Samenvatting

The present invention relates to a transition arrangement (100) comprising a transition between a substrate integrated waveguide, SIW, (20) of a circuit arrangement and a waveguide and/or antenna structure (10). It comprises a first conducting plate (1) and a second conducting plate (2). The SIW (20) is arranged on said first conducting plate, and an impedance matching structure (4) is connected to the second conducting plate. For a transition between the SIW (20) and the waveguide structure, the impedance matching structure (4) is extended with an open circuit λg/4 stub (5) for inverting the impedance to effectively provide a short-circuit connection, thereby electromagnetically coupling the EM-field between the SIW and the impedance matching structure (4), which is so arranged that, when the first and second conducting plates are interconnected,or merely assembled in a contactless manner in the case of gap structures, the open circuit λg/4 stub (5) is disposed above the SIW without any galvanic contact between the SIW and the impedance matching structure (4) and between the SIW (20) and the λg/4 stub (5), providing a planar, contactless transition
