Abstract

The invention discloses a step transition of a rectangular waveguide transmission line, which comprises an input transmission line, an output transmission line and at least one electromagnetic channel. The two end surfaces of the electromagnetic channel are part of a plane A and a plane B respectively. The plane A is parallel to the plane B. The input transmission line and the output transmissionline are respectively communicated with one of the two end faces of the electromagnetic channel through one cross section. The input transmission line and the output transmission line are different insize. The input transmission line is a rectangular waveguide. The electromagnetic channel is composed of at least one branch, and at least one electromagnetic wave branch is composed of at least three through holes which are communicated along the Y direction. The transmission line step transition can achieve broadband compact matching transition between transmission lines of different sizes. Thesystem is mainly applied to various communication and radar systems of microwave, millimeter wave and terahertz wave bands.

Description

technical field [0001] The present invention relates to an electromagnetic wave element, in particular to an electromagnetic wave structure that enables a transmission line to be matched and communicated with another transmission line with a different size within a very short distance. Background technique [0002] In various electromagnetic wave systems, connections between similar transmission lines of different sizes are ubiquitous. Signals in the transmission line will be reflected due to the parasitic effects of the discontinuity at the connection. In order to realize the matching of the step transition of the transmission lines, it is necessary to set a matching structure between the transmission lines. [0003] The existing matching circuit has complex structure, large volume, and narrow bandwidth, especially in rectangular waveguides, single-ridge rectangular waveguides, double-ridge rectangular waveguides and four-ridge rectangular waveguides, circular waveguides o...
