Abstract

L'invention concerne une antenne électromagnétique comportant une première partie rayonnante (12) à guide d'ondes électromagnétiques de forme géométrique prédéterminée, formant un premier milieu de propagation électromagnétique et comportant une première paroi (18) de rayonnement comportant une pluralité de fentes rayonnantes (22) espacées, chaque fente rayonnante (22) s'étendant selon une première direction longitudinale, et une deuxième paroi (20), opposée à la première paroi (18). L'antenne comporte une deuxième partie active (14) comprenant un empilement d'au moins deux couches diélectriques (42, 44), au moins une des couches diélectriques étant gravée d'au moins une piste métallique aboutissant à au moins un circuit actif, formant un deuxième milieu de propagation électromagnétique, au moins une portion de ladite deuxième partie active étant plaquée contre ladite deuxième paroi dans une zone de contact. Une fente de couplage (30, 30a, 30b) est située dans ladite zone de contact, la fente de couplage traversant ladite deuxième paroi (20) et s'étendant selon une deuxième direction formant un angle d'orientation non nul avec ladite première direction longitudinale.
