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, the front frame defines a first gap and a second gap, the first gap and the second gap both communicate with the slot and extend across the front frame;
the metal housing is divided into at least a first radiating portion and a second radiating portion by the slot, the first gap, and the second gap;
a feed portion, one end of the feed portion electrically connected to the first radiating portion for feeding current to the first radiating portion and another end of the feed portion electrically connected to the backboard; and
a ground portion, one end of the ground portion electrically connected to the first radiating portion for grounding the first radiating portion and another end of the ground portion electrically connected to the backboard;
wherein the second radiating portion comprises a connecting section, a first radiating section, and a second radiating section, the connecting section is perpendicularly connected to the first radiating section, the second radiating section, and the backboard, the first radiating section and the second radiating section are both positioned parallel to the first radiating portion.

Abstract
An antenna structure includes a metal housing, a feed portion, and a ground portion. 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 first gap and a second gap. The metal housing is divided into at least a first radiating portion and a second radiating portion by the slot and the first and second gaps. The feed portion is electrically connected to the first radiating portion. The ground portion is electrically connected to the first radiating portion. The second radiating portion includes a first radiating section, a second radiating section, and a connecting section perpendicularly connected to the first radiating section, the second radiating section, and the backboard. The first radiating section and the second radiating section are both parallel to the first radiating portion.
