Title (EN) MULTI-MODE COMPOSITE ANTENNA
(FR) ANTENNE COMPOSITE MULTIMODE
Abstract:
(EN) A multi-mode composite antenna includes two crossed dipole elements each consisting of a bow- tie antenna having two bow-tie antenna segments, and a conductive tube which houses signal transmission lines connected to each bow-tie antenna segment. A conductive flared portion surrounds the conductive tube and forms a monopole element. The bow-tie antenna segments are shaped so that slots extend between each adjacent bow-tie antenna, each slot forming a tapered slot antenna that has a pair of non-linear curved edges that diverge from each other.
(FR) L'invention porte sur une antenne composite multimode qui comprend deux éléments dipolaires croisés, constitués chacun d'une antenne en nœud papillon comprenant deux segments d'antenne en nœud papillon, et un tube conducteur qui loge des lignes de transmission de signal connectées à chaque segment d'antenne en nœud papillon. Une partie évasée conductrice entoure le tube conducteur et forme un élément monopolaire. Les segments d'antenne en nœud papillon sont façonnés de manière que des fentes s'étendent entre chacun des segments d'antenne en nœud papillon adjacents, chaque fente formant une antenne à fente effilée qui présente une paire de bords incurvés non linéaires qui divergent l'un de l'autre.
