PURPOSE: A built-in antenna for a headset is provided to improve sound quality of an audio signal by excluding external influence like hand effect or head effect. CONSTITUTION: A substrate(100) is arranged inside a headset body. A feeding pattern(102) is formed on a substrate. A rotation unit(104) is rotatably arranged on the substrate. The rotation unit is made of a metal material. The rotation unit is electrically connected to the feeding pattern. A part of the rotation unit is protruded from the housing of the head set. A hanging unit(106) is coupled with an upper side of the rotation unit. A radiator(108) is inserted into the hanging unit. The radiator is comprised of a metal wire or FPCB(Flexible Printed Circuit Board).
