Abstract
L'ANTENNE PLANE SELON LA PRESENTE INVENTION COMPREND UN EMPILEMENT D'UN CIRCUIT RAYONNANT 16, DE PREMIERE ET SECONDE ENTAILLES 18, 19 D'ALIMENTATION EN COURANT ET D'UN CONDUCTEUR 24 DE TERRE QUI SONT DISPOSES DE FACON INDEPENDANTE LES UNS DES AUTRES, DES COUCHES DIELECTRIQUES ETANT INTERPOSEES ENTRE DES ELEMENTS 16B FORMANT DES PARCELLES DU CIRCUIT RAYONNANT, CES ELEMENTS, DISPOSES RESPECTIVEMENT DANS DES ENTAILLES 16 PRATIQUEES DANS LE CIRCUIT, SONT COUPLES ELECTROMAGNETIQUEMENT A DES BORNES D'ALIMENTATION EN COURANT DES DEUX CIRCUITS D'ALIMENTATION EN COURANT AU LIEU DE LEUR ETRE CONNECTES DIRECTEMENT. LE CIRCUIT RAYONNANT ET LES BANDES D'ALIMENTATION EN COURANT N'ONT AINSI PAS A ETRE RELIES DIRECTEMENT ENTRE EUX ET IL N'EST PAS NECESSAIRE D'ADAPTER LEURS IMPEDANCES RECIPROQUES, CE QUI FAIT QUE LES POSSIBILITES D'ASSEMBLAGE SE TROUVENT AMELIOREES DANS UNE GRANDE MESURE.
