Abstract

La présente invention concerne une antenne en boîtier et un dispositif terminal. L'antenne en boîtier comprend une antenne à polarisation horizontale et une antenne à polarisation verticale. Une première partie d'élément rayonnant et une deuxième partie d'élément rayonnant de l'antenne à polarisation verticale sont connectées au moyen d'une plaque de masse. Un premier trajet d'alimentation est utilisé pour alimenter la première partie d'élément rayonnant et la deuxième partie d'élément rayonnant. L'antenne à polarisation horizontale comprend un second trajet d'alimentation et une troisième partie d'élément rayonnant disposés dans un substrat. Le second trajet d'alimentation est utilisé pour alimenter la troisième partie d'élément rayonnant. La première partie d'élément rayonnant sert également de masse pour l'antenne à polarisation horizontale. Dans l'antenne en boîtier mentionnée ci-dessus, la première partie d'élément rayonnant de l'antenne à polarisation verticale est directement connectée à la plaque de masse, et par conséquent, la première partie d'élément rayonnant peut servir non seulement de partie de rayonnement de l'antenne à polarisation verticale mais également de masse ; en utilisant la première partie d'élément rayonnant comme masse pour l'antenne à polarisation verticale lors de la configuration de l'antenne à polarisation verticale, il n'est pas nécessaire d'utiliser une masse supplémentaire. Par conséquent, la structure de l'ensemble de l'antenne en boîtier peut être simplifiée.
