Abstract: front page image
(EN)It is possible to provide an ultra-wide band and high performance antenna at a low cost. An antenna element constituting a part of an opening cross section structure of a double cylinder ridge waveguide is spread on a plane. The antenna element has a ridge element unit (21) for adjusting antenna characteristic corresponding to a ridge portion and a radial element unit (22) for electromagnetic wave radiation. Substantially at the tip end of the ridge element unit (21), a feed terminal (24) is formed. Ground units (23a, 23b) are maintained at the ground potential and the feed terminal (24) is introduced outside as a coplanar waveguide.
(FR)La présente invention concerne une antenne économique à bande ultra large et à hautes performances. Un élément d’antenne constituant une partie d’une structure de section transversale ouverte d’un double guide d’ondes à nervure cylindrique est étalé sur un plan. L’élément d’antenne comprend une nervure (21) pour ajuster les caractéristiques de l’antenne correspondant à une partie de nervure et un élément radial (22) pour le rayonnement des ondes électromagnétiques. Une borne d’alimentation (24) est formée sensiblement à l’extrémité de l’élément nervure (21). Le potentiel de terre est conservé sur les unités de terre (23a, 23b) et la borne d’alimentation (24) est introduite à l’extérieur en tant que guide d’ondes coplanaire.
