A dual-band dipole antenna is provided with a first conductor arm, a second conductor arm, and a feeding signal line, wherein two conductor arms have different lengths. The feeding signal line has a signal end and a ground end, respectively connected to the feeding points on the two conductor arms. The feeding signal line transmits feeding signals to the two conductor arms through the feeding points, thereby generating two operating modes of the antenna. The desired frequency ratio of a second operating mode and a first operating mode for a dual-band wireless local network is achieved by simply changing the two conductors' relative lengths, so that the frequency ratio of a second operating mode and a first operating mode for the antenna is the same as the desired frequency ratio.
