 1 communicates with the coupling cavity through two matching sections 6 .

[0042] The cross-sectional shape of the common end 1 is a square.

[0043] The upper surface coincides with the upper surface of all parts of the quasi-planar orthogonal mode adapter. The upper plane coincident quasi-planar orthogonal mode adapter includes all coupling sections 5, matching sections 6, common terminal 1, port A2 and port B3.

[0044] The included angle between the normal direction at the center ...

Embodiment 2

[0052] like figure 2 shown.

[0053] The only difference from Embodiment 1 is that all the coupling sections 5 and matching sections 6 are rectangular in shape. The cross section of port A2 is rectangular and its width is greater than its height; the cross section of port B3 is rectangular and its width is smaller than its height.

Embodiment 3

[0055] like image 3 shown.

[0056] In this implementation example, on the basis of implementation example 2, several levels of matching sections 6 are added, and the cross-section of 1 is rectangular and is mirror-symmetrical to the left and right with respect to its symmetry plane Q. Two other matching sections 6 are added between the port A2 and the original two matching sections 6, and the width of the cross-section of the port A2 is smaller than its height. At the same time, another three matching sections 6 are added between the port B3 and the original two matching sections 6 . Moreover, the normal direction of the port B3 is turned to the Z-axis direction to be parallel to the normal direction of the port A2. Through proper design, we can make the phase difference between port A2 and port B3 and the common terminal 1 the same or close to the same in the working frequency band.

[0057] The outside of the port A2 and the outside of the port B3 are respectively conne...

Abstract

The invention discloses an upper plane and quasi-plane superposed orthogonal mode transducer. A conventional three-dimensional structure orthogonal mode transducer is converted into a quasi-plane structure by adopting coupling segments and matching segments of different widths and heights. The structure can be divided into two parts of a pedestal and a cover plate of which the bottom part is a plane. All microwave structures are arranged on the pedestal and one-time processing can be completed via a common numerical control milling machine without overturning a processed workpiece. Processing precision of a device can be guaranteed and influence of a contraposition error between the pedestal and the cover plate on performance of the device can be substantially reduced so that the upper plane and quasi-plane superposed orthogonal mode transducer has obvious superiority in the fields of high-frequency millimeter wave and terahertz devices. The upper plane and quasi-plane superposed orthogonal mode transducer can be widely applied to microwave and especially millimeter wave and terahertz frequency band satellite communication and other communication systems.

Description

technical field [0001] The invention relates to an upper plane coincidence quasi-plane orthogonal mode adapter. Specifically, it relates to a quasi-plane orthogonal mold adapter whose upper plane coincides with the upper plane and whose machining accuracy is easy to guarantee. Background technique [0002] Orthogonal Mode Transducer (OMT) is a key component in satellite communication. In the line polarization working mode, the inter-frequency orthogonal mode converter is used to separate the uplink and downlink signals according to the difference of the crossed line polarization. The same-frequency orthogonal mode converter is used to add two signals with the same frequency and perpendicular polarization directions to generate a linearly polarized wave, so as to overcome the problems caused by the rotation of the polarization direction during signal transmission. Ortho-mode converters are three-port devices. The traditional upper-plane coincidence quasi-plane orthogonal m...
