Abstract

Abstract Translated from French La partie rayonnante de l'antenne est formée de deux doublets rayonnants (1-3, 2-4) semblables qui sont situés dans un même plan et orthogonaux, les fentes entre les brins alimentés des doublets se croisent au centre (C) de l'antenne élémentaire. Les deux doublets élémentaires (1-3, 2-4) sont associés à des conducteurs centraux de lignes triplaques qui sont orthogonaux, leurs projections se croisant sous le centre (C) de l'antenne. Chaque ligne triplaque est constituée par les plaques (1-3 ou 2-4) d'un doublet, d'une part, un réflecteur, d'autre part, et, entre les plaques et le réflecteur, le conducteur central. Le réflecteur est commun aux deux doublets. The radiating part of the antenna is formed by two similar radiating doublets (1-3, 2-4) which are located in the same plane and orthogonal, the slits between the strands supplied with the doublets cross at the center (C) of l elementary antenna. The two elementary doublets (1-3, 2-4) are associated with central conductors of triplate lines which are orthogonal, their projections crossing under the center (C) of the antenna. Each triplate line is formed by the plates (1-3 or 2-4) of a doublet, on the one hand, a reflector, on the other hand, and, between the plates and the reflector, the central conductor. The reflector is common to the two doublets.
