CA 2218693

Self-tuning materials which can efficiently emit or receive radio waves in spite of being simple in their construction and small in their dimension, and are applied to patch antenna, wave directors or the like. Metallic chips containing two or more kinds of ingredients which are distributed in a layered, net-like or needle-shaped configuration, and an organic or inorganic bonding material which is small in dissipation of electric power under radio waves of high frequencies are mixed with each other, and are pressurized under a high pressure while being highly electrified in the direction perpendicular to the pressurizing direction to mold the metallic chips and the bonding material in a plate-shaped configuration while being heated.

L'invention concerne un matériau à auto-syntonisation utilisable pour une antenne à plaque, un guide d'ondes, etc., et efficace pour le rayonnement des ondes radioélectriques malgré sa structure simple et sa petite taille. On fabrique ce matériau en mélangeant des plaquettes métalliques constituées de deux types de métaux ou plus et répartis en couches, réseaux ou structure d'aiguilles au moyen d'un liant organique ou minéral qui n'occasionne pas de grandes pertes d'énergie aux fréquences élevées, puis en donnant au matériau la forme d'une plaque tandis qu'un courant important le traverse dans une direction perpendiculaire au sens de l'opération de pressage et que l'on effectue cette opération en exerçant une forte pression.
