Embodiment 1
[0029] Such as figure 1 shown.
[0030] A symmetrical microwave coupling structure that connects two spaces along the Z axis. The microwave channel consists of a branch. The branch is composed of nine through holes 31 communicating along the Y direction.
[0031] The maximum length t of the microwave channel is less than 0.2 times the wavelength in free space corresponding to the central operating frequency of the microwave channel.

Abstract
The invention discloses a symmetrical microwave coupling structure. A plurality of rectangular or through holes of other shapes are communicated with each other to form a microwave channel to be matched with various microwave circuits or to be communicated with various microwave areas. The microwave channel is in mirror symmetry. Compared with existing similar schemes, the modeling optimization calculation efficiency can be remarkably improved. The microwave circuit is smaller in size and wider in working bandwidth. Particularly, different transmission lines can be matched in an ultra-widebandfrequency range and comprise a coaxial line, a rectangular waveguide, a circular waveguide, a rectangular waveguide or a circular waveguide with a ridge, and an SIW (substrate integrated waveguide),a micro-strip, a strip line and the like. The invention can also be used for matching transmission lines having perpendicular or reversed axial lines and also used for matching different kinds of transmission lines twisting in different angles around the axial lines. The system is mainly used in communication and radar systems of microwave, millimeter wave and terahertz wave bands.
Description
technical field [0001] The invention relates to a microwave component, in particular to a compact matching coupling structure for broadband matching of various transmission lines and other microwave structures, and a microwave coupling structure for effectively connecting two spaces. Background technique [0002] In various microwave systems, the matching problem of transmission lines is common. This is because the primary function of any microwave transmission line is to transfer as much microwave energy as possible to the intended device. To achieve this, various matching circuits and mode converters are required depending on the input impedance of the target device and the operating mode. [0003] The existing matching circuits and mode converters are complex in structure, large in size and narrow in bandwidth, especially in coaxial lines and waveguide circuits. [0004] On the other hand, microwave coupling structures connecting two spaces are ubiquitous. The shape of...
