Abstract

The embodiment of the invention provides an antenna device and a mobile terminal. The antenna device comprises a front shell, and a main board, an antenna small board, an antenna radiator, a feed point elastic sheet and a grounding elastic sheet which are arranged in the front shell, wherein the feed point elastic sheet is arranged on the antenna small board and is used for connecting the feed line on the antenna small board with the antenna radiator, the grounding elastic sheet is arranged on the front shell, the first end of the grounding elastic sheet is connected to the grounding point onthe front shell, the second end of the grounding elastic sheet is connected to the antenna radiator, and the grounding point on the front shell is connected to the ground wire of the main board. According to the embodiment of the invention, the antenna grounding connection mode is improved, so that the antenna grounding yield is improved, the current return path is shortened, and the antenna performance and the overall performance of the mobile terminal are improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an antenna device and a mobile terminal. Background technique [0002] At present, the antenna radiator is first connected to the antenna plate through the shrapnel, and then the antenna plate is grounded to the ground point on the front shell of the mobile phone, and then connected to the GND of the main board through the ground point. The circuit return path is very long, and the antenna is small. The board is grounded through conductive foam or conductive cloth, and there are often poor contact problems. Frequent reliability problems occur during mass production, resulting in production stoppages and delays in shipments. Contents of the invention [0003] Embodiments of the present application provide an antenna device and a mobile terminal. By improving the connection mode of the antenna ground, the yield rate of the antenna ground is improved, the curr...
