The invention discloses an antenna device of a mobile terminal and the mobile terminal. The antenna device comprises a plurality of antennas, a main board which comprises a plurality of feed sources respectively connected with a plurality of antennas, a metal battery cover which comprises a plurality of first ground points, and a plurality of first connectors which connect a plurality of first ground points and a plurality of second ground points of the main board. The plurality of second ground points are respectively corresponding to the plurality of feed sources. According to the antenna device, a plurality of positions on the metal battery cover are selected as ground points; the ground points are connected through the connectors, so that current excited by the surface of the metal battery cover quickly return to the ground of the main board through the circuit of the connectors and the ground points; and a lot of uncertain factors caused by secondary radiation on the antenna performance can be effectively avoided.
Description
technical field [0001] The present invention relates to the technical field of mobile terminal manufacturing, in particular to an antenna device for a mobile terminal and the mobile terminal. Background technique [0002] With the rapid development of the field of mobile terminal manufacturing technology and the increasing demands of people's lives, more and more users hope that the mobile terminal can have a more dazzling appearance to show their individuality. The mobile terminal with the metal battery cover has gradually been welcomed by more and more users because of its good appearance. However, the conductivity of the metal battery cover will cause secondary radiation, which will bring many uncertainties to the performance of the antenna. The metal battery cover must be treated to effectively reduce the negative impact of the metal battery cover on the antenna. Therefore, how to design or arrange the structural or positional relationship between the metal battery cove...
