Device for transition between wave guide and connector e.g. microstrip line in field of antenna, has impedance matching step enabling radioelectric performances of device to depend on machining precision and positioning precision
The device has an open guide (1a) forming a wave guide (1) nearer to a cover (1b). The wave guide comprises an opening on which an insulating glass bead (2) comprising a conducting core (3) is placed. An impedance matching step (5) is provided to reduce height (H1) of the wave guide, where the wave guide is connected to a coaxial connector (4). The step generates a principal mode in the wave guide so that radioelectric performances of the device between the waveguide and a connector e.g. microstrip line, depend on machining precision and positioning precision.
