Antenna structure and wireless communication device using same

A wireless communication device, comprising:

• an antenna structure, the antenna structure comprising:
• a metallic member, the metallic member comprising a front frame, a backboard, and a side frame, the side frame being positioned between the front frame and the backboard;
• a first feed portion;
• a first matching circuit comprising an extractor;
• and
• a second matching circuit comprising a third inductor and a third capacitor;
• wherein the side frame defines a slot;
• wherein the front frame defines a first gap and a second gap, the first gap and the second gap are between two opposite ends of the slot, the first gap and the second gap communicate with the slot and extend across the front frame;
• and
• wherein a portion of the front frame between the first gap and the second gap forms a first radiating section, one end of the first feed portion electrically connects to the first radiating section, the other end of the first feed portion connects to a first feed source and a second feed source through the extractor;
• an end of the first radiating section adjacent to the second gap connects to a ground through the third inductor and the third capacitor.
