Abstract
A stand-alone multi-band antenna includes an antenna ground plate, a shielding metal wall, a first radiating unit, and a signal feed-in source. The first radiating unit connected to at least one side of the antenna ground plate and located above the antenna ground plate is an antenna structure generating the fringing-field. The first radiating unit provides a first operating band and a second operating band. The shielding metal wall is connected to a plurality of the adjacent sides of the antenna ground plate, and the height thereof is larger than or equal to that of the first radiating unit, therefore limiting the fringing-field of the first radiating unit within the stand-alone multi-band antenna. The signal feed-in source has a signal feed-in point and a ground point. The signal feed-in point is electrically connected to the first radiating unit, and the ground point is electrically connected to the shielding metal wall.
