Abstract

Les modes de réalisation de la présente invention ont trait au domaine des communications et concernent une antenne et un terminal, laquelle antenne comprend : une première antenne, une unité de mise à la terre, un fil de terre et une seconde antenne. L'unité de mise à la terre est placée entre la première et la seconde antenne, mais n'est en contact avec aucune de ces antennes. Une extrémité de l'unité de mise à la terre est connectée au fil de terre. L'unité de mise à la terre présente une structure symétrique et son axe de symétrie est perpendiculaire au fil de terre. La première et la seconde antenne sont respectivement connectées au fil de terre par des ports d'alimentation électrique correspondants. La présente invention met en oeuvre deux antennes dans un espace réduit et utilise une unité de mise à la terre symétrique entre ces deux antennes. L'isolation de chaque antenne l'une par rapport à l'autre permet d'offrir une excellente complémentarité des deux diagrammes d'antenne, d'améliorer le degré d'isolation et le coefficient de corrélation des deux antennes et de réduire la difficulté d'un développement d'antenne.
