A microwave microstrip/waveguide transition structure includes a substrate, an elongated microstrip layer residing on a surface of the substrate, and an elongated integral hollow waveguide on the surface of the substrate. The microstrip layer and a side of the hollow waveguide constitute a single continuous piece of metal. The transition structure is fabricated by providing a substrate, depositing a metallic layer on the substrate, and depositing a metallic hollow housing continuous with a portion of a length of the metallic layer. The metallic hollow waveguide bounded by the metallic layer and the metallic hollow housing and having a contained volume therewithin is thereby defined.
