Abstract

The invention provides an antenna device, comprising a first radio frequency transceiving circuit, a first matching circuit, a second radio frequency transceiving circuit, a second matching circuit and a metal shell, wherein the metal shell is provided with a micro gap strip and a gap, the micro gap strip comprises a plurality of micro gaps, the gap intersects with the plurality of micro gaps, the micro gap strip is arranged in an edge area adjacent to the short edge of the metal shell, the first radio frequency transceiving circuit is electrically connected with the metal shell via the first matching circuit, and the second radio frequency transceiving circuit is electrically connected with the metal shell via the second matching circuit. The antenna device can ensure the overall appearance effect of a mobile terminal, realizes coverage of the whole frequency band of a main antenna and avoids adverse influence on the radiation performance of the antenna when held by hand. The invention further provides 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] 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...
