Abstract
A micro antenna driving apparatus is installed in a housing of the mobile phone so as to extend or retract the antenna, and comprises a driving motor, and a decelerator. The driving motor includes a motor body provided with a magnet, and a shaft inserted in the motor body and surrounded by a coil. The decelerator is coupled to the motor body so as to be installed at one end of the shaft, and has an output shaft fixed in the housing. The antenna is installed in the housing such that it comes into contact with the motor body. Thereby, the antenna can be extended or retracted according to rotation of the driving motor while coming into direct contact with the motor body of the driving roller without requiring a separate driving roller, resulting in a reduction in an installation space of the antenna driving apparatus.
