Embodiment Construction

[0039] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] The present invention proposes based on following discovery and research of inventor:

[0041] The improvement scheme in the related technology, the core idea is to change the position of the antenna feed point, thereby improving the performance of the left and right head and hand models. Although changing the position of the antenna feed point can improve the performance of the left and right head and hand models, changing the position of the antenna end can also Improve the performance of the left and right hand models, and the improvement effect is more obvious.

[0042] Further research found that the "death grip" problem is mainly caused when the thumb side of the hand is close to a certain side of the gap in the mobil...

Abstract

The present invention provides a mobile terminal of a mobile terminal and the mobile terminal. The antenna device comprises a first antenna radiator, a feed-in device, an antenna feed, a first switch module, a second switch module and a controller. The first antenna radiator is composed of a first antenna radiator branch and a second antenna radiator branch, wherein the first antenna radiator branch and the second antenna radiator branch are symmetrical. The antenna feed is respectively connected with the feed-in device and the main board of the mobile terminal. The first switch module is respectively connected with the first antenna radiator branch and the main board. The second switch module and the first switch module are symmetrically arranged. The second switch module is respectively connected with the second antenna radiator branch and the main board. The controller is connected with the first switch module and the second switch module, respectively. The controller controls the first switch module to be switched on and the second switch module to be switched off, or controls the first switch module to be switched off and the second switch module to be switched on. According to the technical scheme of the invention, only one antenna feed point and two switches are required to balance the fingerprint function at left and right ends. Therefore, the device is low in cost, small in switching loss and small in end-fingerprint absorption. Moreover, the Grasp of Dead problem can be solved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an antenna device for a mobile terminal and a mobile terminal. Background technique [0002] In recent years, with the popularity of mobile terminals with a metal appearance, the antennas of mobile terminals often need to be realized with metal parts, which significantly increases the impact of the head and hands on the antenna. Adding heads and / or hands will not only make the resonant frequency of the antenna A large offset will lead to serious mismatch, and will also significantly increase the absorption loss of the antenna, and the antenna is very likely to have a "death grip" problem. "Death grip" refers to the situation where the mobile terminal signal rapidly fades after holding the antenna. [0003] At present, major operators and mobile terminal manufacturers attach great importance to the wireless performance of mobile terminals under the head-and-hand ...
