Abstract

The invention relates to the field of communication and discloses a coupling feed-in type antenna device of a mobile terminal. The coupling feed-in type antenna device of the mobile terminal comprises a metal shell. A first metal arm and a second metal arm stretch out of the lateral surface of the metal shell, wherein the first metal arm and the second metal arm form a fixed space in a enclosing mode, and a notch is formed in the arm end of the first metal arm and the arm end of the second metal arm. An antenna carrier is arranged inside the fixed space. The antenna is provided with an antenna. The antenna comprises a first antenna branch and a second antenna branch. A main board and an antenna connector are arranged inside the metal shell. The first antenna branch and the second antenna branch are respectively connected with the main board through the antenna connector. Due to the fact that the coupling feed-in type antenna device of the mobile terminal is adopted, the problem that communication quality is decreased when a user grips the mobile terminal is solved, and stronger metal texture is provided for the user.

Description

technical field [0001] The invention relates to the communication field, in particular to a coupling-feed antenna device for a mobile terminal. Background technique [0002] In the development process of existing mobile terminals, the products are all developing in the direction of thinner and stronger metal texture, and the thinner and stronger metal texture handheld terminal equipment undoubtedly brings a huge challenge to the design of the antenna. The existing technology adopts a coupled-feed antenna device to solve this challenge. The antenna device adopts a metal ornament to install on the front surface of the mobile phone casing. The first antenna branch is electrically connected to the metal ornament, and the second antenna branch is connected to the first antenna branch. Coupling, the motherboard is connected to antenna branch 1 and antenna branch 2 through the antenna connector to form a "return" antenna loop to solve the problem of communication performance degrad...
