Abstract

The embodiment of the invention discloses an antenna and a mobile terminal. The antenna comprises a metal routing unit and a closed-loop breakpoint-free metal middle frame. The metal routing unit arranged inside a mobile terminal is connected with the closed-loop breakpoint-free metal middle frame of the mobile terminal and is in electrical conduction and the metal routing unit that is also connected with a circuit board arranged inside the mobile terminal electrically by a feeding point is used for adjusting a resonant frequency of an antenna; and the circuit board is arranged between a structural support metal plate arranged inside the mobile terminal and a metal back cover of the mobile terminal and the structural support metal plate and the metal back cover are connected and are in electrical conduction, and the structural support metal plate and the metal back cover serve as reference grounds of the mobile terminal. The closed-loop breakpoint-free metal middle is used as an irradiator of the antenna and is used for transmitting and receiving a signal. Therefore, on the premise that the closed-loop breakpoint-free metal middle frame and the metal back cover are used by the mobile terminal, the radiation performance of the antenna can be ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an antenna and a mobile terminal. Background technique [0002] With the continuous improvement of users' requirements on the appearance of mobile terminals, the design of mobile phones with metal casings is very attractive to users with its special feel, texture and metallic color. Therefore, more and more mobile terminals with metal appearance appear on the market. [0003] However, in order to avoid the isolation of mobile phone signals by closed conductors, the metal middle frames of most mobile terminals have plastic isolation points, and only a very small number of metal middle frames of mobile terminals are closed loops without breakpoints. The existing mobile terminals that have been published in the middle frame without breakpoints often use loop or slot antennas, and do not support metal back covers, such as application number 201310472716.7 (wireless electronic...
