An antenna includes a substrate, a radiation portion, and a signal feed-in portion. The radiation portion includes a first radiation unit and a second radiation unit. The first radiation unit and the second radiation unit are disposed on the same surface of the substrate. The signal feed-in portion is disposed on the first radiation unit. The second radiation unit and the first radiation unit have the same shape and are symmetrical in position, and the second radiation unit is connected to the first radiation unit, such that the first radiation unit and the second radiation unit form a closed loop. Thus, the impedance is improved and a wider bandwidth is achieved.
