Abstract
The present invention relates to an element of transition between a waveguide and a transition line on a substrate. The element of transition comprises a securing flange on the substrate, the flange 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.
