Abstract

The invention discloses an antenna device which comprises a radio frequency transmitting and receiving circuit, a matching circuit and a radiating body. The matching circuit is electrically connected between the radio frequency transmitting and receiving circuit and the radiating body. The radiating body is a metal shell of a mobile terminal. The metal shell comprises a first radiating portion, a second radiating portion, a first insulation belt and a first connecting section. The first insulation belt and the first connecting section are located between the first radiating portion and the second radiating portion. The first connecting section is electrically connected between the first radiating portion and the second radiating portion. The first connecting section is electrically connected with the matching circuit. The invention further discloses the mobile terminal. The radiating body of the antenna device is the metal shell of the mobile terminal, so that the radiating efficiency of the antenna device is improved.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an antenna device and a mobile terminal using the antenna device. Background technique [0002] With the development of science and technology and the higher and higher signal requirements of users for electronic products, many mobile terminals with antennas such as mobile phones on the market currently use metal shells to ensure the strength of use while satisfying the texture and improving the user experience. feel. As we all know, metal is a signal shielding material. In order to avoid the signal shielding of the metal casing from affecting the antenna efficiency, the casing is usually designed to combine metal and non-metal, so that the antenna structure is located in the non-metal area. The non-metal area is usually set at both ends of the mobile terminal. Located outside the shielded display area, a circuit board is installed inside the non-metal area, and electro...
