Abstract
The invention discloses a rectangular waveguide-to-coaxial converter. The converter comprises a dielectric substrate, a first metal layer, a second metal layer and a coaxial connector. The coaxial connector is vertically coupled to the surface of the dielectric substrate, the lower surface of the dielectric substrate is connected with a first port of the rectangular waveguide and is perpendicular to the metal wall of the rectangular waveguide, the first metal layer is attached to the upper surface of the dielectric substrate, and the second metal layer is attached to the lower surface of the dielectric substrate. When a rectangular waveguide port is connected, only the dielectric substrate needs to be attached to the rectangular waveguide port to be connected, and meanwhile, a coaxial line is inserted into the dielectric substrate to be connected with the first metal layer and the second metal layer so that assembly is completed. A rectangular waveguide port does not need to be processed, and the coaxial line can be conveniently and rapidly connected with various devices and instruments. The converter can be widely applied to a microwave system, and the rectangular waveguide port can be quickly and conveniently converted into the coaxial line to be used for cascading work between the system and devices.
Description
technical field [0001] The invention relates to the technical field of microwave / millimeter wave energy transmission, in particular to a rectangular waveguide-to-coaxial converter. Background technique [0002] Today, with the rapid development of electronic system research and development and production, rectangular waveguides are widely used in electronic systems due to their good electromagnetic shielding and low loss characteristics. Feed cables, vector analyzers, and spectrum analyzers in actual engineering use coaxial cables as input / output wide ports. Therefore, a device with a waveguide structure as an output port needs a complicated connection device to work during testing and maintenance. The waveguide-to-coaxial converter is widely used as a conversion device from waveguide to coaxial line. [0003] Existing waveguide coaxial conversion devices require additional processing of the original rectangular waveguide. Insert the coupling probe deep into the rectangul...
