Abstract

The invention provides an antenna device and a mobile terminal. The antenna device comprises a first antenna, a second antenna, a front end module, a transceiver and a first filtering module, wherein the transceiver is provided with a first receiving port and a first transmitting port, and the first filtering module is used for filtering signals beyond a first preset frequency band; and the first receiving port, the first filtering module and the first antenna are connected in sequence to form a receiving channel of auxiliary carrier components of the first preset frequency band, and the first transmitting port, the front end module and the second antenna are connected in sequence to form a transmitting channel of the auxiliary carrier components of the first preset frequency band. The antenna device provided by the invention has the beneficial effects of reducing harmonic interference.

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. At present, operators all require 4G+, which is technically called Carrier Aggregation (CarrierAggregation) technology. [0003] Carrier aggregation of two channels 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, it will affect the reception of the other frequency band. 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 harmo...
