Abstract
An antenna structure includes a first frequency band antenna and a second frequency band antenna. The first frequency band antenna is operated at a first frequency band. The second frequency band antenna is operated at a second frequency band, and includes a feeding portion, a balun and at least one antenna unit. The balun is connected to the feeding portion. The at least one antenna unit is connected to the balun. The first frequency band is different from the second frequency band.
