Abstract

The invention provides an antenna device. The antenna device comprises a radio frequency receiving and transmitting circuit, a match circuit electrically connected to the radio frequency receiving and transmitting circuit and a metal shell; the metal shell is provided with at least one micro gap tape, and the radio frequency receiving and transmitting circuit is electrically connected with the metal shell through the match circuit, so that the metal shell is used as a radiating body of the antenna device; the metal shell is grounded through a grounding wire, and the grounding wire is provided with a switch used for controlling on-off of the grounding wire. According to the antenna device, the overall appearance effect of a mobile terminal can be guaranteed, signals of the antenna device can be prevented from being interfered, and the bandwidth of the antenna device can be increased. The invention further 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...
