Electronic device, mobile terminal and antenna assembly

A mobile terminal, comprising:

• a case comprising a middle frame and a back case, wherein the middle frame and the back case cooperatively define an accommodating groove;
• a movable support integrated with a first antenna, the movable support being slidably connected with the case, and capable of moving out of or retracting into the accommodating groove;
• and
• a first circuit board installed on the middle frame and electrically connected with the first antenna to provide driving signals to the first antenna;
• wherein the case defines a latch slot;
• the movable support comprises a support body and a lock component slidably connected to the support body, the first antenna is installed on the support body;
• the lock component is capable of moving partially into the latch slot to lock the movable support and moving out of the latch slot to release the movable support.

An antenna assembly with a functional device, comprising:

• a movable support adapted to be slidably connected to a case of an electronic device;
• a first antenna installed on the movable support;
• and
• a functional device installed on the movable support, wherein the functional device comprises at least one of:
• a camera, a flash, a structured light sensor, a proximity sensor, a light sensor or a phone receiver;
• wherein the antenna assembly further comprises an antenna switch connected to the movable support or the case;
• different match circuits with different parameters each connected between the antenna switch and the first antenna;
• wherein the antenna switch is configured to select one of the match circuit for correcting frequency offset of the first antenna due to movement of the movable support.
