Contact-free element of transition between a waveguide and a microstrip line

摘要

The present invention relates to an element of transition between a waveguide 10 and a transition line on a substrate 30. The element of transition comprises a securing flange 20 on the substrate 30, the flange 20 being dimensioned so that at least, in the direction microstrip line, the width d of the flange is selected in such a manner as to shift the resonant modes away from the useful band.;The invention is used particularly for circuits using SMD techniques at millimeter frequencies.
