Embodiment Construction

[0070] see figure 1 As shown, it is a structural diagram of an embodiment of the antenna device 100 and the mobile terminal 200 of the present invention. In this embodiment, the mobile terminal 200 includes the antenna device 100 . The antenna device 100 includes a first antenna 1001 , a first duplexer 1002 , a control unit 1003 , a first coupling adjustment unit 1004 and a first matching adjustment unit 1005 . The first antenna 1001 is used for receiving and transmitting signals. The first duplexer 1002 is electrically connected to the first antenna 1001 . The first duplexer 1002 includes one low-pass filter and one high-pass filter for separating the signal received by the first antenna 1001 into a low-frequency signal and a high-frequency signal. The control unit 1003 is electrically connected to the first duplexer 1002 and is used for judging the signal strength of the low frequency signal and the high frequency signal separated by the first duplexer 1002 . The first c...

Abstract

The invention relates to an antenna device. The antenna device comprises a first antenna, a first duplexer, a control unit, a first matching adjustment unit and a first coupling adjustment unit, wherein the first antenna is used for receiving and sending signals, the first duplexer is electrically connected with the first antenna and is used for separating the signals received by the first antennainto the low frequency signals and the high frequency signals, the control unit is used for determining intensity of the signals received by the first antenna, the first coupling adjustment unit is controlled by the control unit according to the signal intensity of the low frequency signals after separation by the first duplexer for adjusting a resonance frequency point of the first antenna so asto expand the low frequency bandwidth of the first antenna and change the low frequency operation frequency band, and the first matching adjustment unit is controlled by the control unit according tothe signal intensity of the high frequency signals after separation by the first duplexer for adjusting the resonance frequency point of the first antenna so as to expand the high frequency bandwidthand change the high frequency operation frequency band and further expand the low frequency bandwidth of the first antenna and change the low frequency operation frequency band.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an antenna device and a mobile terminal thereof. Background technique [0002] With the development of 4G communication, the frequency range of radio frequency coverage of personal terminal products is getting wider and wider, which makes the bandwidth of terminal antennas expand from 824-960MHZ and 1710-2170MHZ to 698-960MHZ and 1710-2690MHZ. However, terminal products are required to be smaller and thinner, resulting in limited bandwidth and coverage of terminal products, and poor sending and receiving signals of terminal products. The bandwidth range is getting wider and wider but is limited by the size and mechanism of the antenna, which brings great challenges to the antenna design. Contents of the invention [0003] In view of this, it is necessary to provide an antenna device to solve the problem of limited bandwidth, and it is also necessary to provide a...
