Antenna structure and wireless communication device using same

A wireless communication device comprising:

• an antenna structure comprising:
• a feed portion, the feed portion configured to feed current to the antenna structure;
• a first ground portion, the first ground portion spaced apart from the feed portion and configured to ground the antenna structure;
• a first radiating portion, the first radiating portion electrically connected to the feed portion;
• a second radiating portion, the second radiating portion spaced apart from the first radiating portion and electrically connected to the first ground portion;
• and
• a third radiating portion, the third radiating portion spaced apart from the second radiating portion and electrically connected to the feed portion and the first radiating portion;
• wherein the first radiating portion comprises a first radiating section, a second radiating section, a third radiating section, and a fourth radiating section, the first radiating section is positioned at a plane perpendicular to a plane on which the feed portion is positioned, the first radiating section is electrically connected to one end of the feed portion;
• wherein the second radiating section is coplanar with the first radiating section, the second radiating section is perpendicularly connected to one end of the first radiating section away from the feed portion and extends along a direction away from the second radiating portion;
• wherein one end of the third radiating section is electrically connected to one end of the second radiating section away from the first radiating section;
• wherein the fourth radiating section is positioned at a plane perpendicular to a plane on which the second radiating section is positioned, the fourth radiating section is electrically connected to one end of the third radiating section away from the second radiating section.
