Abstract

The invention relates to a coupler based on a substrate-integrated gap waveguide. The coupler structure is formed by tightly connecting an upper dielectric plate (5) and a lower dielectric plate (6). The upper surface of the upper dielectric board (5) is printed with a grounded metal layer, and the lower surface is printed with coupled microstrip lines (13); the upper surface of the lower dielectric board (6) is printed with periodic circular metal patches (9), ( 15) and H-type coupled microstrip line (12), the lower surface is printed with a metal layer, and periodic metal via holes (10), (11), (14) are punched on the lower dielectric board (6). The invention has the advantages of easy integration, small size, wide bandwidth, low loss, high isolation and the like.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a coupler based on a substrate-integrated gap waveguide. Background technique [0002] The directional coupler is an important microwave and millimeter wave device. The directional coupler is a general microwave / millimeter wave component that can be used for signal isolation, separation and mixing, such as power monitoring, source output power stabilization, signal source Sweep frequency test of isolation, transmission and reflection, etc. The forms of couplers mainly include waveguide couplers and microstrip couplers. With the development of communication systems, the frequency requirements for microwave and millimeter wave devices are getting higher and higher. However, traditional rectangular waveguide couplers and microstrip couplers have large losses at high frequencies, which limits their application at high frequencies. [0003] The emergence of Substrate Integrated ...
