The invention discloses a conversion structure from a planar transmission line to a rectangular waveguide, which comprises a multilayer floor, a planar transmission line, a matching unit and a rectangular waveguide, the multilayer floor is hollowed out at a position corresponding to the waveguide to form a standard waveguide port area, the matching unit is arranged in the standard waveguide port area, the matching unit is E-shaped, and the rectangular waveguide is arranged in the matching unit. The branch knot comprises a transverse branch knot and three longitudinal branch knots, and the middle longitudinal branch knot corresponds to the strip line. The E-shaped matching unit is simple in structure, two U-shaped parts formed by three longitudinal branches and one transverse branch of the E-shaped structure have capacitance characteristics, the capacitance characteristics are small in change along with frequency, the broadband matching performance is better, compared with a common square matching structure, t
