Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] An antenna device can be used in the wireless communication process of a mobile terminal. The antenna device includes an antenna ground, a first feed port, a first antenna, a first adjustment unit, a first switch unit, a second switch unit and a control unit. Specifically, the antenna ground may be a main board or other metal ground of the mobile terminal where the antenna device is located. The first feeding port is used for connecting with the radio frequency unit, so as to perform signal transmission with the radio frequency unit. The first antenna is respectively connected to the first...

Abstract

The invention relates to an antenna device which comprises an antenna ground and also comprises a first feed port, a first antenna, a first regulation unit, a first switch unit, a second switch unit and a control unit, wherein the first feed port is used for connection with a radio frequency unit and signal transmission with the radio frequency unit; the first antenna is connected with the first feed port and the antenna ground respectively; one end of the first regulation unit is connected between the first feed port and the first antenna, and the other end is connected with the first switch unit; the first regulation unit is used for regulating the working frequency band of the first antenna; the other end of the first switch unit is connected with the antenna ground; one end of the second switch unit is connected with an antenna structure, far away from the antenna ground, on the first antenna, and the other end is connected with the antenna ground; and the control unit is used for respectively controlling the closing and opening of the first switch unit and the second switch so as to control the working condition of the first antenna. The antenna device has the characteristic of small space size, and meanwhile, multi-frequency band is achieved. The invention also relates to a mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a mobile terminal and an antenna device. Background technique [0002] In order to meet the miniaturization development requirements of the mobile terminal, the spatial size of the antenna device should also be miniaturized. However, with the increase of wireless communication providers, different wireless communication providers often use different signal transmission frequency bands. In order to ensure the normal wireless communication of the mobile terminal under different wireless network environments, the antenna device needs to be able to realize multi-band operation. Traditional antenna devices often implement multiple frequency bands by adding multiple parasitic resonances. This method will increase the space size of the antenna device, which is not conducive to use in mobile terminals that are increasingly miniaturized. Contents of the invention...
