Disclosed is a transition apparatus for transitioning wide frequency band electromagnetic waves between the metal waveguide and the laminated waveguide. The transition apparatus includes a top conductive layer, a bottom conductive layer, a conductive wall, and a transition interior. The conductive wall is formed along a substrate of the laminated waveguide and electrically connected the top conductive layer and the bottom conductive layer. The transition interior is defined by the top conductive layer, the bottom conductive layer, and the conductive wall. The conductive wall further comprises a plurality of stubs extending from an inner side of the wall into the transition interior, the plurality of stubs divide the transition interior into three or more resonator cavities for transitioning wide frequency band electromagnetic waves between the metal waveguide and the laminated waveguide.
