摘要
PURPOSE: A small antenna apparatus and a control method thereof are provided to use space efficiently, by connecting an electric circuit to a feeding line and both ends of an antenna. CONSTITUTION: A first electric circuit (120) is connected between both ends of an antenna pattern and a system ground respectively. A second electric circuit (130) is connected between both ends of the antenna pattern and a system ground respectively. A third electric circuit (140) is located between the antenna pattern and a feeding line. The first, the second and the third electric circuit extends electrical wavelength of the antenna pattern. The first, the second and the third electric circuit improves input impedance matching.
