Abstract

Disclosed in an embodiment of the invention are an antenna and mobile terminal. The antenna comprises: a metal trace configured to adjust a resonant frequency of the antenna, located inside a mobile terminal, connected to and electrically connected to a closed-loop metal center frame of the mobile terminal not having a breakpoint, and electrically connected, via a power feed point, to a circuit board in the mobile terminal, wherein the circuit board is located between a metal structure-supporting plate in the mobile terminal and a metal back cover of the mobile terminal, and the metal structure-supporting plate is connected to and electrically connected to the metal back cover. The metal structure-supporting plate and the metal back cover serve as reference grounds of the mobile terminal. The closed-loop metal center frame not having a breakpoint serves as a radiator of the antenna to emit and receive signals. The invention enables a mobile terminal to use a closed-loop metal center frame not having a breakpoint and a metal back cover, ensuring radiation performance of an antenna.

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...
