Antenna structure and electronic device using same

A electronic device, comprising:

• an antenna structure comprising:
• a back board defining a slot;
• a side frame made of metal material and positioned at a periphery of the back board, wherein the side frame defines at least a first gap and a second gap, the slot is defined at an edge of the back board near the side frame and communicates with the first gap and the second gap;
• wherein the first gap and the second gap divide a first radiation portion and a second radiation portion from the side frame;
• a first feed point positioned on the first radiation portion and being electrically connected to a first feed source for feeding current and signal to the first radiation portion;
• a second feed point positioned on the second radiation portion and being electrically connected to a second feed source for feeding current and signal to the second radiation portion;
• and
• a first ground point positioned on the first radiation portion and between the first feed point and the second feed point;
• wherein when the first feed point and the second feed point supplies current, the first radiation portion and the second radiation generate at least one same radiation frequency band, when current is fed from the first feed point, the first radiation portion excites a GPS mode, a WIFI 2.4 GHz Mode, a WIFI 5 GHz mode and a licensed spectrum auxiliary access (LAA) mode, when current is fed from the second feed point, the second radiation portion excites the WIFI 2.4 GHz mode, the WIFI 5 GHz mode and the LAA mode;
• and
• wherein the side frame between the first gap and the second gap forms the first radiation portion, a portion of the side frame which extends from the second gap along a direction away from the first gap and the first radiation portion forms the second radiation portion.
