Problems solved by technology

At present, the main directional couplers include microstrip and waveguide directional couplers. However, microstrip lines are not suitable for working in the millimeter wave band due to their large transmission loss. Although non-planar waveguide structures such as dielectric waveguides and rectangular waveguides have small losses and high performance, they are Due to its large size and difficulty in integrated processing, it is difficult to be widely used in highly integrated systems

Abstract

Integrated waveguide directional coupler, involving microwave / millimeter wave technology. The present invention comprises two parallel stacked first substrate integrated waveguides and second substrate integrated waveguides, the lower wide wall of the first substrate integrated waveguide located above and the upper width wall of the second substrate integrated waveguide located below The walls are provided with two rows of circular coupling holes, and the coupling holes on the two waveguides are completely overlapped; the center of the first row of coupling holes on the lower wide wall of the first substrate integrated waveguide is arranged in a straight line, and the center of the second row of coupling holes is in a straight line. Arrangement, the arrangement lines of the centers of the two rows of coupling holes are parallel, and the first row of coupling holes and the second row of coupling holes are symmetrical along the center line of the wide wall in the transmission direction. The invention has wider working bandwidth and smaller insertion loss.

Description

technical field [0001] The present invention relates to microwave / millimeter wave technology. Background technique [0002] A directional coupler is a directional power coupling device that can use the coupled power for detection or power regulation. Directional couplers are widely used in various fields of microwave technology and are one of the most basic microwave components. The basic indicators describing the directional coupler include coupling degree, isolation degree, directivity, working bandwidth and so on. At present, the main directional couplers include microstrip and waveguide directional couplers. However, microstrip lines are not suitable for working in the millimeter wave band due to their large transmission loss. Although non-planar waveguide structures such as dielectric waveguides and rectangular waveguides have small losses and high performance, they are Due to its large size and difficulty in integrated processing, it is difficult to be widely used in...
