A novel air‐filled E ‐plane rectangular waveguide (RWG) to substrate integrated waveguide (SIW) transition, which is suitable for Ka‐band large‐scale antenna arrays, is presented. The power is coupled between the RWG and SIW through two slots: one etched on the SIW ground plane and the other cut through metallic RWG narrow side wall ( E ‐plane). A back‐to‐back transition is designed, fabricated, assembled, and tested. Measured results show a good agreement with the simulated ones. An SIW attenuation loss ≤0.33 dB/1 cm and a transition return loss better than 10 dB have been experimentally obtained over the band 28.30–30.8 GHz.
