Abstract
Disclosed is a stylus pen combined with an antenna in a touch screen type-wireless terminal. The stylus pen has a built-in antenna and is detachably disposed in the touch screen type-wireless terminal, and the built-in antenna makes electrical connection with an antenna contact portion of an RF board of the terminal when the stylus pen is completely inserted in the terminal, such that the terminal has an improved antenna radiation characteristic and quality when compared with a terminal only having a fixed terminal antenna. The built-in antenna in the stylus pen may be a λ/4 dipole antenna or a λ/4 monopole antenna.
