Patent ID: 8907860

Claim:
A stand-alone multi-band antenna, comprising: an antenna ground plate; a first radiating unit, being an antenna structure generating a fringing-field, directly connected at least one side of the antenna ground plate and located above the antenna ground plate, used to simultaneously provide a first operating band and a second operating band; a shielding metal wall, connected to a plurality of the adjacent sides of the antenna ground plate, wherein a height of the shielding metal wall is larger than or equal to a height of the first radiating unit, therefore limiting the fringing-field of the first radiating unit within the stand-alone multi-band antenna, wherein the shielding metal wall is formed by extending from the antenna ground plate; a signal feed-in source, having a signal feed-in point and a ground point, wherein 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; wherein the shielding metal wall is located on neighboring sides of the antenna ground plate neighbored to at least one side of the first radiating unit.
