Provided is a short-slot type waveguide coupler which can be applied to a transmission line that transmits broadband signals. The waveguide coupler according to the present invention is a short-slot type waveguide couplers wherein it includes a plurality of waveguide units which have a separate port for inputting or outputting signals respectively and a joint unit which combines a plurality of waveguide units and have a specific length in a predetermined direction. Here, at least one waveguide unit extends to a direction that forms a predetermined angle from a longitudinal direction of the joint unit.
