[0002] In various radar systems and precision radio frequency microwave signal transmission, transmission lines are required for signal conduction in most scenarios, except for wireless signal transmission, where no transmission lines are needed. Coaxial cables and waveguides are widely used to transmit microwave radio frequency energy. In waveguide transmission, it is often necessary to interconnect two transmission lines, which requires a waveguide-to-coaxial converter.
