Abstract
The invention discloses a rectangular waveguide-to-coaxial converter. The converter includes a dielectric substrate, a first metal layer, a second metal layer, and a coaxial connector. Wherein, the coaxial connector is vertically coupled to the surface of the dielectric substrate, the lower surface of the dielectric substrate is connected to the first port of the rectangular waveguide and is perpendicular to the metal wall of the rectangular waveguide, and the first metal layer is bonded to the The upper surface of the dielectric substrate, the second metal layer is bonded to the lower surface of the dielectric substrate. When connecting the rectangular waveguide port, it is only necessary to attach the dielectric substrate to the rectangular waveguide port to be connected, and at the same time insert the coaxial cable into the dielectric substrate to connect with the first metal layer and the second metal layer, and the assembly is completed. There is no need to process the rectangular waveguide port, and the coaxial line can be conveniently and quickly connected to various devices and instruments. The invention can be widely used in microwave systems, quickly and conveniently converts rectangular waveguide ports into coaxial lines, and is responsible for the cascading work between systems 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...
