Abstract

Provided in the present invention is an antenna device, comprising: a radio frequency transceiver circuit; a match circuit, which is electrically connected to the radio frequency transceiver circuit; and a metal cover, which is provided with at least one band of micro seams. The radio frequency transceiver circuit is electrically connected to the metal cover by means of the match circuit, such that the metal cover is used as a radiating body of the antenna device. The metal cover is grounded by means of a grounding wire, the grounding wire being provided with a switch thereon for connecting / disconnecting the grounding wire. The antenna device according to the present invention can guarantee the overall appearance of a mobile terminal, and meanwhile, can prevent signals of the antenna device from being interfered and improve the bandwidth of the antenna device. Further provided in the present invention is a 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...
