Abstract

The invention discloses a combined waveguide. The combined waveguide is formed by a gap waveguide and a rectangular waveguide in a horizontal or vertical transferring mode, or the combined waveguide is formed by a gap waveguide and a micro-strip line in a horizontal transferring mode. According to the combined waveguide, the effect of connecting and matching of the gap waveguide and the rectangular waveguide or the micro-strip line in the transferring process is achieved, and the gap waveguide can be applied to an existing high-frequency circuit structure; in comparison with the mode of adopting a traditional transmitting line, the loss of a system can be reduced, the transmitting efficiency is improved, the processing difficulty of a circuit is lowered, the processing cost is reduced, and the insertion loss of the system is reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a combined waveguide. Background technique [0002] Electronic devices are now widely used for the transmission of various signals, which are divided into high-frequency signals and low-frequency signals. For the transmission carriers of these signals, low-frequency signals are usually transmitted in the form of wires and cables, and high-frequency signals are mainly transmitted in the form of radio waves. For high-frequency signals, the transmission hardware includes both high-frequency transmission lines and low-frequency transmission lines. High-frequency transmission lines are used to transmit and receive radio waves, and low-frequency transmission lines are used to transmit sound or video information that needs to be modulated. Traditional high frequency transmission lines include: rectangular waveguide, microstrip line. [0003] With the development of communication...
