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...
