Abstract

Une antenne produisant, en polarisation circulaire, un diagram-me de rayonnement de révolution autour d'un axe (1) et présentant un minimum de rayonnement dans la direction de cet axe, caractérisée en ce qu'elle comprend:
- une surface conductrice réflectrice (2), essentiellement de ré-volution autour de l'axe, - un brin conducteur rectiligne (6), s'étendant axialement de-puis une première extrémité (7), située au niveau de cette sur-face conductrice et isolée de celle-ci, jusqu'à une seconde extré-mité (8), ce brin conducteur étant relié à sa première extré-inité à une ligne d'alimentation (4, 5), et - une pluralité de bras rayonnants (9, 10), comportant chacun une première partie (9) s'étendant essentiellement dans un plan radial (11) depuis la seconde extrémité du brin conduc-teur, cette première partie étant, A son extrémité proximale, électriquement reliée de façon directe au brin conducteur et étant, à son extrémité distale, prolongée par une seconde par-tie (10) en forme de brin curviligne s'inscrivant typiquement sur une sphère centrée à ladite seconde extrémité et dont la direction générale est inclinée par rapport audit plan radial.
