Antenna switching system and wireless communication device using the antenna switching system

A wireless communication device comprising:

• an antenna switching system, the antenna switching system comprising:
• a first antenna;
• a second antenna;
• a first sensing configured to detect a distance between an object and the first antenna;
• a second sensing unit configured to detect a distance between the object and the second antenna;
• a controlling unit electronically connected to the first sensing unit and the second sensing unit;
• and
• a switching unit electronically connected to the controlling unit, the first antenna, and the second antenna;
• wherein the controlling unit is configured to determine a holding mode of the wireless communication device based on detections of the first sensing unit and the second sensing unit and activate and deactivate the first antenna and the second antenna via the switching unit according to the holding mode of the wireless communication device;
• and
• wherein the first sensing unit senses that the distance between the object and the first antenna is in a predetermined range, and the second sensing unit senses that the distance between the object and the second antenna is in the predetermined range, the controlling unit determines that the wireless communication device is at a third holding mode and switches the switching unit to a mode that both the first antenna and the second antenna are selected.

A wireless communication device comprising:

• a base board;
• a first metal member, the first metal member positioned at a first side of the base board;
• a second metal member, the second metal member positioned at a second side of the base board opposite to the first metal member;
• and
• an antenna switching system, the antenna switching system comprising:
• a first antenna;
• a second antenna;
• a first sensing configured to detect a distance between an object and the first antenna;
• a second sensing unit configured to detect a distance between the object and the second antenna;
• a controlling unit electronically connected to the first sensing unit and the second sensing unit;
• and
• a switching unit electronically connected to the controlling unit, the first antenna, and the second antenna;
• wherein the controlling unit is configured to determine a holding mode of the wireless communication device based on detections of the first sensing unit and the second sensing unit and activate and deactivate the first antenna and the second antenna via the switching unit according to the holding mode of the wireless communication device.
