In this article, the potential of building an air‐filled E ‐plane metallic rectangular waveguide (RWG) with slot transition fabricated by 3D printing technology is explored for millimeter‐wave applications. It is low cost, light weight, and neither plating nor assembly is required compared to the traditional machined metallic RWG. A printed metallic RWG back‐to‐back transition is designed, fabricated, and tested over the frequency band 27–31 GHz. The measured results are compared to those of the machined metallic RWG. Good agreements between the measured results as well as the simulated results are observed.
