Abstract

Abstract Translated from French Coupleur directionnel hyperfréquence à quatre lignes de transmission comprenant, pour la liaison des lignes de transmission (10a, 10c) et (20a, 20c), quatre tronçons de ligne (10b) et (20b) perpendiculaires, de largeur inférieure à celle des lignes de transmission et reliés électriquement dans leur zone centrale (40), et, superposé de façon symétrique à ces deux tronçons de ligne pour réaliser avec eux un couplage capacitif ou galvanique en quatre zones (11a, 21a, 11b, 21b), un anneau résonnant (30) de largeur sensiblement égale à celle des lignes de transmission et de périmètre moyen tel que la fréquence de résonance soit située juste au-dessous de la bande passante du coupleur. Application: coupleurs et circuits répartiteurs de puissance passifs. Directional microwave coupler with four transmission lines comprising, for the connection of the transmission lines (10a, 10c) and (20a, 20c), four sections of line (10b) and (20b) perpendicular, of width less than that of the lines of transmission and electrically connected in their central zone (40), and, superimposed symmetrically on these two line sections to achieve with them a capacitive or galvanic coupling in four zones (11a, 21a, 11b, 21b), a resonant ring ( 30) of width substantially equal to that of the transmission lines and of average perimeter such that the resonance frequency is located just below the passband of the coupler. Application: couplers and passive power distributor circuits.
