Abstract

The invention discloses an antenna module, which comprises a main radiator and a systematic unit, wherein the systematic unit is opposite to the main radiator and is separated from the main radiator at a preset distance; the main radiator comprises a first fracture and a second fracture; the first fracture and the second fracture partition the main radiator into a first radiator, a second radiator and a third radiator; the second radiator and the third radiator are located at two sides of the first radiator respectively; the antenna module comprises a first grounding circuit, a second grounding circuit and a feeding circuit, which are electrically connected between the systematic unit and the first radiator; the feeding circuit is located between the first grounding circuit and the second grounding circuit; the antenna module comprises control switches which are electrically connected to the first grounding circuit and the second grounding circuit; the control switches are used for controlling on/off of the grounding circuits; the antenna module also comprises an adjustable matching circuit; and one end of the adjustable matching circuit is electrically connected with the first radiator and the other end is electrically connected with the systematic unit.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an antenna module used in mobile electronic communication products. Background technique [0002] With the development of wireless communication technology, mobile terminal devices such as mobile phones, tablet computers, and portable multimedia players are widely used in people's lives. The mobile terminal device is usually equipped with an antenna module to transmit and receive wireless signals, so as to support the wireless communication function of the mobile terminal device. [0003] In order to improve and enhance the overall firmness of the product, more and more mobile terminal devices such as smartphones currently use metal casings, such as metal back covers or metal frames, and metal casings can shield or absorb electromagnetic waves to a certain extent. The problem of narrow frequency band and low efficiency With the development of mobile communication technology, ...
