Abstract
An antenna structure for operating multi-band system is disclosed. The antenna structure at least comprises a first radiation metal wire and a second radiation metal wire. These radiation metal wires send signal through the same feed point and provide a ground surface. The radiation metal wires are embedded into the circuit board having a hole. The design avoids the complexity of the antenna structure, reduces cost, and improves production capabilities. The length of the first radiation metal wire is bigger than the second radiation metal wire for using in a low frequency operating band and the second radiation metal wire is used in a high frequency operating band. These radiation metal wires can be fixed into the hole of the circuit board. The entwining of the radiation metal wires can bend according to a space provided by a case. Therefore, the antenna structure can be protected by the case without damages from outside forces.
