Abstract

The invention provides an antenna device. The antenna device comprises a radio frequency transceiving circuit, a matching circuit and a metal shell, wherein the matching circuit is electrically connected to the radio frequency transceiving circuit, the edge of the metal shell comprises an arc segment, the metal shell is provided with at least one micro-slot belt, the at least one micro-slot belt comprises an arc part, the arc part is matched with the arc segment of the metal shell, the radio frequency transceiving circuit is electrically connected with the metal shell through the matching circuit so that the metal shell is used as a radiation body of the antenna device, the metal shell is grounded by a grounding line, and a switch is arranged on the grounding line and is used for controlling on / off of the grounding line. With the antenna device according to the invention, the comprehensive appearance effect of a mobile terminal can be ensured, meanwhile, a signal of the antenna device can be prevented from being intervened, and the bandwidth of the antenna device is improved. The invention also provides the mobile terminal.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to an antenna device and a mobile terminal. Background technique [0002] In the market, all-metal housings are becoming more and more popular with consumers, but considering the limitations of the antenna device, a metal and non-metal housing is usually used, and the antenna device is located in a non-metallic area to prevent the signal from the antenna device from being shielded . [0003] The casings of existing mobile terminals mostly adopt a three-section structure, that is, the metal area in the middle of the casing is isolated from the metal areas at both ends of the casing by isolation strips filled with non-signal shielding materials. The antenna assembly is located close to the isolation strip to prevent its signal from being shielded. But the barrier strip will be clearly seen by consumers, thus affecting the overall appearance of the casing of the mobile terminal. C...
