Abstract

The present invention provides an antenna device. The antenna device includes a metal frame, and the metal frame includes a first end portion and a second end portion oppositely arranged; one end of the first end portion is extended to form a low-frequency radiation portion, and the other end is extended to form a A high-frequency radiation part arranged opposite to the low-frequency radiation part; the low-frequency radiation part is used to connect to a low-frequency circuit to send and receive low-frequency signals, and the high-frequency radiation part is used to connect to a high-frequency circuit to send and receive high-frequency signals; The metal frame is the frame of a mobile terminal. The invention also provides a mobile terminal.

Description

technical field [0001] The invention relates to an antenna device and a mobile terminal with the antenna device. Background technique [0002] With the development of mobile terminals, more and more metal casings are used in mobile terminals. However, the metal casing will have a certain impact on the radiation performance of the antenna of the mobile terminal. In order to ensure the performance of the antenna, it is often necessary to design the antenna with a larger headroom. As mobile terminals tend to be thinner and lighter, this will undoubtedly increase the difficulty of antenna design. Contents of the invention [0003] The object of the present invention is to provide an antenna device that can effectively reduce the volume of a mobile terminal. The present invention also provides a mobile terminal with the antenna device. [0004] An antenna device, the antenna device includes a metal frame, the metal frame includes a first end and a second end opposite to each...
