Abstract

The invention discloses a broadband mode converter from a rectangular waveguide TE10 mode to a circular waveguide TE02 mode, and belongs to the technical field of microwave and millimeter wave devices. The design route adopted by the invention is the standard rectangular waveguide TE10 mode, a rectangular waveguide TE20 mode, a rectangular waveguide TE40 mode, a cross-shaped waveguide TE44 mode, across-shaped fan-shaped waveguide TE44 mode and the circular waveguide TE02 mode. According to the broadband mode converter from the rectangular waveguide TE10 mode to the circular waveguide TE02 mode, by changing the external shape of a waveguide, the boundary condition when an electromagnetic wave is propagated in the waveguide is changed, and the broadband mode conversion from the rectangularwaveguide TE10 mode of a linear gradient structure to the circular waveguide TE02 mode is realized by means of a transfer mode scheme. According to the mode converter, the problems of low mode conversion efficiency and narrower bandwidth are effectively solved, and each mode conversion section is of a linear gradient structure, so that the mode converter is simple in structure and high in practicability, and is convenient to process.

Description

technical field [0001] The invention belongs to the technical field of microwave and millimeter wave devices, and in particular relates to a novel broadband rectangular waveguide TE 10 to circular waveguide TE 02 wideband mode converter. Background technique [0002] Mode converter is a microwave passive device widely used in satellite communication, spaceborne radar, microwave measurement, microwave power synthesis and other fields. In the study of gyrotrons, due to the adoption of high-order modes, the conversion between different modes has become an important means of mode selection and suppression as well as electromagnetic wave input and output coupling, and many types of mode conversions are derived according to the differences in the application purposes of mode converters. device. Traditional rectangular waveguide TE 10 Mode to Circular Waveguide TE 02 The main design route of the mode converter is: rectangular waveguide TE 10 mode conversion to coaxial wavegui...
