Abstract
A multi-band antenna includes an antenna substrate, an antenna ground, an antenna unit, and a matching conductor. The antenna ground has a signal ground terminal and at least one bend. The antenna unit is adjacent to the antenna ground. The matching conductor is electrically coupled to the antenna ground, and an angle exists between the matching conductor and the antenna ground. A length of the first matching conductor is about a quarter of the wavelength corresponding to a frequency of the first operating band. The antenna unit includes a coupling conductor, a feeding conductor, a radiating conductor, and a shorting conductor. The feeding conductor has a signal feeding terminal One end of the radiating conductor is facing to the antenna ground, and a distance exists between the feeding conductor the antenna ground. Two ends of the shorting conductor are respectively electrically coupled to the antenna ground and the coupling conductor.
