Abstract
A multi-band antenna includes a ground, an asymmetric T-shaped radiation element, an inverted L-shaped conduction element, and a parasitic element. The asymmetric T-shaped radiation element has a first radiation part, a second radiation part, and a first conduction part. The length of the second radiation part is shorter than that of the first radiation part. The inverted L-shaped conduction element has a second conduction part and a third conduction part. The second conduction part is connected to the first conduction part, and arranged between the second radiation part and the ground. The parasitic element has a fourth conduction part and a third radiation part. The fourth conduction part is connected approximately perpendicular to the ground. The third radiation part is arranged between the first radiation part and the ground.
