Patent ID: 8593368

Claim:
A multi-band antenna, comprising: an antenna substrate; an antenna ground, located on the antenna substrate, having a signal ground terminal and at least one bend; an antenna unit, located on the antenna substrate, being adjacent to the antenna ground, and providing a first and second operating bands, wherein the antenna unit comprises: a coupling conductor; a feeding conductor, located between the antenna ground and the coupling conductor, extending along the coupling conductor, and having a signal feeding terminal corresponding to the signal ground terminal, wherein there is a first distance between the feeding conductor and the coupling conductor; a radiating conductor, one end thereof being electrically coupled to the coupling conductor, and the other end thereof facing to the antenna ground, wherein there is a second distance between the radiating conductor and the antenna ground; and a shorting conductor, two ends thereof being respectively electrically coupled to the coupling conductor and the antenna ground; and a first matching conductor, one end thereof being electrically coupled to the antenna ground, and the length thereof being about a quarter of the wavelength corresponding to a frequency of the first operating band, wherein there is a first angle between the first matching conductor and the antenna ground.
