The invention discloses a substrate integrated waveguide-to-rectangular waveguide conversion device, which comprises a circuit board, a rectangular waveguide, a coupling patch antenna, a coupling window, a coupling ground hole, shielding ground holes and a matching ground hole, and is characterized in that the substrate integrated waveguide is arranged in a first area of the circuit board, and the plurality of shielding ground holes form a semi-closed second area with an input port; an input port of the second area is in butt joint with an output port of the substrate integrated waveguide, a matching ground hole is formed in the inner side of a via hole of the substrate integrated waveguide, the rectangular waveguide is perpendicular to and tightly connected with the circuit board, a contact area of the rectangular waveguide and the circuit board covers a coupling window arranged in the second area, and the coupling patch antenna is arranged in the coupling window. The coupling ground holes are formed in the
