Patent ID: 7425924

Claim:
An antenna for an electronic device, the antenna comprising: a ground plane; a T-shaped radiator having: a first portion perpendicularly connected to the ground plane; and a second portion further comprising a first arm and a second arm, both perpendicularly connected to the first portion and extending parallel to the ground plane in opposite directions; a first L-shaped radiator having: a shorter portion perpendicularly connected to the ground plane with one end thereof, and a longer portion perpendicularly connected to the other end of the shorter portion of the first L-shaped radiator; a second L-shaped radiator having: a shorter portion perpendicularly connected to the ground plane with one end thereof; and a longer portion perpendicularly connected to the other end of the shorter portion of the second L-shaped radiator; and a feeder cable having: a positive signal wire electrically connected with the first portion of the T-shaped radiator; and a negative signal wire electrically connected with the ground plane; wherein the length of the first arm is different from that of the second arm, the longer portion of the first L-shaped radiator and the second arm of the T-shaped radiator extend in the same direction and the longer portion of the first L-shaped radiator is spaced apart from the first arm of the T-shaped radiator, and the longer portion of the second L-shaped radiator and the first arm of the T-shaped radiator extend in the same direction and the longer portion of the second L-shaped radiator is spaced apart from the second arm of the T-shaped radiator.
