Abstract

The invention provides an antenna device and a mobile terminal. The antenna device comprises an antenna, a front end module, a first power amplifier, a first filter and an anti-interference module; the antenna is connected with the front end module, the front-end module and the first power amplifier are connected to form a first access, the front-end module, the first filter and the first power amplifier are connected in sequence to form a second access, and the anti-interference module is connected with the first power amplifier; and the anti-interference module is used for acquiring a working frequency band of a carrier in real time, controlling the first power amplifier to close the first access and open the second access when the working frequency band of the carrier satisfies a preset condition, and controlling the first power amplifier to open the first access and close the second access when the working frequency band of the carrier does not satisfy the preset condition. The antenna device provided by the invention has the beneficial effects of reducing the harmonic interference during carrier aggregation.

Description

technical field [0001] The present invention relates to the communication field, in particular to an antenna device and a mobile terminal. Background technique [0002] The whole people has entered the 4G era. Currently, operators require 4G+, which is technically called Carrier Aggregation (Carrier Aggregation) technology. [0003] Carrier aggregation of two frequency bands requires high isolation between the two frequency bands. When one frequency band is working, it cannot affect the other frequency band. If the isolation is not enough, the reception of the other frequency band will be affected. For example, when carrier aggregation is performed between the B8 frequency band and the B7 frequency band, or when the carrier aggregation is performed between the B8 frequency band and the B3 frequency band. The B8 frequency band is used as the main carrier component PCC of the main cell, and B3 or B7 is used as the secondary carrier component of the secondary cell. The second ...
