Abstract

Doublet équilibré muni d'un câble coaxial branché entre la charge, ou source, et les bras de gauche et de droite du doublet afin d'élimine essentiellement le courant du mode commun et la radiosité entre le câble coaxial et les bras du doublet. La connexion entre le câble coaxial de la source/charge et les bras du doublet est un transformateur symétrique muni d'une branche centrale qui constitue un prolongement du câble coaxial de la source/charge, avec des embases de gauche et de droite. Lorsque les embases constituent des segments du câble coaxial, les conducteurs extérieurs des embases de gauche et de droite du transformateur symétrique sont branchés aux bras du doublet correspondants, et l'un des conducteurs intérieurs est branché au conducteur intérieur de la branche centrale, alors que l'autre conducteur intérieur est branché au conducteur extérieur.
