Embodiment Construction

[0022] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0023] Such as figure 1 and 2 , a full-bandwidth rectangular waveguide coaxial conversion device, can be applied to a rectangular waveguide 1, the front end of the rectangular waveguide 1 has an opening 7, and the back is a cut-off wall 6, so that electromagnetic waves can only propagate in the direction of the opening 7.

[0024] This patented technology can be applied to the rectangular waveguide 1 with a cross-sectional width of 149.9 / fc (fc is the cut-off frequency of the rectangular waveguide), and the inner cross-sectional height of the rectangular waveguide 1 is less than or equal to 0.7 times the inner cross-sectional width of the rectangular waveguide 1 , the internal section refers to the section of the inner cavity of the rectangular waveguide 1 in a plane perpendicular to the front-to-back direction. Preferably, the rectangular waveguide 1...

Abstract

The invention discloses a full-bandwidth rectangular waveguide coaxial conversion device. The device comprises a rectangular waveguide body. An opening is arranged in the front end of the rectangularwaveguide body, and the back is a cut-off wall. The device is provided with a coaxial connector. The metal inner shaft of the coaxial connector is connected with a metal probe in the rectangular waveguide body from the outer side of the bottom of the rectangular waveguide body. The outer side of the probe is coated with a non-metal dielectric layer. The non-metal dielectric layer is made of polytetrafluoroethylene. A metal body perpendicularly connected with the bottom wall of an inner cavity is arranged in the cavity of the rectangular waveguide body. The metal body is located on the front side of the probe. According to the invention, the reflection coefficient of the full waveguide bandwidth is greatly reduced; the insertion loss is effectively reduced; the conversion efficiency is improved; the effect is stable; and due to simple structure and easy processing and molding, the device can be widely used in a rectangular waveguide wave tube technology in the field of microwave communication in a standardized way and in a full-bandwidth spectral range.

Description

technical field [0001] The invention relates to a rectangular waveguide coaxial conversion device in the field of microwave communication. Background technique [0002] Waveguides are widely used in the field of microwave communications. According to their cross-sectional shapes, they can be divided into rectangular waveguides, circular waveguides, double-ridge waveguides, and elliptical waveguides. In view of the characteristics of good electromagnetic shielding and low loss, waveguides are often used in long-distance microwave transmission equipment. The rectangular waveguide is widely used in satellite communication because of its simple structure. In the equipment in the field of interference and anti-interference communication, rectangular waveguides are often used as input / output ports, while feeder cables, vector analyzers, spectrum analyzers, power amplifiers, etc. in actual engineering also use coaxial cables as input / output ports. output port. Rectangular wavegu...
