The invention relates to a process for reducing the dimensions and dramatically reducing the manufacturing cost, and of increasing the reliability of microwave components such as antennae (2), poer dividers, filters, directional couplers and oher types of integrated line networks, by producing a surface layer with a high dielectric constant on an aluminium substrate by hard anodization in combination with flat conductor technology. L'invention concerne un procédé permettant de réduire les dimensions et plus encore le coût de fabrication, tout en améliorant la fiabilité, de composants micro-onde, notamment d'antennes (2), de diviseurs de fréquence, de filtres, des coupleurs directionnels et d'autres types de réseaux à lignes intégrées, ce procédé consistant à produire une couche de surface, de constante diélectrique élevée, sur un substrat d'aluminium par anodisation dure en combinaison avec une technologie de conducteur plat.
