An external antenna (100) for a wireless communication device includes a dielectric base (1), a rotatable portion (2) received in the base, a connecting portion (3) connected with the rotatable portion and an antenna element (4) connected with the connecting portion. The dielectric base defines a bore (10) and a groove (12) therein. The rotatable portion includes an upper portion (21) and a block (23) extending from the rotatable portion and slidably engaging in the groove for limiting a rotational movement of the rotatable portion relative to the dielectric base. The connecting portion has an engaging portion (30) connected with the upper portion of the rotatable portion.
