Title (EN) DIVERSITY ANTENNA FOR MOBILE TERMINAL AND MOBILE TERMINAL THEREOF
(FR) ANTENNE DE DIVERSITÉ POUR TERMINAL MOBILE ET TERMINAL MOBILE CORRESPONDANT
(ZH) 一种移动终端的分集天线及移动终端
Abstract:
(EN) A diversity antenna for a mobile terminal and the mobile terminal are provided, wherein the diversity antenna comprises a printed circuit board (PCB), and a main antenna, a sub-antenna, a first feed port, a second feed port and a matching circuit which are arranged on the PCB. The main antenna is connected to the first feed port through the matching circuit. The sub-antenna is connected to the second feed port through the matching circuit. At least one aperture is disposed between the first feed port and the second feed port. By means of changing the shape of the PCB between the feed ports of the main antenna and the sub-antenna, that is, disposing apertures between the two feed ports which are connected to the main antenna and the sub-antenna respectively, the present invention increases the current path and current loss on the PCB, thereby increases isolation between the two feed ports. The diversity antenna of the present invention enables diversity performance in a smaller space, and also enables a simple structure, a small volume and a low cost.
(FR) L'invention porte sur une antenne de diversité pour terminal mobile et sur le terminal mobile, l'antenne de diversité comprenant une carte de circuit imprimé (PCB), et une antenne principale, une antenne secondaire, un premier port d'alimentation, un second port d'alimentation et un circuit d'adaptation qui sont agencés sur la PCB. L'antenne principale est connectée au premier port d'alimentation par l'intermédiaire du circuit d'adaptation. L'antenne secondaire est connectée au second port d'alimentation par l'intermédiaire du circuit d'adaptation. Au moins une ouverture est agencée entre le premier port d'alimentation et le second port d'alimentation. Par changement de la forme de la PCB entre les ports d'alimentation de l'antenne principale et de l'antenne secondaire, à savoir par agencement d'ouvertures entre les deux ports d'alimentation qui sont connectés à l'antenne principale et à l'antenne secondaire respectivement, la présente invention augmente le chemin de courant et les pertes de courant sur la PCB, accroissant de ce fait l'isolation entre les deux ports d'alimentation. L'antenne de diversité de la présente invention permet un fonctionnement en diversité dans un plus petit espace, et permet également une structure simple, un petit volume et un bas coût.
