Abstract

The invention discloses an antenna device and a switching method applied to a handheld mobile terminal, which solves the problem that the handheld effect has a great influence on the antenna signal of the handheld mobile terminal. The antenna device includes: a feed-in antenna and a multi-frequency signal in the mobile terminal Source feed connection; at least two parasitic antennas, located at both ends of the feed antenna, and form a coupling gap with the feed antenna, the feed antenna can be connected to the parasitic antenna through the coupling gap The coupling generates a resonant signal; each of the parasitic antennas is connected to the reference ground through a tuning switch, and the tuning switch is used to control the coupling between the feed-in antenna and the parasitic antenna to generate a resonant signal to be fed into the antenna. The present invention adopts the multi-branch switching design of the antenna, and selects the working parasitic antenna to avoid the position where the human hand absorbs the strongest signal, so that the human hand has the least influence on the performance of the antenna in the left and right hand-held scene.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an antenna device and a switching method applied to a handheld mobile terminal. Background technique [0002] With the development of smart mobile terminal technology, mobile phones have become the main terminal carrying consumer interactive information. Based on the individual needs of consumers and the fierce competition in mobile phone products, all-metal appearance mobile phones and full-screen designs, with their unique feel and appearance, It is widely favored by consumers and has become the trend of mobile phone design. [0003] Due to the strong shielding of the built-in antenna by the all-metal shell, the existing new antenna technology cuts the metal shell and uses a part of the metal shell as the radiator of the antenna to ensure the high radiation frequency of the antenna. At the same time, while the antenna radiation problem is solved, since people wi...
