Microwave adjustment device for a transition between a hollow waveguide and a plane transmission line

摘要

A microwave adjustment device for a transition between a hollow waveguide (11) and a plane transmission line (10), the device comprising: an intermediate coaxial waveguide (12) comprising a core (20) whose first end opens out into the hollow waveguide and terminates in an antenna (23) and whose second end passes through the substrate on which the plane transmission line is deposited; a curved metal tape (26) having a first end fixed to the second end of the core (20); and a screw (27) fixed to the second end of a tape (26) in order to adjust the gap between the second end and the transmission line (18). The invention is applicable to microwave beam telecommunications.
