ANTENNA STRUCTURE AND WIRELESS COMMUNICATION DEVICE USING SAME
First Claim
1. An antenna structure comprising:
- a metal housing, the metal housing comprising a front frame, a backboard, and a side frame, the side frame being positioned between the front frame and the backboard, the backboard being grounded;
wherein the side frame defines a slot and the front frame defines a gap, the gap communicates with the slot and extends across the front frame;
the metal housing is divided into at least a long portion and a short portion by the slot and the gap; and
a first feed portion, one end of the first feed portion electrically connected to the long portion for feeding current to the long portion and another end of the first feed portion electrically connected to the backboard;
a first ground portion, one end of the first ground portion electrically connected to the long portion for grounding the long portion and another end of the first ground portion electrically connected to the backboard;
a second ground portion, one end of the second ground portion electrically connected to the long portion for grounding the long portion and another end of the second ground portion electrically connected to the backboard; and
a radiator;
wherein the radiator is positioned in the metal housing, electrically connected to the backboard, and is spaced apart from the short portion.

Abstract
An antenna structure includes a metal housing, a first feed portion, a first ground portion, a second ground portion, and a radiator. The metal housing includes a front frame, a backboard, and a side frame. The side frame defines a slot and the front frame defines a gap. The metal housing is divided into at least a long portion and a short portion by the slot and the gap. One end of the first feed portion is electrically connected to the long portion for feeding current to the long portion and another end of the first feed portion is electrically connected to the backboard. The first and second ground portions are both electrically connected to the long portion for grounding the long portion. The radiator is positioned in the metal housing, electrically connected to the backboard, and is spaced apart from the short portion.
