Problems solved by technology

[0004] 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

The invention discloses a 5G waveguide coupler with a water-proof function. The 5G waveguide coupler comprises a main waveguide and a sub-waveguide which are provided with ports used for inputting oroutputting signals, wherein a combination part with special length in a predetermined direction is formed between the main waveguide and the sub-waveguide; coupling windows are formed in the combination part; an E-plane gap is formed between the coupling windows; the main waveguide comprises a through end; the sub-waveguide comprises a coupling end; the through end comprises an input port P1 and athrough port P3; and the coupling end comprises an isolation port P2 and a coupling port P4. The 5G waveguide coupler has the benefits that the combination part, the coupling windows and the E-planegap are formed in the main waveguide and the sub-waveguide, so that the defect of oversize length of the coupler caused by distribution of all coupling holes in one length direction is avoided; and the 5G waveguide coupler is good in coupling, high in isolation degree, simple in structure and easy to process, and can be conveniently integrated in a high-band circuit.
