Problems solved by technology

[0003] The existing mobile phone antenna is installed on the mobile phone to receive and transmit mobile phone signals. Most of the existing mobile phone antennas are installed inside the mobile phone, that is, the built-in antenna design. The built-in antenna will increase the thickness of the mobile phone and cannot achieve an all-metal shell

Abstract

The invention provides an antenna device for a mobile terminal. The antenna device comprises first radio-frequency receiving and transmitting circuit, a first matching circuit, a second radio-frequency receiving and transmitting circuit, a second matching circuit and a shell, wherein the shell comprises a first conducting region; the first conducting region is provided with a first micro-gap strip and a first gap; the first micro-gap strip comprises a plurality of first micro-gaps; the first micro-gap is intersected with the plurality of first micro-gaps; the first radio-frequency receiving and transmitting circuit is electrically connected with the first conducting region through the first matching circuit; and the second radio-frequency receiving and transmitting circuit is electrically connected with the first conducting region through the second matching circuit. According to the antenna device provided by the invention, the overall appearance effect of the mobile terminal can be ensured; and meanwhile, receiving and transmitting of a high-frequency signal and a low-frequency signal can be achieved. 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] An antenna is a converter that converts the guided wave propagating on the transmission line into an electromagnetic wave propagating in an unbounded medium, usually free space, or vice versa. It is a component used in radio equipment to transmit or receive electromagnetic waves. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. The basic characteristic parameters of the same antenna as transmitting or receiving are the same. [0003] The existing mobile phone antenna is installed on the mobile phone to receive and transmit mobile phone signals. Most of the existing mobile phone antennas are installed inside the mobile phone, that is, the built-in antenna design. The built-in antenna will increase the thickness of the mobile phon...
