A broadband E ‐plane right‐angle transition from a substrate integrated waveguide (SIW) to a rectangular waveguide (RWG) is proposed. A stepped waveguide, a coupling aperture, and two inductive posts are applied to provide a good impedance matching between the SIW and the RWG. A back‐to‐back transition prototype is designed, fabricated, and measured at Ka‐band. Measured results show a good agreement with the simulated one: the insertion loss of a single transition is <0.6 dB and the return loss better than 15 dB is obtained from 32.6 to 38.1 GHz. The broadband transition can be used in front‐end circuits of millimetre‐wave communication, radar, and measurement systems.
