Abstract

The invention discloses a double-ridge integrated substrate gap waveguide, which comprises an upper dielectric plate, a lower dielectric plate and a spacing dielectric plate. A first grounding metal layer is printed on the upper surface of the upper dielectric plate. A first microstrip line is printed on the lower surface of the upper dielectric plate. First metal via holes which are periodicallyarranged are formed in the first microstrip line. First metal patches which are periodically arranged are printed on the two sides of the first microstrip line. A second metal via hole is formed in each first metal patch, and a second metal via hole is formed in each second metal patch. A second grounding metal layer is printed on the lower surface of the lower dielectric plate, and the structureof the upper surface is consistent with that of the lower surface of the upper dielectric plate. According to the invention, lower loss and gating of electromagnetic waves in a TEM mode can be realized.

Description

technical field [0001] The invention relates to the field of waveguide technology, in particular to a double-ridge integrated substrate gap waveguide. Background technique [0002] Rectangular waveguide and microstrip circuit are commonly used devices for transmitting electromagnetic waves. Rectangular waveguide has low loss, and microstrip circuit is cheap and easy to manufacture and has great flexibility. It is widely used in communication systems. However, both the rectangular waveguide and the microstrip line circuit are only suitable for the microwave frequency band. In the millimeter wave frequency band, the rectangular waveguide has complex manufacturing problems, and the microstrip line circuit has the problem of high loss. Therefore, it is necessary to find a new transmission circuit. Design for mmWave frequency band. [0003] In order to seek better development in the high-frequency field, planar waveguides emerged as the times require, and the concept of substrat...
