Abstract

The invention discloses a rectangular waveguide staggered transmission line, and the transmission line comprises at least two input transmission lines and at least one electromagnetic channel. The twotransmission lines are each communicated with one of the two end faces of the electromagnetic channel through one end face thereof. The two transmission lines are staggered in the direction of lateral faces of the transmission lines. At least one of the two transmission lines is a rectangular waveguide. The electromagnetic channel consists of at least one branch. At least one of the branches is formed by at least three through holes which are communicated in the Y direction. The staggered transmission line can achieve the wideband compact staggered transition of various waveguides, ridge waveguides, and multi-ridge waveguides. The transmission line is mainly used in various communication and radar systems of microwaves, millimeter waves and terahertz bands.

Description

technical field [0001] The present invention relates to an electromagnetic wave element, in particular to a compact electromagnetic wave structure in which one transmission line communicates with another transmission line in dislocation matching. Background technique [0002] In various electromagnetic wave systems, dislocation connections between transmission lines are ubiquitous. The signal in the transmission line will be reflected due to the parasitic effect of the discontinuity at the dislocation. In order to realize the matching of the dislocation transmission line, it is necessary to set a matching circuit on the transmission line. [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 or elliptical waveguides, single-ridge circular waveguides or elliptical ...
