Summary:The invention relates to a device for transition between a waveguide with dual step and an end coaxial line. The transition device according to the invention comprises a waveguide 15a-16a into which is inserted a substrate 12 carrying on each face a conductive strip forming, on the coaxial side 19, a "microstrip" line 13a-14a, and on the waveguide side 20 a bifilar line 13b-14b which is pinched between the two steps 17 and 18 of an adaptation section 15b-16b. The subject of the present invention is mainly applicable to microwave connection circuits. L'INVENTION CONCERNE UN DISPOSITIF DE TRANSITION ENTRE UN GUIDE D'ONDES A DOUBLE REDAN ET UNE LIGNE COAXIALE EN BOUT.LE DISPOSITIF DE TRANSITION SELON L'INVENTION COMPREND UN GUIDE D'ONDE 15A-16A DANS LEQUEL EST INSERE UN SUBSTRAT 12 PORTANT SUR CHAQUE FACE UN RUBAN CONDUCTEUR FORMANT, DU COTE COAXIAL 19, UNE LIGNE "MICROSTRIP" 13A-14A ET DU COTE GUIDE D'ONDES 20 UNE LIGNE BIFILAIRE 13B-14B QUI EST PINCEE ENTRE LES DEUX REDANS 17 ET 18 D'UN TRONCON D'ADAPTATION 15B-16B.L'OBJET DE LA PRESENTE INVENTION EST PRINCIPALEMENT APPLICABLE AUX CIRCUITS HYPERFREQUENCE DE CONNEXION.
