Abstract
(EN)
The present disclosure relates to the technical field of wireless communication, and discloses an index improvement method, antenna array, and base station antenna, said method comprising: crisscrossing and/or nesting a low-frequency radiating element and a high-frequency radiating element on a reflective panel; at least one high-frequency radiating element is insulated from and connected to the reflective panel, and an opening is provided at the connection between the reflective panel and the high-frequency radiating element; the front-to-back ratio of the low-frequency radiating element, the horizontal wave width of the low-frequency radiating element, the horizontal wave width of the high-frequency radiating element, and the third-order passive reflection intermodulation index are improved. In the index improvement method, antenna array, and base station antenna provided by the present disclosure, when the low-frequency radiating element and the high-frequency radiating element are crisscrossed and/or nested, the high-frequency radiating element is insulated from and connected to the reflective panel; without changing the overall dimensions of the entire device, the mutual influence of high and low frequencies is reduced, improving the antenna index.

La présente invention concerne le domaine technique de la communication sans fil, et concerne un procédé d'amélioration d'indice, un réseau d'antennes et une antenne de station de base, ledit procédé comprenant : l'entrecroisement et/ou l'emboîtement d'un élément rayonnant basse fréquence et d'un élément rayonnant haute fréquence sur un panneau réfléchissant ; au moins un élément rayonnant haute fréquence est isolé du et connecté au panneau réfléchissant, et une ouverture est fournie au niveau de la connexion entre le panneau réfléchissant et l'élément rayonnant haute fréquence ; le rapport avant-arrière de l'élément rayonnant basse fréquence, la largeur d'onde horizontale de l'élément rayonnant basse fréquence, la largeur d'onde horizontale de l'élément rayonnant haute fréquence et l'indice d'intermodulation passive de troisième ordre sont améliorés. Dans le procédé d'amélioration d'indice, un réseau d'antennes, et une antenne de station de base fournis par la présente invention, lorsque l'élément rayonnant basse fréquence et l'élément rayonnant haute fréquence sont entrecroisés et/ou emboîtés, l'élément rayonnant haute fréquence est isolé du et connecté au panneau réfléchissant ; sans changer les dimensions globales de l'ensemble du dispositif, l'influence mutuelle de fréquences élevées et basses est réduite, améliorant l'indice d'antenne.
